Question

Which of the following releases energy?

1. Nutrients entering a cell through the cell membrane
2. Adding an additional phosphate group to an ADP molecule
3. Building sugar or starch molecules for long-term energy storage
4. Removing a phosphate group from an ATP molecule

Answer 1

4. when a high energy phosphate bond is cleaved, there is a release of energy.Hydrolysis of ATP (which is using H2O to break open the phosphate bonds) produces around -35.7KJ/mol of ATP.

Answer 2

thanks!

Answer 3

4. Removing a phosphate group from an ATP molecule

All other process will need energy

Answer 4
