Question

question 81

a during electron transport.
b during glycolysis.
c during photosynthesis.
d during the citric acid cycle.
e in the cytoplasm.
question 82
a body mass index will likely be overestimated in.
a an office worker.
b an athlete.
c a teacher.
d a banker.
e a student.

Explanation:

• Question 81: Aerobic respiration has three main stages - glycolysis, citric acid cycle, and electron transport chain. Glycolysis produces a small amount of ATP (net 2 ATP per glucose). The citric acid cycle also produces a limited amount (about 2 ATP per glucose). Photosynthesis is for energy capture in plants (not relevant to ATP production in aerobic respiration of animals etc. in this context). The electron transport chain, through oxidative phosphorylation, produces the majority of ATP (about 28 - 32 ATP per glucose).
• Question 82: Body Mass Index (BMI) is calculated as \(BMI=\frac{weight\ (kg)}{height^{2}(m^{2})}\). Athletes often have more muscle mass. Muscle is denser than fat. Since BMI does not distinguish between muscle and fat mass, an athlete with a high - muscle mass (but low - fat mass) will have a higher weight - to - height ratio (higher BMI) compared to a non - athlete with the same fat - mass - to - height ratio. Office workers, teachers, bankers, and students (in general) do not have the same level of muscle - mass - to - body - weight ratio as athletes on average.

Answer:

Question 81: A. during electron transport.
Question 82: B. an athlete.
