Question

a cheetah on seeing a prey moves towards him at a very high speed. what causes the movement of his muscle? how does the chemistry of cellular component of muscle changes during this event?​

Answer 1

The photo-receptors present in the tiger that help him to sense its victim quickly.

Explanation:

• The signals are then sent to the nervous system and carried by neurons.
• The special proteins actin and myosin are present in its muscle that changes the orientation of its cells.
• The regular contraction and relaxation of the muscles help quick muscle movement and let the tiger take action quickly.

Answer 2

Answer:

Nerve Impulse and Structure of Special Proteins in Muscle Fibre.

Explanation:

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.
