Answer 1

Que: what is the immediate consequences after electron pass through ion pump protein?

• During the electron transport or pass through the ion pump protein . It will transfer two electron from NADH and it's generate NAD molecules. During this process transport of electrons is oriented with H+ ion release and uptake.
• This 2 hydrogen ions will force out by ion pump in inner membrane to outer membrane.
• After next process of electrons transport through ion pump received those respective two electrones.

Que: How is the proton concentration gradient create inside and outside of mitochondrial inner membrane?

• The proton pump uses energy source to transport proton (H+) from matrix to Mitochondrial inner membrane.
• During this active pump will generate proton concentration gradient across the inner membrane due to presence of more protons outside the matrix than inside ( higher to lower energy level) some energy used for H+ ions pump and generate proton gradient across inner membrane.
• The electron are passed to oxygen which combined with proton to form water.

Que: ATP is produced due to the electron transport or due to the proton gradients.

• ATP is produced due to the proton gradients.

Que: How many ATP can be produced when every three hydrogen ions pass through ATP synthase?

• 1 ATP can be produced when three hydrogen ions pass through ATP synthase. While every three hydrogen ions pass through the membrane it will generate another ATP molecules which is six ATP.
