Question

1. according to your notes, muscle force depends on the number of ......

fibers stimulated.

amount of atp available.

speed of the reflex.

calcium ions released.

Explanation:

Muscle force generation is related to the number of muscle fibers that are stimulated. When more muscle fibers are activated (stimulated), the overall force produced by the muscle increases. ATP is for energy supply, reflex speed is about neural response time, and calcium ions are involved in muscle contraction mechanism but the key factor here regarding "number" is fibers stimulated.

Answer:

fibers stimulated.
