Energy Carriers

Question 1

Oxidation

Answer 1

Loss of electrons.

Question 2

Reduction

Answer 2

Gain of electrons.

Question 3

ATP

Answer 3

-Adenosine triphosphate.
-Most important energy carrier.
-Formed by combining ADP with a phosphate.
-Anabolic reaction, requires energy and water molecule is released.
-Energy of ATP stored between second and third phosphates.
-A high energy molecule
-When third phosphate broken , ADP is formed.

Question 4

NAD+

Answer 4

Nicotinamide adenine dinucleotide.

Question 5

NADP+

Answer 5

Nicotinamide adenine dinucleotide phosphate.

Question 6

ADP + P + energy =

Answer 6

ATP + water.

Question 7

ATP + water =

Answer 7

ADP + P + energy.

Question 8

NAD+ and NADP+ are what?

Answer 8

High-energy electron and proton carriers
-NAD+ - Respiration
-NADP+ - Photosynthesis

Question 9

Respiration =

Answer 9

NAD+ + e- ➡️ NAD + e- ➡️ NAD- + H+ ➡️ NADH

-NADH uses electrons and hydrogen ions to make ATP.

Question 10

Photosynthesis =

Answer 10

NADP+ + e- ➡️ NADP + e- ➡️ NADP- + H+ ➡️ NADPH

-NADPH uses electrons and hydrogen ions to make glucose.

Question 11

ATP structure
