The Function of H? Ions in the Body Is

Question

The function of H? ions in the body is
A) maintenance of the cell membrane
B) conduction of nerve impulses
C) function of cellular enzymes
D) stimulation of muscle contraction

Accepted Answer

H+ ions play an important role in activating enzymes in the body by causing a change in the shape of the active site that allows it to bind to the substrate. This is necessary for many biological processes such as digestion, cellular respiration, and DNA replication. H+ ions are also involved in pH regulation and maintaining the acid-base balance of the body, which is crucial for proper functioning of the cells and enzymes. Therefore, option C is the correct choice. Options A, B, and D are not directly related to the function of H+ ions.
