electron transport chain

Question 1

where is the highest concentration of hydrogen ion (H+) is located?

Answer 1

intermembrane space

Question 2

how do the hydrogen ions reach the intermembrane space?

Answer 2

They travel through embedded protein channels.

Question 3

Explain why energy is required to move the hydrogen ions across the membrane in the direction indicated.

Answer 3

Energy is needed as the hydrogen ions are being pumped against the concentration gradient.

Question 4

What molecules carry these high potential energy electrons?

Answer 4

NADH and FADH2

Question 5

When the electrons are released from the electron acceptor molecules, what else is produced?

Answer 5

Hydrogen ions are also produced.

Question 6

Is the release of an electron from one of these electron acceptor molecules oxidation or reduction?

Answer 6

oxidation

Question 7

What molecule is the final electron acceptor after the electron has moved through the electron transport chain?

Answer 7

Oxygen is the final electron acceptor.

Question 8

What compound is formed as a final product of the electron transport chain?

Answer 8

Water is formed when oxygen picks up the electrons from the electron transport chain.

Question 9

Is any ATP produced or used in the electron transport chain?

Answer 9

no
