Question

question 5
aerobic respiration:
a yields as many as 36 atp per glucose molecule metabolized
b produces atp molecules faster than anaerobic respiration
c occurs whether oxygen is present or not
d occurs entirely in the cytoplasm
e occurs in the ribosomes

Explanation:

• Option A: Aerobic respiration has a higher ATP yield. Glycolysis (cytoplasm) gives 2 ATP, the citric acid cycle (mitochondrial matrix) gives 2 ATP, and oxidative phosphorylation (inner mitochondrial membrane) gives about 32 - 34 ATP. In total, around 36 - 38 ATP per glucose molecule.
• Option B: Anaerobic respiration (like glycolysis alone in some cases) is faster as it has fewer steps. Aerobic respiration has more steps (glycolysis, citric acid cycle, oxidative phosphorylation) and takes more time.
• Option C: Aerobic respiration requires oxygen. Anaerobic respiration occurs without oxygen.
• Option D: Aerobic respiration occurs in the cytoplasm (glycolysis) and mitochondria (citric acid cycle, oxidative phosphorylation).
• Option E: Ribosomes are for protein synthesis, not respiration.

Answer:

A. yields as many as 36 ATP per glucose molecule metabolized
