Question

Which of the following membrane activities require energy from ATP hydrolysis?

Answer 1

Answer:

C) Na+ ions moving out of the cell

Explanation:

• Movement of Na+ ions out of the cell requires hydrolysis of ATP, a process called active transport.
• Active transport involves movement of materials against a concentration gradient using energy from the hydrolysis of ATP.
• Active transport system uses energy in the form of ATP to move substances such as ions into the cell or out of the cell.
