Explanation:
Detailed explanation-1: -ATP 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.
Detailed explanation-2: -Answer and Explanation: Cells use active transport to maintain homeostasis by pumping materials into or out of the cell to maintain a balance. For example, cells in the intestine actively pump glucose out of the lumen and into the blood. This helps keep the body fueled with glucose and maintains blood glucose levels.
