Question

What happens to the concentration of H⁺ in the intermembrane space and the matrix as electrons move down the ETC?

Answer 1

Glucose molecule underwent 3 cycles of reactions,they are

*Glycolysis:2 Atp"s are relaeased

*kreb's cycle:2 Atp's are released

*Electron transport chain:34 Atps are released.

Glycolysis takes place in cytoplasm of the cell,where as Krebs and ETC takes places in the inner membrane of mitochondria.Mitochondira is known as the power house of cell,why beacuse repiration of cells and energy release takes place in the mitochondira matrix.the releases enegy is stored in the form of ATP.Mitochondira had two membranes they are:

• outer membrane
• inner membrane:in this folding like structure apperas its known as Cristae,catalyst like enzymes and proteins are there in this membrane
• for to seggrate both membranes inter membrane space is present,fluid is present in this.

in mitochonidral matrix

NADH---->NAD+ ++ H

H---> e- + H+

IN THIS BOTH OXIDATION AND REDUCTION TAKES PLACE

NADH----->NAD+ SO H+ H+ H+ H+ RELEASES.

SO IN ETC H+ IONS RELEASED OUT OF THE INTERMEMBRANE SPACE,SO AT THAT TIME CONCENTRATION OF H+ IONS INCREASED IN THAT PLACE.SO THEY START MOVING TO MATRIX OF THE MITOCONDIRA.

FOR EXAMPLE ONE HUNDRED SEATED FUNCTION HALL IS THERE,BUT 120 PEOPLES ARE CAME THERE IS NO PLACE THAT MEANS PEOPLE ARE CONCENTRATED AT ONE PLACE.SO SOME PEOPLE CAME BACK OUTSIDE OF THE HALL.WHENEVER CONCENTRATION OF PEOPLES DECREASES THESE PEOPLE MAY GO INTO THAT AREA.
