Question

During photosynthesis, hydrogen ions are most directly used to _____________ in the chloroplast pictured above. A) make glucose B) make chlorophyll C) produce carbon dioxide D) drive the production of ATP

Answer 1

Answer: Option D. drive the production of ATP

Explanation:

Photosynthesis is defined as the process by which plants make their own food in the presence of light.

During the process of photosynthesis, light is trapped in chloroplast (chlorophyll) and at the same time in the presence of light the water molecules split into oxygen, hydrogen ions and free electrons.

The oxidation of water takes place in photosystem II and the hydrogen ions  released in the thylakoid lumen of chlorophyll and contribute to the movement of ions across a semipermeable that results into ATP synthesis.

Hence, the correct option is D.

Answer 2

The answer is D.
