Detailed explanation-1: -Answer and Explanation: Generating ATP through chemiosmosis best describes a common process in the mechanisms by which cells capture and use free energy (b is correct).
Detailed explanation-2: -(D) Chemiosmosis is the chemical breakdown of water into hydrogen and oxygen ions at the final stage of the electron transport chain.
Detailed explanation-3: -Chemiosmosis involves the pumping of protons through special channels in the membranes of mitochondria from the inner to the outer compartment. The pumping establishes a proton (H+) gradient. After the gradient is established, protons diffuse down the gradient through a transport protein called ATP synthase.
Detailed explanation-4: -Which of the following best describes the process referred to as “chemiosmosis"? A concentration gradient of protons across the inner mitochondrial membrane is utilized to produce ATP.
