◉ false
Answer: T/F a biochemical metabolic pathway is a single reaction
that converts starting material into products
◉ false
Answer: T/F three ATP molecules are used in the energy-investing
stage of glycolysis
◉ false
Answer: T/F the citric acid cycle occurs in the absence of oxygen
◉ true
Answer: T/F the beta-oxidation pathway degrades both even-
numbered and odd-numbered fatty acids
,◉ A. 2 ATP produced
Answer: in converting glucose to pyruvate, how many ATP or NADH
are produced (or required) in the 1, 3-bisphosphoglycerate to 3-
phosphoglycerate step in glycolysis?
A. 2 ATP produced
B. 1 ATP required
C. 1 NADH produced
D. 2 NADH and 1 ATP produced
E. none of the above
◉ C. 2 ATP produced
Answer: in converting glucose to pyruvate, how many ATP or NADH
are produced (or required) in the phosphoenolpyruvate to pyruvate
step in glycolysis?
A. 1 ATP required
B. 1 ATP produced
C. 2 ATP produced
D. 2 ATP required
E. none of the above
◉ A. glucose
Answer: what is the primary reactant of glycolysis?
A. glucose
, B. glucose-6-phosphate
C. fructose
D. fructose-6-phosphate
E. hexokinase
◉ A. hexokinase
Answer: in glycolysis, when glucose enters a cell, it is immediately
phosphorylated to form glucose-6-phosphate. the phosphate donor
in this reaction is ATP, and the enzyme is _____
A. hexokinase
B. aldolase
C. CoA
D. phosphohexose isomerase
E. none of the above
◉ A. substrate-level phosphorylation
Answer: in the last reaction of glycolysis, ATP is formed by the direct
transfer of a phosphate group from a metabolite to ADP. this process
is referred to as:
A. substrate-level phosphorylation
B. protein phosphorylation
C. lipid phosphorylation
D. isomerization
