1. How ATP releases energy
2. Why cell activities (work) require ATP ​


Sagot :

Answer:

Think of it as the “energy currency” of the cell. If a cell needs to spend energy to accomplish a task, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate. The energy holding that phosphate molecule is now released and available to do work for the cell.

Explanation:

1.ATP can be used to store energy for future reactions or be withdrawn to pay for reactions when energy is required by the cell. ... When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP)

2.Functions of ATP in cells

Functions of ATP in cellsATP plays a critical role in the transport of macromolecules such as proteins and lipids into and out of the cell. The hydrolysis of ATP provides the required energy for active transport mechanisms to carry such molecules across a concentration gradient.
