Question

What is the difference between the electron transport reactions of mitochondria and the ones which take place in photosynthetic process?

Answer 1

The differences between the electron transport reactions of mitochondria and the ones which take place in photosynthetic process are

1. In mitochondria ATP synthase, the protons flow from the intermembrane space to the matrix whereas in photosynthetic process the protons flow from the thylakoid space into the stroma.

2. The end electron acceptor is oxygen in mitochondria and NADP in photosynthetic process.

3. The root source of electrons is generally glucose in mitochondria and the photolysis of water in case of photosynthesis.

4. The electron transport reactions of mitochondria produces carbon dioxide and photosynthesis produces oxygen.

4. The chemical reactions of the electron transport is as follows

 Mitochondria: C6H12O6+6O2 ---> 6CO2+6H2O+ATP

  Photosynthesis: 6CO2+6H2O --->C6H12O6+6O2

Hope this helps.
