Question

1. which evidence could best support the claim that aerobic respiration is more efficient than anaerobic respiration?

respiration
both processes use mitochondria to produce energy.
anaerobic respiration causes more cell growth.
aerobic respiration produces more atp molecules per glucose.
aerobic respiration requires more oxygen that anaerobic respiration.
a.
b.
c.
d.

Explanation:

Step1: Recall aerobic and anaerobic respiration facts

Aerobic respiration uses oxygen and occurs in mitochondria, producing a large amount of ATP per glucose molecule. Anaerobic respiration occurs without oxygen and produces less ATP and may cause cell - growth issues in some cases.

Step2: Analyze each option

Option a: Both processes use mitochondria is incorrect as anaerobic respiration does not use mitochondria. Option b: Anaerobic respiration causes more cell growth is incorrect as anaerobic respiration can lead to the build - up of lactic acid or ethanol which can be harmful to cells in the long run. Option c: Aerobic respiration produces more ATP per glucose molecule is correct as aerobic respiration produces up to 38 ATP per glucose molecule while anaerobic respiration produces only 2 ATP per glucose molecule. Option d: Anaerobic respiration requires more oxygen is incorrect as anaerobic respiration occurs in the absence of oxygen.

Answer:

c. Aerobic respiration produces more ATP per glucose molecule.
