Question

In photosynthesis, what gives energy to the electron moving through the electron transport chain?

Water
NADPH
Light
ATP

Answer 1

In photosynthesis, LIGHT gives energy to the electron moving through the electron transport chain.

Photosynthesis is a process that involves light and using this light energy it produces ATP through conversion to chemical energy. The electron transport chain uses the energy to pump hydrogen ions across a membrane.

Answer 2

The correct option is ATP.
ATP is the energy currency of the cell, it is the major molecule which provides energy inside the living cells. During photosynthesis, the process requires the input of ATP to provide energy for the movement of electrons through the electron transport chain
