An incredibly sarcastic science powerpoint that focuses on Cellular Respiration and Photosynthesis. Krebs Cycle anyone?

1. Energy PowerPoint 4
studying
Rose Shaw

2. ok
• So at the end of this powerpoint there are 3 slides with a bunch of
random humorous stuff on them and I hope that every time you
don’t understand something, you go to the end of the PowerPoint,
read a bunch of jokes, and relax and come back ready to learn
• They’re even funnier at 1 in the morning after a frantic study session
• And I kept it school appropriate!!!!!

3. Energy
• The ability to do work

4. Thermodynamics
• The study of the flow and transformation of the universe
• First Law: Law of Conservation of Energy – energy cannot be created or
destroyed, can change forms
• Second Law: Law of Entropy – energy cannot be converted into other forms
without some loss
• Entropy – chaos or unusable energy

5. The Trophs
• Autotrophs
• Organism capable of making its own food – they automatically do it, auto-
means self (its freaking Greek) they can
• Photoautotroph
• Using sun energy to make energy – hello this is photosynthesis thank you very
much
• Chemoautotroph
• Using chemical energy from inorganic substances – this is like those weirdos on
TV that are addicted to eating mattresses – only they eat things like methane
gas
• Heterotroph
• Cannot make their own food – CANNIBALISM - humans

6. mETAbolism
• Metabolism
• How cannibals (heterotrophs) obtain food – all chemical reactions within a
cell
• Catabolic – catastrophic - Pathways boom boom fall to pieces
• Larger Molecules break down
• Anabolic pathways
• Cell energy used to build large molecules THIS IS PHOTOSYNTHESIS PLEASE
KNOW THIS

7. Atp
• Formed by light and water! This is why plants need it those things!
• Adeninoniedfwsds tri-something or another (atp)
• Adenine Triphosphate
• Organic (does it matter that its organic?) molecule with high-energy (Fancy)
phosphate bonds
• This organism gets energy from breaking those fancy high-energy phosphate
bond with CARBON DIOXIDE….
• After the bond is broken, ADP is made
• ATPase – it’s a race to the finish with this speedy lil’ enzyme – used to break
apart ATP
• ATP synthase – technical opposite of ATPase – this speeds up the rebuilding of
ATP – OPPOSITE
• Used by EVERYTHING

8. Have some rather important vocab!!
• Photosynthesis
• The process of converting light into chemical energy
• Strona
• Has enzymes, is like a pus ball outside of the grama
• Grama
• Sacs of thylakoid
• Photon
• A packet of solar energy (it’s like a photo of light!!)
• Chloroplasts
• Organelles that capture light
• ****** FORMULA FOR PHOTOSYNTHESIS
• 6CO2 + 6H20 -----> C6H1206 + 6O2
• Carbon + water + light --- Glucose + Oxygen (fact, cellular
respiration is THE EXACT OPPOSITE OF THIS)

9. pHotosynthesis
• Pigments are colors pigment are colors pigments are colors
chlorophyll is green luscious lovely
• Hello. Yes there are two stages of this:
• First up Is light-dependent reactions aka the electron transport
• LIGHT MUST BE GATHERED LIKE THE BERRY IT IS it combines with water to
make ATP, NADAH, and oxygen, but only the first two are important. Oxygen
is useless.

10. What do you mean
that’s not a pigment

11. Photosystems (2 right now, promise 1 is
coming)
• (photosystems) These hold colors (the pig-men) are also proteins
complexes!
• First up, strangely enough is photosystem 2 which is nonsensical
but easy to remember.
• The light energy excites the electrons (gutter-mind here) and causes a
water molecule to split. Remember when light and water combined to get
ATP and NADAH? Yeah. That water molecule.
• That water molecule splitting causes: A wild electron charging towards the
electron transport line, a hydrogen ion going to the thylakoid (it sounds
water going to them thighs? Idk) and oxygen. But we don’t care about
oxygen. Oxygen is trash. Repeat after me.

