Compared to aerobic respiration, anaerobic respiration
a
does not require oxygen and produces oxygen and glucose as forms of stored energy that are utilized by the cell.
b
does not produce as much ATP and comes into action as an energy backup for aerobic organisms.
c
requires oxygen and can produce products such as lactic acid or alcohol.
d
produces 38 ATP molecules per reaction and generates 70% more energy.
b
does not produce as much ATP and comes into action as an energy backup for aerobic organisms.
b
does not produce as much ATP and comes into action as an energy backup for aerobic organisms.
The correct answer is B: Anaerobic respiration does not produce as much ATP and comes into action as an energy backup for aerobic organisms.
To arrive at this answer, let's break down the options and discuss how to find the correct one:
Option A states that anaerobic respiration does not require oxygen and produces oxygen and glucose as forms of stored energy that are utilized by the cell. This statement is incorrect because anaerobic respiration specifically does not require oxygen and does not produce oxygen.
Option B states that anaerobic respiration does not produce as much ATP and comes into action as an energy backup for aerobic organisms. This statement is correct. Anaerobic respiration is less efficient than aerobic respiration and occurs when there is not enough oxygen available for aerobic respiration to take place. It serves as a backup process to provide energy when oxygen levels are low.
Option C states that anaerobic respiration requires oxygen and can produce products such as lactic acid or alcohol. This statement is incorrect. Anaerobic respiration occurs in the absence of oxygen, and while it can produce lactic acid or alcohol depending on the organism, it does not require oxygen.
Option D states that anaerobic respiration produces 38 ATP molecules per reaction and generates 70% more energy. This statement is incorrect. Anaerobic respiration produces much less ATP compared to aerobic respiration. Aerobic respiration produces around 38 ATP molecules per glucose molecule, while anaerobic respiration produces far fewer ATP molecules.
Therefore, the correct answer is B: Anaerobic respiration does not produce as much ATP and comes into action as an energy backup for aerobic organisms.
