20s - Q3
Fermentation in muscle cells produces a waste product called ____________. The buildup of this product makes you feel fatigue and soreness.
glucose
carbon dioxide
ethanol
lactic acid
20s - Q4
Which enzyme of the citric acid cycle is membrane-bound?
Succinyl-CoA synthetase
Succinate dehydrogenase
Isocitrate dehydrogenase
None of the Krebs cycle enzymes are membrane-bound
20s - Q5
True or False. Glycolysis is a biochemical pathway that releases energy in glucose to form ADP from ATP and inorganic phosphate, NAD+ from NADH, and pyruvate.
False
True
20s - Q6
What is a disadvantage of fermentation as a process?
It only produces 2 ATP
It produces too much ATP
It occurs in the absence of oxygen
It is only for quick bursts of energy
20s - Q7
What enzyme in the Electron Transport Chain is responsible for generating the ATP molecules?
ATPase
Hexokinase
NADH dehydrogenase
ATP synthase
20s - Q8
How are lactic acid and alcoholic fermentation similar?
They have the same reactants
They both require oxygen
They have the same products
They occur in the same organisms
20s - Q9
After the citric acid cycle only a small portion of the energy of glucose has been converted to ATP. At this point the majority of usable energy is contained in
Citrate
Acetyl-CoA
Carbon Dioxide
NADH and FADH2
20s - Q10
In a eukaryotic cell, most of the enzymes of the citric acid cycle are located in the
intermembrane space.
mitochondrial matrix.
inner mitochondrial membrane.
cytosol.
20s - Q11
Pyruvate, the end product of glycolysis, enters the citric acid cycle after it has been converted to
acetyl-CoA.
oxaloacetate.
lactic acid.
citrate.
20s - Q12
The citric acid cycle is involved in:
generation of energy from pyruvate.
degradation of amino acids.
synthesis of fatty acids.
all of the answers.
20s - Q13
True or False. The electron transport chain transfers energy from electrons in a series of coupled reactions that establish an electrochemical gradient across membranes.
True
False
20s - Q14
Which enzyme catalyzes the conversion of citrate to isocitrate?
Citrate synthase
Aldolase
Citrate isomerase
Aconitase
20s - Q15
