Homework Answers
Answer :- correct option is :-
Protonswould not moved from the matrix to the intermebrane space and so ATP synthase would not be activated.
Explanation:- In cellular respiration the electrons moves along the series of membrane proteins through the electron transport system and leads the transport of protons from the matrix into the intermembrane space.
This creats the proton electrochemical gradient which activates ATP synthase and power the synthesis of ATP.

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...

In mitochondria, a proton gradient is established by the movement of electrons through the electron transport chain. Protons are moved to the intermembrane space against the concentration gradient and the flow back to the matrix via facilitated diffusion using the ATP synthase. Describe how this proton flow contributes to ATP synthesis and the role played by aspartic acid in this process.

In cellular respiration, as a result of the electron transport chain, a proton gradient is established. Where in the cell are the protons concentrated? In the intermembrane space, between the inner and outer membranes of the mitochondrion Between the outer membranes of the mitochondrion and the plasma membrane Between the plasma membrane and the cell wall Between the plasma membrane and the extracellular matrix In the inner membrane of the mitochondrion
