E.T.C (Electron Transport Chain)

Question 1

What is the ETC?

Answer 1

The ETC (Electron Transport Chain) is the third and final step of Cellular respiration.

Question 2

Where does the ETC take place?

Answer 2

The ETC is a series of proteins located on the mitochondrial membrane.

Question 3

how does the ETC work?

Answer 3

The ETC uses high energy electrons from the NADH and FADH2 by the Krebs Cycle to move H+ ions across the concentration gradient. These ions pass back down the concentration gradient through ATP synthase to form ATP.

Question 4

water is formed during the whole procces. how is it formed?

Answer 4

Oxygen receives electrons and H+ and produces a molecule of water.

Question 5

water is formed during the whole process. how is it formed?

Answer 5

Oxygen receives electrons and H+ and produces a molecule of water.

Question 6

in total, how much atp is made along the ETC.

Answer 6

The electron transport chain makes 34 ATP.

Question 7

The electron transport chain makes 34 ATP.
