Question

What function is enabled by the respiratory membrane in proteobacteria

Answer 1

Ans. The function of respiratory membrane in proteobacteria (or, in any (Gram-ngative) bacteria, if present) is similar to that of mitochondria in eukaryotes.

The respiratory membrane is an inward invagination of bacteria cell membrane where the electron transport chain components are located. The protons are pumped out across the respiratory membrane into periplasmic space during cellular reparation or ETC. When the protons travel back along its gradient into the respiratory membrane, ATP is synthesized.

# Therefore, the respiratory membrane of proteobacteria enables the bacteria to do cellular respiration and produces larger amount of ATP during cellular respiration like mitochondrial respiration.
