Photosynthesis and cellular respiration are important biological processes. Photosynthesis involves plants using sunlight, carbon dioxide, and water to produce oxygen and energy in the form of glucose. Cellular respiration is the process by which organisms generate energy by breaking down glucose and oxygen to produce carbon dioxide, water, and energy.
Earth and Life Sciences for Senior High School by Duyanen and Andaya pages 176-179
My fun and colorful grade 11 report on Life Sciences 2nd semester of A.Y. 2016-2017 under Ms. Lagmay
Detailed description of photosynthesis and respiration along with a recap on enzymes (SIMPLIFIED)
For a good insight on bioenergetics visit http://www.sumanasinc.com/webcontent/animations/content/cellularrespiration.html
For this assignment, we were instructed to create a powerpoint presentation of at least 12 slides that adequately covered an academic subject of our choice. All sources for media is cited in the work cited at the end of the presentation.
Touring the Universe (An Introduction to Formation of the Universe)
I hope this lesson can shed light to SHS Grade 11 Science Teachers. My appeal to those who will download this ppt. please email me at marileahmendina08@gmail.com for my own references. I would be glad to hear from you.
Another productive school presentation. Again, it contains mostly icons or pictures since when i do reporting, words come out either directly from my mouth or from the participants. it will be easy if you read super duper much first before you consider this presentation. BTW, i called it, ENERGY UTILIZATION.
Happy days are coming your life!!!

Sunlight and water enter photosystems within the thylakoid to begin the light dependent reactions. The energy from the sun excites electrons in the photosystems, causing the electrons to travel down electron transport chains. As the electrons move down the ETCs they create NADPH, which is a special electron carrier.
Simultaneously, water is split into hydrogen ions, H+, electrons, and O2. The O2 is released as a byproduct. The H+ are used to create a concentration gradient across the thylakoid membranes.
At the end of the ETC there is a membrane protein (also an enzyme) called ATP synthase-the H+ flow from high to low through the protein, creating ATP for the cell (called chemiosmosis). The ATP and NADPH made during the LDRs and CO2 from the atmosphere activate the second step called the Calvin Cycle, which happens in the stroma (fluid) of chloroplasts.
The Calvin Cycle is a series of chemical reactions that rearranges the carbon from CO2 into glucose, C6H12O6 using the energy from ATP and NADPH.
In the cytoplasm, the process of glycolysis splits glucose into 2 molecules of pyruvate. Glycolysis also releases 2 molecules of ATP.
Pyruvate enters the mitochondria, where it starts the Krebs cycle.The Krebs cycle releases 2 molecules of ATP and CO2 as a waste product. The main products of the Krebs cycle are special energy carriers-NADH and FADH2.
The NADH and FADH2 enter the electron transport chain. Oxygen is also needed to activate the electron transport chain. As the electrons from NADH and FADH2 move down the electron transport chain, 32 molecules of ATP are released.Water is released as a by-product of the electron transport chain.
