The document discusses photosynthesis and cellular respiration. It explains that: 1) Photosynthesis uses light energy, carbon dioxide, and water to produce glucose and oxygen. The products of photosynthesis are then used as reactants in cellular respiration. 2) Photosynthesis stores energy in chemical bonds, while cellular respiration releases energy by breaking those bonds. 3) There are two types of cellular respiration - aerobic respiration, which requires oxygen and produces much more ATP, and anaerobic respiration which occurs without oxygen and produces less ATP.

1. L.18.9 – Photosynthesis and Cellular Respiration
Explain the interrelated nature of photosynthesis and cellular respiration.
1. Explain how reactants and products of photosynthesis are used as reactants for
cellular respiration and vice versa.
2. Explain how photosynthesis stores energy and cellular respiration releases energy.
3. Identify the reactants, products and/or the basic function of photosynthesis.
4. Identify the reactants, products, and/or the basic functions of aerobic and anaerobic
cellular respiration.
5. Connect the role of ATP to energy transfers within the cell.
6. Discuss the role of anaerobic respiration in living things.
Key Vocabulary: ATP, aerobic, anaerobic, cellular respiration, centriole, chloroplasts, photosynthesis,
products, reactants

2. • Photosynthesis is the process by which autotrophic organisms use
light energy to make sugar and oxygen gas from carbon dioxide and
water
Formula for PHOTOSYNTHESIS
Carbon
dioxide
Water Glucose Oxygen
gas
PHOTOSYNTHESIS
6 CO2 + 6 H2O + light energy → C6H12O6 + 6 O2

3. Redox Reactions
Equation for photosynthesis
6 CO2 + 6 H2O + light energy → C6H12O6 + 6 O2

4. Overall purpose:
Photosynthesis - overview
• photosynthesis –
light chemical energy
• complements
respiration
Energy for all life on
earth ultimately comes
from photosynthesis

5. Photosynthesis: An Overview
• The net overall equation for photosynthesis is:
• Photosynthesis occurs in 2 “stages”:
1. The Light Reactions (or Light-Dependent
Reactions)
2. The Calvin Cycle (or Light-Independent
Reactions)
5
6 CO2 + 6 H2O C6H12O6 + 6 O2
light
Is photosynthesis an ENDERGONIC
(ender means in) or EXERGONIC
(exer –means out) reaction?

6. Aerobic Respiration: requires oxygen
• Occurs in the mitochondria of the cell
• Total of 36 ATP molecules produced
• General formula for aerobic respiration:
C6H12O6 + 6O2 6 CO2 + 6H2O + 36 ATP
glucose + oxygen carbon dioxide + water + energy
Human cells contain a
specialized structure – the
mitochondrion – that
generates energy.

7. Summary:
3 steps:
1st glycolysis
2nd Krebs cycle
3rd Electron Transport Chain (ETC)

8. Anaerobic Respiration: occurs when no oxygen is
available to the cell (2 kinds: Alcoholic and Lactic Acid)
• Also called fermentation
• Much less ATP produced than in aerobic respiration

9. •Alcoholic fermentation—occurs in bacteria and
yeast
Process used in the baking industry—yeast
produces CO2 gas during fermentation to make dough
rise and give bread its holes
glucose ethyl alcohol + carbon dioxide + 2 ATP

10. •Lactic acid fermentation—occurs in muscle cells
Lactic acid is produced in the muscles during rapid
exercise when the body cannot supply enough oxygen
to the tissues—causes burning sensation in muscles
glucose lactic acid + carbon dioxide + 2 ATP

11. glycolysis
Anaerobic Respiration
Alcoholic fermentation
Bacteria, Yeast 2 ATP
Lactic acid fermentation
Muscle cells 2 ATP
Aerobic Respiration
36 ATP
ETC
Mitochondria
Krebs

Cytoplasm
•First step in anaerobic respiration is also glycolysis

12. •All energy is stored in the bonds of compounds—
breaking the bond releases the energy
•When the cell has energy available it can store this
energy by adding a phosphate group to ADP, producing
ATP
