Question 6

A patient with a blood pH of $$7.1 is $$experiencing which condition, and what is the likely effect on enzyme activity?

Accepted Answer

Acidosis; decreased enzyme activity

Question 7

Which of the following best explains why water is considered a universal solvent in the human body?

Accepted Answer

Water dissolves and transports nutrients, gases, and metabolic wastes due to its polarity.

Question 8

Accepted Answer

High heat capacity

Question 11

Which of the following best describes the function of buffers in the human body?

Accepted Answer

Buffers prevent drastic changes in pH by releasing or binding $$H^+$$ ions.

Question 12

A person is experiencing muscle cramps due to low potassium ($$K^+) $$levels. Which class of inorganic compounds is most directly involved in this physiological function?
