Question

question 23 what is oxygen needed for during aerobic cellular respiration? a oxygen is the final acceptor of the moving electrons. b oxygen is the \fuel\ that is \burned\ by cells. c oxygen functions as a cofactor in several enzymatic reactions. d oxygen is needed for the lungs to function question 24 the final product of fermentation in yeast is. a pyruvate. b glucose. c lactic acid. d acetic acid. e alcohol.

Explanation:

In aerobic cellular respiration, oxygen serves as the final electron - acceptor in the electron transport chain, facilitating the production of a large amount of ATP. In yeast fermentation, glucose is broken down into pyruvate first, and then pyruvate is converted into alcohol and carbon dioxide as the final products.

Answer:

Question 23: A. Oxygen is the final acceptor of the moving electrons.
Question 24: E. alcohol.
