Muscle cells store enough atp and phosphocreatine for about of exercise.

The correct option is 15 seconds.

Explanation:

At the time of exercise, our muscles contract rapidly. The contraction of the muscles is a phenomenon which occurs from the energy source ATP.

There are four sources of obtaining ATP at the time of muscle contraction. One of this source is phosphocreatine.

The phosphocreatine can create ATP for 15 seconds after the muscles start to contract. Phosphocreatine has the ability to donate a phosphate group to ADP to produce ATP.

it's the cell cycle, but cytokines is when the cell divides.

theres 3 stages interphase,mitosis,and cytokines.

interphase prepares the cell for division.

mitosis is the process of dividing the cell,it has 4 parts interphase,anaphase,metaphase,and telophase.

lastly there's cytokines,that's when the cell divides into 2 daughter cells
