What physiological symptoms would you exhibit

1. ATP comes primarily from the breakdown of glucose. If your blood glucose level drops, what physiological symptoms would you exhibit?

2. If cellular respiration were the stock market (you are investing ATP and getting ATP dividends), where would you get the most return on your investment: glycolysis, the Krebs cycle, or the electron transport chain? Explain your choice.

3. Under aerobic conditions, one of the products from glycolysis can be used in the Citric Acid Cycle, but it must first be converted to what before it can be used? In the Citric Acid Cycle (Krebs’ Cycle) what and how many of each energy rich molecules are produced? Where in a eukaryotic cell does the Citric Acid Cycle take place?

4. After the complete oxidation of glucose via glycolysis and the Krebs cycle, most of the energy once stored in a glucose molecule is now stored in molecules of ATP, NADH and FADH2. Remembering that each energy conversion is not 100% efficient, what has happened to the remaining energy

5. In the light-dependent reactions:

A. carbon dioxide is fixed.
B. ATP and NADPH form.
C. CO2 accepts electrons.
D. sugars form.

7. Which of the following describe(s) some aspect of metabolism?

A. synthesis of macromolecules
B. breakdown of macromolecules
C. control of enzyme activity
D. A and B only
E. A, B, and C
