Glycolysis and aerobic respiration collectively produce up to ___________ ATP per glucose, whereas anaerobic fermentation produces __________________.
32;36
32;2
2; about the same, varying from one tissue to another
32; none
36; about the same, varying from one tissue to another
The Correct Answer is B
A. 32; 36. Aerobic respiration, including glycolysis, citric acid cycle, and oxidative phosphorylation, can produce up to 36 ATP per glucose. Anaerobic fermentation, however, only produces 2 ATP per glucose, not 36.
B. 32; 2. Aerobic respiration, including glycolysis, citric acid cycle, and oxidative phosphorylation, typically produces up to 36 ATP per glucose, though 32 is a commonly cited figure depending on the specifics of the process. Anaerobic fermentation produces 2 ATP per glucose. The discrepancy in ATP production is due to differences in efficiency and accounting for the energy yield in different conditions.
C. 2; about the same, varying from one tissue to another. Anaerobic fermentation produces 2 ATP per glucose, but aerobic respiration (including glycolysis and subsequent steps) produces up to 36 ATP. The "about the same" part is not accurate for aerobic versus anaerobic processes.
D. 32; none. Anaerobic fermentation does produce ATP, specifically 2 ATP per glucose. Aerobic respiration produces up to 36 ATP per glucose.
E. 36; about the same, varying from one tissue to another. Aerobic respiration can produce up to 36 ATP per glucose, and anaerobic fermentation produces only 2 ATP per glucose. The ATP production difference is significant and not “about the same.”

Correct Answer is D
Explanation
A. Estrogen is a hormone involved in the regulation of the menstrual cycle and pregnancy, but it is not the hormone detected by pregnancy tests.
B. Luteinizing hormone (LH) surges just before ovulation but is not the hormone detected by pregnancy tests.
C. Progesterone supports pregnancy by maintaining the uterine lining, but it is not the hormone detected by pregnancy tests.
D. Human chorionic gonadotropin (hCG) is the hormone produced by the placenta shortly after implantation, and it is the hormone detected by pregnancy tests.
Correct Answer is C
Explanation
A. Lactose; lactase: Lactase is the enzyme that breaks down lactose, not the other way around.
B. Lipases; micelles: Lipases break down lipids (fats) into fatty acids and glycerol, not micelles. Micelles are formed as part of the digestion process but are not the substrate for lipases.
C. Peptidases; proteins: Peptidases (or proteases) break down proteins into smaller peptides and amino acids. This is the correct answer.
D. Lactase; glucose: Lactase breaks down lactose into glucose and galactose, not just glucose.
