the only energy source that can be used to directly power muscle activity
A
acetylcholine (Ach)
B
ATP
C
cross bridges
D
neuromuscular junction
Explanation: 

Detailed explanation-1: -Answer and Explanation: The only energy source that can be used to power muscle activity is ATP which stands for adenosine triphosphate. In order to generate ATP, a process known as cellular respiration occurs in the presence of oxygen.

Detailed explanation-2: -Adenosine triphosphate (ATP) is the sole fuel for muscle contraction. During near maximal intense exercise the muscle store of ATP will be depleted in < 1s, therefore, to maintain normal contractile function ATP must be continually resynthesized.

Detailed explanation-3: -The main types of “fuel” used by muscle for energy metabolism are glycogen, glucose, and free fatty acids [1-3]. The particular energy sources used by working muscle for aerobic metabolism depend upon a number of factors including the intensity, type, and duration of exercise, physical conditioning, and diet [4-6]:
