MODULE 7 EXAM: PORTAGE
BIOCHEMISTRY, 2024/2025 WITH
CORRECT/ACCURATE ANSWERS
Which number on the molecule below indicates the
α and β carbons?
Carbon 2 is the alpha, and Carbon 3 is the beta.
A scientist uses the term flux regarding a
biochemical pathway. What does flux mean?
Flux is the rate of flow through a biochemical pathway.
A particular pathway breaks down proteins into
amino acids. Is this an anabolic or a catabolic
pathway?
Catabolic. This is degradation of a molecule.
What molecule (FADH2, ATP, ADP, or CoA) is shown
below?
, ADP
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
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)
What is the "ETC" and what happens there?
Electron transport chain. NADH is converted into ATP
