How much ATP is produced per NADH molecule after oxidative phosphorylation?
Per FADH2? - ANSWER-NADH- 2.5 per molecule. FADH2 - 1.5 per molecule
How many CO2 are lost per each turn of the CAC? - ANSWER-2 molecules of
CO2 are lost.
How many of the steps in the CAC are equilibrium reactions? - ANSWER-5
What reaction is catalyzed by the PDH? - ANSWER-pyruvate to acetyl-CoA
Given the diagram of the citric acid cycle, answer the following questions.
, A. (1 pt) What compound is the five-carbon molecule? (contains 5 carbons)
B. (2pt) Identify the four-carbon compounds.
C. (1 pt) How many GTP molecules are produced per turn of this cycle?
D. (1 pt) What is one reaction that is an equilibrium reaction? (give reaction
number) - ANSWER-A. a-ketoglutarate
B. Succinate, fumarate, malate, and oxaloacetate
C. 1 GTP
D. Any one of 2, 5, 6, 7, and 8
The B-oxidation pathway is the degradation pathway for fatty acids.
A. Where, in the cell, does the B-oxidation pathway occur?
B. How many steps are in the B-oxidation pathway? - ANSWER-A. In the
mitochondria.
B. Four reaction steps.
How many FADH2 and NADH molecules are produced per round of B-oxidation?
- ANSWER-One of each FADH2 and NADH.
Which number on the molecule below indicates the A and B carbons? - ANSWER-
Carbon 2 is the alpha, and Carbon 3 is the beta.
Can B-oxidation occur with odd-numbered fatty acids? Can B-oxidation occur
with fatty chains containing double bonds? Explain your answer in at least three
complete sentences. - ANSWER-Yes to both types of chains. The B-oxidation
process occurs with both unsaturated fatty acids (those with double bonds) and
fatty acids that have an odd number of carbons. Double bonds and odd-numbered
chains each present a structural problem for the standard enzymes of the pathway.
