Question

The type of respiration that releases more energy is

• A. aerobic respiration
• B. anaerobic respiration in muscles
• C. both a and b will yield the same amount of energy
• D. anaerobic respiration carried out by yeast

Answer 1

The correct option is A

aerobic respiration

The correct option is A.

Explanation of the correct option:

• The type of respiration that occurs when oxygen is present is called aerobic respiration.
• Higher animals, especially mammals, have an aerobic mode of respiration.
• Aerobic respiration produces about 19 times more energy than anaerobic respiration per glucose molecule.

Explanation of the incorrect options:

Option B:

• Muscles use the anaerobic mode of respiration during exercise, producing less energy.

Option C:

• Aerobic respiration produces 38 ATP molecules, while anaerobic respiration produces 2 ATP molecules per molecule of glucose used.

Option D:

• During wine formation, yeast uses the anaerobic mode of respiration, producing less energy than aerobic organisms.

Therefore, more energy is released from aerobic respiration.
