When ATP in the sarcoplasm is exhausted, the muscle must rely on creatin phosphate. What is the function of this chemical element?

• Increase Ca²⁺

  ^{in muscle}

• Decrease Ca²⁺ in muscle

• A.                Decrease ATP from ADP for contraction

•    Produce more ATP from ADP for contraction

  Immediately following strenuous and vigorous exercise, which of the following is most likely to occur? (U)

• A.                blood will be rapidly diverted to the digestive organ

• the skin will be cold

•                 capillaries of the active muscles will be engorged with blood  

• A.                blood flow to the kidneys quickly increases

Aerobic respiration  (U)

• results in the breakdown of glucose to yield ATP and lactic acid

• is much less efficient than anaerobic respiration

• can use fatty acids and amino acids to generate ATP

• can occur much faster than anaerobic respiration

A high-energy molecule that can be quickly used to produce ATP is (R)

• creatine phosphate

• glucose

• carbon dioxide

• lactic acid
