Question

What happens to ATP after it binds to the protein?

Answer 1

Answer;

It changes to ADP

When ATP binds to the protein myosin it changes to ADP.

Explanation;

-ATP is an important molecules in muscle contraction without which the muscle would become rigid and fail to move.

-Proteins Myosin and actin are important in muscle contraction and relaxation. Myosin protein has two binding sites; one that binds actin protein and ATP molecules binds. At this site where ATP binds, enzymatic activity hydrolyzes ATP to ADP, releasing an inorganic phosphate molecule and energy.

Answer 2

Once ATP is used by the protein, the protein is able to change shape. So, for example: the cell membrane consists of many proteins, like integral and peripheral proteins. When the cell wants to carry out active transportation to transport substances against a concentration gradient into the cell, the carrier proteins on the membrane use ATP to change shape and transport the molecules into the cell through the gap in the proteins. And remember that energy is released when ATP is converted to Apple by ATPase enzymes.
