Photo Respiration:

=> It takes place in photosynthetic green cells.

=> It takes place only in the presence of light.

=> It involves chloroplast, peroxisome and mitochondria.

=> Substrate is glycolic acid.

=> It is not essential for survival.

=> No phosphorylation and yield of ATP.

=> Hydrogen peroxide is produced.

Dark Respiration:

=> It takes place in all living cells.

=> It takes place all the time.

=> It involves only mitochondria.

=> Substrate is carbohydrates, protein or fats.

=> Essential for survival.

=> Phosphorylation produces ATP energy.

=> Hydrogen peroxide is not produced.
