9) Energy for muscle contractions comes from all the following EXCEPT:

A. Amino acids stored in the liver
B. Initially, a small amount of ATP found in muscles
C. The breakdown of creatine phosphate
D. Aerobic respiration in muscle cell mitochondria



Answer :

GinnyAnswer

Final answer:

Muscle contraction energy is sourced from ATP, creatine phosphate, and aerobic respiration.


Explanation:

The sources of energy for muscle contractions include:

  1. Initial small amount of ATP found in muscles
  2. Breakdown of creatine phosphate
  3. Aerobic respiration in muscle cell mitochondria

The energy for muscle contractions does not come from amino acids stored in the liver.

During muscle contractions, ATP is the immediate source of energy, with creatine phosphate and aerobic respiration also playing essential roles.
