Energy Metabolism

Question 1

What is the law of energy conservation

Answer 1

Energy can be converted from one form to another BUT cannot be created or destroyed

Question 2

Two types of metabolism

Answer 2

Catabolism

Anabolism

Question 3

Catabolism is

Answer 3

Biochemical reactions to break down large molecules to release energy

Question 4

Anabolism is

Answer 4

Biochemical reaction to synthesise new molecules by consuming energy

Question 5

Fatty acids go through? to produce?

Answer 5

Beta oxidation to produce Acetyl-CoA

Question 6

Glucose go through? to produce?

Answer 6

Glycolysis to produce Acetyl-CoA

Question 7

Amino acids go through? to produce?

Answer 7

Deamination to produce Acetyle_CoA

Question 8

The two energy-rich electron donor substances are produced

Answer 8

NADH

FADH2

Question 9

What is the Electron Transport Chain?

Answer 9

Set of reactions in the mitochondria

Question 10

NADH & FADH2 give energy to

Answer 10

the electron transport chain

Question 11

Electron transport train is an

Answer 11

oxidative process

Question 12

By-products of ETC

Answer 12

H2O and CO2

Question 13

In the presence of oxygen, the ETC produces how many ATP for carbohydrates

Answer 13

32 ATP

Question 14

ATP produced in glucose metabolism

Answer 14

Glycolysis - 2 ATP
Krebs - 2 ATP
ETC - 32 ATP

Total: 36 ATP

Question 15

Carrier molecules in the ETC are

Answer 15

Cytochromes

High to low energy state

Question 16

The process that synthesises ATP is called

Answer 16

Oxidative phosphorylation

Question 17

ATP produced by Fat Metabolism

Answer 17

Each 18C fatty acid yields 16 ATP

Therefore each molecule of lipid yields 3 x 146 = 438 ATP

Question 18

Protein is broken down for energy in

Answer 18

sustain, intense exercise

Starvation when carbohydrates and lips used up
