PLEASE HELP!

A student studying muscle contraction made the following hypothesis: "A muscle cell will contain a large number of ATP molecules, but other living body cells will have less ATP, or none at all."

The student's teacher stated that one part of the hypothesis was correct, and another part was incorrect.

Describe the role of ATP in the muscle cell.

The role of ATP is to provide energy for the cell to perform its function. Its made from cellular respiration. Muscles need a lot of ATP because they're always contracting and relaxing and they do happen to use more ATP than other body parts. However, if a cell has no ATP, its not able to perform specific tasks. It always has ATP on hand, but is not always used. The second part of the hypothesis is wrong!

Muscle cells produce a lot of ATP, which is the energy coin of the cell required for repeated muscle contraction, thereby the student is correct.

Adenosine triphosphate (ATP) is the energy coin that cells synthesize mainly in the mitochondria and then use to perform their metabolic functions (i.e., movement, growth, differentiation, etc).

Cellular respiration refers to the metabolic pathways by which aerobic cells can produce ATP by using the energy from chemical bonds of foods and oxygen.

Muscle cells can produce ATP by both cellular respiration and acid lactic fermentation.

In muscle cells, ATP is used for two fundamental processes: active transport of calcium (Ca2+) ions and preparing myosin motor proteins for binding with actin, which is required for movement (muscle contraction).

In conclusion, muscle cells produce a lot of ATP, which is the energy coin of the cell required for repeated muscle contraction, thereby the student is correct.