12. Photosystem 1 as promised!!
• After the water molecule splits and releases a wild electron, my notes say and I quote: “to
an acceptor molecule in the thylakoid membrane - transfers the electron along a series of
electron carriers to photosystem 1” but idk about that first part so essentially
• The electron goes through a moving sidewalk and ends up in photosystem 1
• He downgrades from 2 to 1
• ******ALSO THIS IS IMPORTANT PAY ATTENTION – OKAY SO WHEN WATER BREAKS DOWN (…splits) IT
PROVIDES SOME PRETTY IMPORTANT PROTONS FOR THE FORMATION OF ATP synthesis. REMEMBER THAT?
Its ok I don’t either, but it’s the enzyme that sped up the rebuilding of ATP
• WHAT IS FERREDOXIN?
• I like that word ‘ferredoxin ferredoxin ferredoxin’
• Its this cool lil protein that takes the wild electron down the moving sidewalk aka electron transport
and puts it in a carrier molecule to be safe for its journey down the moving sidewalk. This is caused by
the light. Solar.
• Also forms NADP+ which helps form NADAH but how

13. chemiosmosis
• More like chemiosNOsis.
• How ATP is produced using electrons! Involves a concentration
gradient! And electron transport system! And electrons going to
down the Concentration gradient!
• Water and light and carbon dioxide are the reactants in
photosynthesis

14. PHOTOSYNTHESIS P2
• THE CALVIN AND HOBBES CYCLE
• Aka light independent cycle
• Where is the energy?
• In glucose really
• THIS DOES NOT NEED THE SUN ITS TOO GOOD FOR THAT CRAP

15. Carbon obsession
• Step one of the Calvin Cycle
• Carbon fixation
• Carbon dioxide bonds with 5-carbon molecules and then give birth to a 3-
phosphoglycerate (3-PGA) (yes that was a copy/paste)
• Step two of the Calvin Cycle
• Energy, the poor unwanted child, is thrown from ATP and NADAH to 3-PGA
and along the way makes More Complicated Things and the end result is
glyceraldehyde 3-phosphate (G3P) (another copy/paste)

16. calvin
• Step three of the Calvin Cycle
• Some G3P (the result of energy being tossed around) leave the cycle to
forge their own way in the world – haha just kidding their fate is set in
stone they will be used for the production of glucose
• Snazzy we have a factory worker
• Step Four of the Calvin Cycle
• The G3P that remained within the life given to them are converted into 5-
carbon molecules which has a long and Complicated name that is ribulose
1.5-bisphosphate. But we call him rubber puppy (RuBP)
• This conversion uses the enzyme RUBISCO™
• The rubber puppy continues the cycle by combining with carbon dioxide

17. facts
• Carbon Dioxide is used to make glucose
• Water and light make oxygen
• The light-dependent reaction is divided into the two photosystems
• Calvin Cycle has four distinct steps
• Cycle – it never ends
• Ugh I don’t care how plants are made as long as they keep doing
this
• This is an Anabolic pathway

18. HI
• Take a break from studying now!! Check back in in about give or
take thirty minutes and use some sort of quizlet to check your
knowledge! Learning isn’t memorizing – its knowing. The best way
to know is to actively forget.
• Read a book. Do other homework. Sit and listen to music. Take a
shower. Idk man your past self is smart maybe

19. Part. Two. y’all
Cellular respiration!!! I want fruits basket man… after you pass the
test rose you dumb child

20. What is cellular respiration?? - a simple
summary
• It is a catabolic process. (check out slide 5)
• Photosynthesis is anabolic
• Steals electrons from other molecules, murders them, and uses
the bodies for energy
• Yeah suck it briarcrest murder will be mentioned here
• Its formula is the reverse of photosynthesis, so once you know one
you know the other

