Electron Transport System and Chemiosmosis

Question 1

It is the partial partitions in a mitochondrion formed by infoldings of the inner membrane where electron transport chain is located.

Answer 1

Cristae

Question 2

An organelle in the cell that is also called the powerhouse where adenosine triphosphate is produced?

Answer 2

Mitochondria

Question 3

These are the two by-products of the citric acid cycle that are needed in the electron transport chain.

Answer 3

NADH and FADH2

Question 4

This is the energy used by the ATP synthase to convert ADP + inorganic phosphate to ATP.

Answer 4

Proton

Question 5

They are called as the energy currency of the cell and is produced in the mitochondria.

Answer 5

ATP

Question 6

Aside from the citric acid cycle, what other cellar respiration process happen inside the mitochondria?

Answer 6

Electron transport chain

Question 7

Where specifically does oxidative phosphorylation happen?

Answer 7

Inner membrane

Question 8

It is an energy-coupling mechanism that uses energy stored in the form of H+ gradient across a membrane to drive cellular work.

Answer 8

Chemiosmosis

Question 9

It is a molecular complex where ADP is converted into ATP with the help of protons from intermembrane space.

Answer 9

ATP synthase

Question 10

What would happen if the electron was not transferred from coenzyme Q to complex III?

Answer 10

Complex III won’t be charged thus it will not pump protons from mitochondrial membrane to intermembrane space.
