Detailed explanation-1: -Electrons are passed from one member of the transport chain to another in a series of redox reactions. Energy released in these reactions is captured as a proton gradient, which is then used to make ATP in a process called chemiosmosis.

Detailed explanation-2: -The actual production of ATP in cellular respiration takes place through the process of chemiosmosis (see Chapter 4). Chemiosmosis involves the pumping of protons through special channels in the membranes of mitochondria from the inner to the outer compartment.

Detailed explanation-3: -Yes, chemiosmosis does occur in photosynthesis and respiration. Q. Based on chemiosmosis, hydrogen ions accumulate in the of the mitochondrion to create a large electrochemical gradient for aerobic cellular respiration.

Detailed explanation-4: -The process of pumping protons across the membrane to generate the proton gradient is called chemiosmosis. Chemiosmosis is driven by the flow of electrons down the electron transport chain, a series of protein complexes in the membrane that forms an electron bucket brigade.
