Electrons flow through respiratory chain using ATP energy. |
Homework Answers
Chemiosmotic therory given by Peter Mitchell suggested that once there is gradient of H+ ions across the membrane then ions move or diffuse from high concentration to low concentration and while flowing down the conc gradient it pass through H+pump that is ATP synthase which cause phosphorylation of ADP +Pi------> ATP. This is called chemiosmotic theory.
Hope it's clear..thanks

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,...

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...
