Question

What are two differences between the process of chemiosmosis that occurs in chloroplasts and mitochondria?

Answer 1

Chloroplasts and mitochondria differ in terms of accessory pigments and the use of chemiosmosis in different processes.

Step-by-step explanation:

There are several differences between the process of chemiosmosis that occurs in chloroplasts and mitochondria:

1. Chloroplasts contain accessory pigments in thylakoids, which form grana and a stroma, whereas mitochondria have inner folds called cristae.
2. Chloroplasts use chemiosmosis in the light reactions of photosynthesis to harness the energy of sunlight in a process called photophosphorylation, while mitochondria use chemiosmosis in oxidative phosphorylation to produce ATP during cellular respiration.
