Write out the cell respiration equations below: How does this compare to the photosynthesis equation? of electrons. 4. Oxidation is a of electrons, while reduction is a 5. How efficient is the conversion from glucose to ATP? 6. How many ATP molecules are made from one molecule of glucose? 7. In general, what are NAP+ and FAD? 8. Define anaerobic: Aerobic 9. Summarize the 4 phases (used to be considered 3) of Cellular Respiration: a) Glycolysis- b) Prep reaction - c) Citric Acid Cycle - d) ETC Fill in the following chart with the information from your reading: ATP made? What comes out: What goes in: Phases: Where it takes place:

Answer 1

1. Components of an ATP molecule
i. Adenine base
ii. Ribose sugar
iii. Three phosphate groups

2. ATP is the universal cellular energy currency
i.e. All living organisms both prokaryotes and eukaryotes utilize ATP as the energy source.

3. Aerobic respiration:
Glucose + 6O2 --------> 6CO2 + 6H2O + Energy

Photosynthesis:
6CO2 + 12H2O -------> Glucose + 6O2 + 6H2O

In respiration, glucose is oxidized to produce CO2.
In photosynthesis, CO2 is reduced to produce glucose.

4. Oxidation:
i. Loss of electrons
ii. Increase in oxidation number
Reduction:
i. Gain of electrons
ii. Decrease in oxidation number
