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. Increased urine acidity: Antidiuretic hormone (ADH) primarily affects water reabsorption in the kidneys, not urine acidity. It does not have a direct effect on the acidity of the urine.
B. Increased urine volume: ADH works to conserve water by increasing water reabsorption in the kidneys, which decreases urine volume.
C. Increased urine salinity: While ADH does increase water reabsorption, which could concentrate the urine, its direct action is on water retention, not specifically on increasing urine salinity.
D. Decreased urine volume: ADH promotes water reabsorption in the kidneys, leading to decreased urine output. This is the direct and correct result of ADH action.
Correct Answer is D
Explanation
A. Metabolic water; cutaneous transpiration: Metabolic water refers to the water produced during metabolic processes within the body. However, most body water intake comes from drinking fluids, not metabolic water.
B. Drinking; cutaneous transpiration and expired air: While drinking is indeed the main source of water intake, the greatest loss of water from the body is through urine, not cutaneous transpiration and expired air.
C. Drinking; radiation: While drinking is the primary source of water intake, radiation is not a significant way the body loses water.
D. Drinking; urine: Drinking fluids is the main source of water intake, and urine excretion is the primary way the body loses water.
