1. Cell Respiration
Bio Analyze photosynthesis and cellular respiration in terms of how energy is stored, released, and transferred within and between these systems.

2. Cell Respiration
Cell Respiration = the process of breaking down organic compounds such as glucose to produce ATP.
Both plants and animals use cell respiration
Break down organic molecules to make CO2 and H2O
Cell Respiration mirrors photosynthesis
Photosynthesis: light + 6H2O + 6CO2  C6H12O6 + 6O2
Cell Respiration: C6H12O6 + 6O2  6H2O + 6CO2 + ATP

3. Cell Respiration 2 parts of cell respiration:
Glycolysis – break down of sugar
Aerobic respiration – Utilizing oxygen to make ATP through 2 processes
Krebs Cycle
Electron Transport Chain

4. Glycolysis Occurs in the cytoplasm Breaks down glucose
Makes net 2 ATP and pyruvic acid

5. Aerobic Respiration
Aerobic respiration occurs when oxygen is available
Takes place in the mitochondria
2 Steps:
Krebs Cycle – takes place in mitochondrial matrix and produces CO2 and net 2 ATP
Electron Transport Chain – takes place on inner membrane and produces H2O and net 34 ATP

6. How does cell respiration and photosynthesis work together?

7. Fermentation
Fermentation = additional biochemical pathway if oxygen is not present which is known as Anaerobic Respiration
Occurs in the cytoplasm
2 steps of Fermentation
Glycolysis – break down sugar
Fermentation – no oxygen present

8. Fermentation Two Types of Fermentation: Lactic Acid Fermentation
Alcoholic Fermentation

9. Lactic Acid Fermentation
Converts pyruvic acid into lactic acid
Produces 0 ATP
Lactic acid fermentation occurs with muscle fatigue
Can be used to make dairy products

10. Alcoholic Fermentation
Converts pyruvic acid into ethyl alcohol and CO2
Produces 0 ATP
Can be used to make alcohol such as beer, wine, and bread
