NP 235 QUIZ 6 FINAL PAPER 2026
COMPLETE Q AND A GRADED A+
⫸ Glycolysis Answer: the breakdown of glucose by enzymes, releasing
energy and pyruvic acid.
⫸ What are the products of glycolysis? Answer: 2 pyruvate, 2 ATP, 2
NADH
⫸ NAD+ Answer: electron carrier involved in glycolysis
⫸ NADH Answer: the reduced form of NAD+; an electron-carrying
molecule that functions in cellular respiration
⫸ FAD Answer:
⫸ FADH2 Answer: A molecule that stores energy for harvest by the
electron transport chain.
⫸ substrate-level phosphorylation Answer: When an enzyme transfers a
phosphate group from a substrate molecule.
⫸ coenzyme A (CoA) Answer: A coenzyme used in various
biochemical reactions as a carrier of acyl groups.
,⫸ Acetyl CoA Answer: Acetyl coenzyme A; the entry compound for
the citric acid cycle in cellular respiration, formed from a fragment of
pyruvate attached to a coenzyme.
⫸ Pyruvate Answer: Organic compound with a backbone of three
carbon atoms. Two molecules form as end products of glycolysis
⫸ carboxylic acids Answer: compounds with carboxyl groups
⫸ citric acid cycle Answer: completes the breakdown of glucose
⫸ GTP Answer: energy source in protein synthesis; guanosine
triphosphate
⫸ Where does glycolysis occur? Answer: cytoplasm
⫸ What cellular respiration processes occur in the mitochondria?
Answer: pyruvate oxidation, citric acid cycle, electron transport chain
and oxidative phosphorylation
⫸ pyruvate dehydrogenase Answer: enzyme complex in the
mitochondrial matrix that catalyzes pyruvate oxidation
⫸ What inhibits pyruvate dehydrogenase? Answer: high levels of ATP,
acetyl CoA , and NADH
, ⫸ What stimulates pyruvate dehydrogenase? Answer: high levels of
AMP, coenzyme A, and NAD+
⫸ Where does the citric acid cycle occur? Answer: mitochondrial
matrix
⫸ What enters the citric acid cycle? Answer: 2 Acetyl CoA's
⫸ What does the citric acid cycle produce per turn? Answer: 1 ATP, 3
NADH, 1 FADH2, 2 CO2
⫸ How is pyruvate oxidation and the citric acid cycle regulated?
Answer: by concentrations of starting materials
⫸ where is most of glucose's original energy contained? Answer: in the
electrons that are transferred to NADH and FADH2
⫸ How many electrons does NADH and FADH2 each carry? Answer: 2
⫸ respiratory chain/electron transport chain (ETC) Answer: proteins
embedded within the inner mitochondrial membranes that facilitate a
series of redox reactions