21. OKAY the processes
• Anaerobic process – DOES NOT TECHNICALLY NEED OXYGEN –
Anaerobic/Anti(oxygen)aerobic
• Glycolysis (however glycolysis can use oxygen,
• Aerobic respiration – MOST DEFINITELY NEEDS OXYGEN – idk the
first syllable is pronounced ‘air’ and oxygen is in the air so
• Krebs cycle
• Electron transport
• Cellular Respiration is split into Glycolysis and Aerobic/Anaerobic
Respiration
• If Glycolysis goes into Aerobic respiration, it needs oxygen
• If Glycolysis goes into Anaerobic process, it DOES NOT need oxygen (this is
fermentation)

22. Glycolysis – why is this word so annoying to
look at
• Here, glucose is subtly stashed away within cytoplasm and broken
down
• Hidden deep within the glucose lies these hidden treasures
• 2 molecules of ATP – energy for one’s health bar
• 2 molecules of NADAH – EXTRA energy for the health bar
• 2 molecules of pyruvate – This is like a horse, because then this lil item
travels around non-stop jk EXTRA EXTRA ENERGY THIS IS WHAT YOU NEEDED.
TO DEFEAT THE BOSSMAN
• PYRUVATE KEEPS SHOWING UP MAKE IT STOP GOD

23. pRYUVATE (and the Krebbs cycle
• Where the real energy is hidden within the glucose
• OKAY OKAY OKAY******
• So, now the Krebs (its like Mr. Krabs!!) cycle is happening.
• Remember how I said the Krebs cycle NEEDED oxygen (because it’s a aerobic
process). Yeah. Well you need oxygen to convert pyruvate into carbon
dioxide!!
• How does one convert pyruvate into carbon dioxide? I’m glad you asked!!!
• The prequel – pyruvate does the frick-frack with coenzyme A (CoA) in order to
give birth to acetyl CoA
• Acetyl CoA moves into the Mitochondrial Matrix and alongside a 4-carbon
compound - not quite as good as 5-carbon but eh gets the job done - makes
some spicy citric acid (here I am thinking lemons if you know what I mean – yes
hello internet users in 2011)

24. Citric acid KREBS CYCLE CONTINUED
• Our lemony 2011 juice-friend citric acid is now taken apart to reveal:
• 2 carbon dioxide
• 1 ATP
• 3 NADH
• 1 FADH(2)
• The NADH and FADH are electron carriers, which means they are going to carry things through
the electron transport – or something like that
• ELECTRON TRANSPORT
• This is also an aerobic process (respiration)!! Why? BECAUSE IT NEEDS OXYGEN
• Takes up residence within the Mitochondrial Membrane (which is essentially just the
Mitochondria) – NOT TO BE CONFUSED WITH THE MITOCHONDRIAL MATRIX WHICH while
they sound the same ARE NOT
• Heh the matrix im great this has never been done before
• OKAY BACK TO SCIENCE NADH and FADH are both used to change ADP into more ATP. Why? I’m
almost certain its for more energy! When in doubt talk about energy!!
• Oh yeah and there’s water here as well
• It’s a effect poor bby water just wants to be loved
• Photosynthesis is like electron transport and chemiosmosis in aerobic respiration

25. *takes a deep breath*
• A single glucose molecule can make up to thirty-six ATPs dang man
that’s a lot
• WHAT MAKES ATP INDSIDE THE GLUCOSE MOLECULE??!?!?!?
• The cycle of glycolysis makes TWO atp molecules
• The Krebs Cycle makes uno (1)
• The electron transport makes a whopping 32-33
• The 36 ATPs make up only 36% of the energy from glucose – the rest of the
energy is lost to chaos (entropy) as heat

26. prokaryotes
• Prokaryotes have the special ability to preform aerobic respiration
(yes they still need oxygen)
• Since they do not have mitochondria (remember these are the
dumb cells), the electron transport takes place in the cell
membrane, which is really the only thing prokaryote cells have

27. Ah look the anaerobic respiration
• Here’s your friendly neighborhood reminder – THIS. PROCESS
DOES. NOT. NEED. OXYGEN.
• Since no oxygen is available for the aerobic process, which is the
Krebs Cycle and electron Transport, fermentation happens

28. Fermentation
• Fermentation occurs within the cytoplasm of the cell
• Produces:
• NADH+
• Guess what else
• Is it ATP Rose?????
• Yes! It is!
• Can we read Fruits Basket now?
• no.

