Question

Question 1 options:

A)

To give short bursts of energy to muscle cells

B)

To accept electrons, improving the efficiency of chemical reactions

C)

To donate electrons to all other particles within cellular respiration

D)

To act as a receptor for carbon dioxide molecules

Answer 1

The primary function of oxygen in aerobic respiration is:

B) To accept electrons, improving the efficiency of chemical reactions.

Oxygen serves as the final electron acceptor in the electron transport chain, which is a crucial step in aerobic respiration, leading to the production of ATP and water.
