Question

how do exo and endothermic reactions relate to the electron transportation in photosynthesis

Answer 1

Answer:

Photosynthesis is an endothermic reaction. The source of the energy for the formation of glucose is light (radiant energy), usually from the sun. Thus, green plants have the remarkable ability to trap the energy of sunlight and use that energy to produce glucose from carbon dioxide and water.

Answer 2

Answer:

The reverse reaction, the formation of one mole of water from hydrogen and oxygen (equation d), is exothermic and releases 285.8 kJ energy. ... Photosynthesis is an endothermic reaction. The source of the energy for the formation of glucose is light (radiant energy), usually from the sun.
