Study Guide
11. What is chemiosmosis and how does it work to generate ATP?-The process of
chemiosmosis dries ATP synthesis using the potential energy of a concentration
gradient of hydrogen ions across a membrane.
1. What is a redox reaction?
-A redox reaction is where both oxidation and reduction take place.
2. What is the primary electron carrier in energy metabolism? How does it work? - NAD+
is the primary electron carier used in energy metabolism. It works by acoepting
electrons from other molecules and becoming reduced.
12. What is the highest yield of ATP possible for one molecule of glucose undergoing
aerobic respiration? How do you get that number?
- 38 ATP. 2 NADH produced in glyoolysis (3 ATP each), plus 8 NADH produced in Krebs
cycle (3 ATP each), plus 2 FADH2 (2 ATP each). plus 2 ATP produced in the Krebs
cycle +2 ATP produced in Glycolysis = 6+24+4+2+2=38.
3. What is the function of ATP? What are the two main mechanisms for ATP generation? -
ATP captures chemical energy obtained from the breakdown of food molecules and
releases it to fuel other cellular processes. The two main mechanisms of ATP generation
are substrate-level phosphorylation and axidative phosphorylation through the process
pf chemiosmosis.

4. In glycolysis what are you starting with? What do you end with? - Glycolysis starts with
one molecule of glucose and ends with two pyruvate molecules, four ATP molecules,
and two NADH molecules.
End Products
5. What is your total ATP generation in glycolysis and your net ATP generation?
-Glycolysis produces two pyruvate molecules, a net gain of two ATP molecules, and two
NADH molecules.

6. After glycolysis, what happens to your end prpduct if it is part of a fermentation pathway?
What about if it continues to aerobic respiration? - In the process of fermentation after
glycolysis. The NADH+ H+ will be recycled back to NAD+ so that glyoolysis can
continue. If it continues to aerobic respiration, it will go into three stages: glycolysis, the
Krebs Cycle, and electron transport.
I
7. What do you start with for the Krebs cycle? What do you end up with?
-The Krebs Cycle begins when acetyl-CoA combines with a four-carbon molecule called
OAA. The final product of the Krebs Cycle is oxaloacetic acid.
8. During the one turn of the Krebs cycle, how many NAD+ are reduced? How many FAD+
are reduced? How many ATP are generated by substrate level phosphorylation? -
Three equivalents of reduced NAD+, two hydrogen atoms of FAD+, and one form of
ATP.
9. How many tums of the Krebs cycle per glucose? -Two turns
10. How does the cell harvest the energy from the electrons shuttled in NADH? - It picks up
electrons and becomes reduced when another molecule is oxodized and then transfers
itself to another molecule.
