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

Explanation

Nerve Impulse and Structure of Special Proteins in Muscle Fibre, On seeing the prey, an impulse is sent from the brain to the muscles in it.s limbs so that the cheetah can run towards the prey. Muscles have special proteins that change both their shape and their arrangement in the cells, new arrangement of the proteins give different forms to the muscle cells, i.e. Shorter or Larger form.
Therefore, the cheetah is able to run after the prey due to the arrangement of cellular components (proteins) in the muscles.
