Answer #1

Hello,

14.Chemiosmosis hypothesis was given by Peter Mitchell.It explains the mechanism of membrane linked ATP synthesis.In chemiosmosis,the direct source of energy is energy released from movement of protons through ATP synthase,down their electrochemical gradient.In the region of only ATP synthase the inner membrane is permeable to the protons.To produce 1 ATP molecule 2 protons pass through F0 from the intermembrane space to the matrix down the electrochemical proton gradient.

15.During oxidative phosphorylation,oxygen that acts as terminal electron acceptor becomes reactive and combines with the proton to form water.So,option C is correct.

    Cellular respiration: The Electron Transport Chain The breakdown of glucose ends during the Krebs cydle; however, it is important to note that the energy previously contained in glucose is mostly stored in NADH and FADHz. In the last step of celular respiration, the high-energy electrons within NADH and FADH2 are passed within a set of proteins found in the inner membrane of the mitochondrion, collectively known as the electron transport chain. The electrons provide the energy to create ATP, which...
