CHEM 210 Module 7 Exam Newest
1. A scientist uses the term flux regarding a biochemical pathway. What does
flux mean?: Flux is the rate of flow through a biochemical pathway.
2. A particular pathway breaks down proteins into amino acids. Is this an
anabolic or a catabolic pathway?: Catabolic. This is degradation of a molecule.
3. The acetyl group is connected to CoA to make Acetyl-CoA. A) What specific
atom of CoA connects to the carbon atom on the acetyl group? B) What
nucleotide base is part of CoA?: A) Sulfur B) Adenine
4. Both carbohydrates and lipids are broken down into Acetyl-CoA for further
processing. What pathway does Acetyl-CoA go to next?: Citric Acid Cycle (CAC)
1/5
, 5. What is the "ETC" and what happens there?: Electron transport chain. NADH
is converted into ATP at the ETC.
6. What is the sign (+ or -) of ”G for the breakdown of ATP to ADP? Why is the
sign important?: (-). A negative means spontaneous, or favorable, and is able to
power other processes.
7. What are the two phases of glycolysis? How many reactions in each?: The
preparatory phase and payoff phase. Five reactions in each.
8. How many ATPs are invested in glycolysis?: 2
9. What is the net number of ATP gained from glycolysis?: 2 (2 invested, 4
gained, for a net of 2)
10. How many reactions of glycolysis have a single arrow "’" in their reaction
equation?: 3
