Homework Answers
Answer: Option(B) is correct
Explanation: In case of respiration the accumulation of proton is taking place in between the inner mitochondrial space. This accumulation of proton(Hydrogen ion concentration ) is responsible for the development of gradient which allow the movement of electrons from their higher concentration towards their lower concentration. Due to the presence of membrane protein known as ATP synthase there is process of generation of ATP through ADP + iP. The mechanism of generation of ATP in the cell organelle that is mitochondria is commonly called as oxidative phosphorylation. The membrane.

Oxidative phosphorylation is achieved through chemiosmotic coupling, which turns chemical energy into osmotic potential energy that is used to synthesize the energy “currency” of the cell (ATP). This process is divided into stage 1 (electron transport chain) and stage 2 (ATP synthase). Answer the following questions about each stage: In stage 1, what is the energy source used to form the proton gradient across the inner membrane and what is the principal carrier of this energy source? In stage 2,...

Which of the following is the best definition of oxidative phosphorylation? OA. Electrons are passed through a series of carriers to NAD+. B. A proton gradient created on one side of a membrane containing an electron transport chain, causes hydrogen ions to flow back through the membrane, through ATP synthase, releasing energy that is used to generate ATP. OC. ATP is directly transferred from a substrate to ADP. D. Electrons are passed through a series of carriers to an organic...

Which of the following statements about oxidative phosphorylation is true? a. Oxidative phosphorylation involves the activities of the electron transport chain and the ATP synthesizing machinery. b. The oxidation of NADH is the only way to form ATP. c. ATP is synthesized using the energy that is released when electrons and hydrogen are excreted outside of the cell. d. ATP synthesis occurs during oxidative phosphorylation directly by the reduction of electron carrier proteins in the cytoplasmic membrane.
