Question

Does chemiosmosis occur in photosynthesis and cellular respiration?

Answer 1

Chemiosmosis:

1. Chemiosmosis is the passage of ions down an electrochemical gradient through a semipermeable membrane.
2. The enzyme that produces ATP via chemiosmosis is known as ATP synthase.

Photosynthesis:

1. The process through which green plants and certain other organisms convert light energy into chemical energy is known as photosynthesis.
2. Light energy is collected and utilized by green plants during photosynthesis to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic molecules.

Cellular respiration:

1. Cellular respiration is the mechanism through which sugar (glucose) is converted into energy within cells.
2. Chemiosmosis occurs in the chloroplasts during photosynthesis, and in the mitochondria during respiration.
3. Chemiosmosis is the method through which ATP is produced during cellular respiration.
4. Chemiosmosis is the movement of protons from the inner to the outer compartment of mitochondrial membranes via specific channels.

Yes, chemiosmosis does occur in photosynthesis and respiration.
