Question 18

Question

Compared to aerobic respiration, anaerobic respiration
a requires oxygen and can produce products such as lactic acid or alcohol.
• b produces 38 ATP molecules per reaction and generates 70% more energy.
C
does not produce as much ATP and comes into action as an energy backup for aerobic organisms
• d does not require oxygen and produces oxygen and glucose as forms of stored energy that are utilized by the cell.

Answer 1

The correct answer is c: does not produce as much ATP and comes into action as an energy backup for aerobic organisms.

Explanation:

• Anaerobic respiration occurs in the absence of oxygen and yields significantly less ATP compared to aerobic respiration.
• It is often utilized by organisms when oxygen is scarce or during intense exercise when aerobic pathways are insufficient to meet energy demands.
• While options a and d contain inaccuracies and misunderstandings about the processes, option b incorrectly states the ATP yield for anaerobic respiration.