29. Lactic acid fermentation or something I guess
• GUESS WHAT CAUSES CRAMPS
• THESE BAD BOYS NO WHY MUST THEY EXSIST
• Shove off periods suck
• Enzymes convert pyruvate made through glycolysis (wow that was what
like slide 21) into lactic acid
• Uhm doesn’t glycolysis sometimes need oxygen? How does this work if
Fermentation doesn’t need oxygen?
• Okay. Re-explanation: So, glycolysis may or may not need oxygen – (variable be
like) – it depends on if it goes into respiration (needs oxygen - aerobic) or into
fermentation (does not need oxygen – anaerobic)

30. ALCOHOL
• Alcohol Fermentation
• Hello yeast and alcohol what a great day
• This occurs in yeast and various bacterias
• This converts pyruvates into ethyl alcohol and carbon dioxide
• This fermentation should be yeast of your troubles for the test
• Hahahah yes I’m hilarious shut up
• Wasn’t there a manga that adequately described this?

31. yes

32. hello
I really like this picture look
at that Ombre hnnnnnnn

33. Similar but yet different
• Aerobic VS Anaerobic – first one needs oxygen, second
does not – picture is a good example
• Autotroph VS Phototroph VS Chemotroph VS
Heterotroph
• First one does its own thing to make food, second is
photosynthesis, third uses crazy stuff like methane gas (here’s an
example! Theses are pretty unconventional creatures, did a report
for EC on these lil guys) to live and the last is essentially humans –
consumers, we eat everything that doesn’t kill us
• Catabolic VS Anabolic – Catabolic -> catastrophe
(breaking things down; Cellular Respiration), while
Anabolic -> assuages (builds things back up again;
Photosynthesis)

34. Similar yet different p2
• ATPase VS ATP synthase – Used to break DOWN ATP, like one might
break a vase (ATPase? Anyone?) – Used to BUILD ATP, uh, just remember
this I’m not awake enough to think of something
• Stroma VS Grama – not too alike but eh – Grama are these sacs of
thylakoid, Stroma is outside of it, and it contains these cool lil enzymes
meant for photosynthesis
• 3-phosphoglycerate (3-PGA) VS glyceraldehyde 3-phosphate (G3P)
• Uh they’re both in the same cycle and have long and complicated names that
involve ‘3’ and ‘p’
• Ok, so 3-PGA comes first in the Calvin cycle, and basically is like the parent of
G3P. G3P is used for producing glucose and being converted into RuBP (Rubber
puppy!!!)
• But Rose! How do we remember the difference between them?
• IDK figure it out yourself you freeloaders 3-PGA came first and has longer initials than G3P
so G3P is like a watered-down version I guess

35. Similar yet different p3
• Mitochondrial Matrix VS Mitochondrial Membrane – the first
one is simply where things are converted, second one is the actual
molecule Mitochondria
• Lactic Acid VS Alcohol Fermentation – while both use pyruvates,
they convert said thing into different things
• Lactic Acid turns pyruvate into… lactic acid oh my gosh
• The alcohol way turns it into ethyl alcohol and carbon dioxide

36. KNOW THIS BACKWARDS AND FORWARDS -
LITERALLY
•6CO2 + 6H20 -----> C6H1206 + 6O2
•Carbon + water + light ---
Glucose + Oxygen

37. Remember to study!
• Write things down! Use quizlet! Do not just use this powerpoint!
Drive the notes home!
• This was just a conventional way to figure it all out
• I hoped this helped
