a blood agar plate contains sheep red blood cells Proton gra

Proton gradients and ATP production. What will be the impact of adding a proton ion phone (a proton channel) to the membrane of E coli? There will be an increase in growth rate if it is growing

Solution

Answer is C. In E. coli, which is a prokaryote does not possess mitochondria for energy production. So it can utilise its membrane for the production of proton motive force and energy. This energy is utilized for the cell division, growth and motility. In E. Coli, dyring aerobic respiration, the proton motive force generated due to pumping of protons fromcytosol to periplasmic space. This leads to proton motive force and consquently energy generation. When Ion channel incorporated in the E. Coli membrane, it loose its proton motive force and also energy and finally cell growth and division stops
