Question

A cheetah, on seeing a prey, moves ttowards him at a very high speed. what causes the movement of his muscles? how does the chemistry of cellular components of muscles change during the event

Answer 1

Answer:

The changes in proteins

Explanation:

The muscle cells have special proteins which define the arrangement and shape of the cells.

When the cheetah sees the prey, the eyes (sensory neuron) detects, sends message to brain and then, brain sends an electrical impulse which travels neuron by neuron to the muscles. On reaching the muscle cells, it instructs the proteins to change the shape. This causes the muscles to contract or relax accordingly.
