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 require oxygen and produces oxygen and glucose as forms of stored energy that are utilized by the cell. d does not produce as much ATP and comes into action as an energy backup for aerobic organisms.

Answer 1

The correct statement comparing anaerobic respiration to aerobic respiration is:

d does not produce as much ATP and comes into action as an energy backup for aerobic organisms.

Here's a brief explanation of each option:

a. False - Anaerobic respiration does not require oxygen. It typically produces products such as lactic acid (in animals) or alcohol (in yeast) instead of energy-rich molecules like glucose and oxygen.

b. False - Anaerobic respiration produces far fewer ATP molecules per reaction than aerobic respiration. Aerobic respiration can produce up to 38 ATP molecules per glucose, while anaerobic respiration yields only about 2 ATP molecules per glucose.

c. False - Anaerobic respiration does not produce oxygen or glucose; it occurs in the absence of oxygen and results in the conversion of glucose to lactic acid or ethanol, depending on the organism.

Therefore, option d is the only accurate statement regarding anaerobic respiration.
