How are membranes important in the processes of photosynthesis and cellular respiration?

Answer 1

Teresa,

During both photosynthesis and cellular respiration cellular membranes are an important location where the electron transport chain occurs. During cellular respiration a process known as the Electron Transport chain occurs in the inner mitochondrial membranes. During this process the cell uses two electron carriers, FADH₂ and NADH, to create 32-34 ATPS molecules by giving the energy needed to turn ATP synthase for the process of chemiosmosis.

As for photosynthesis the thylakoid membrane, inside the Chloroplast, is the location of the Electron transport chain where ATP and NADPH (electron carrier)are made. These molecules are essential and give the energy needed later in the process to create glucose.
