Energy Systems

Question 1

Exercise Physiology is

Answer 1

The study of the cellular functions of the body during and after exercise - how bodies adapt and interact

Question 2

The cell

Answer 2

Most basic unit of life which produces ATP (adenosine triphosphate - currency for work)

Question 3

Predominate source for high energy is

Answer 3

ATP - Creatine phosphate

Question 4

Breakdown of sugars to pyruvate to generate ATP is

Answer 4

Glycolitic System

Question 5

3rd energy system (aerobic oxidation) is entered if

Answer 5

Oxygen is available at energy build up of pyruvate

Question 6

What happens at build up of pyruvate with no oxygen available

Answer 6

Body is working at high intensity - more energy is needed from glycolysis - needs to go through fermentation process

Question 7

Lactate is created by

Answer 7

Intense exercise

Question 8

Acid build up mainly caused by

Answer 8

Hydrolysis of ATP

Question 9

What makes muscle acidosis?

Answer 9

Hydrogen at lower intensity is buffered so Ph doesn’t get too low

Question 10

Gluconeogenesis is

Answer 10

Process of lactate converting back to glucose in the liver

Question 11

Lactate threshold or onset of blood lactate accumulation (OBLA)

Answer 11

The sudden rise or accumulation in lactate

Question 12

3rd energy system is known as

Answer 12

Aerobic pathway

Aerobic oxidation

Mitochondrial Respiration

Question 13

Powerhouse of the cell is

Answer 13

Mitochondria

Question 14

Build up of pyruvate is glycolosis

Answer 14

Crosses outer membrane of mitochondria, gets oxidized and converted to acetyl-CoA then enters Kreb Cycle

Question 15

For every 1 molecule of glucose there is __ to ATP

Answer 15

34-36

Question 16

3 Main Energy Systems

Answer 16

ATP/Creatine phosphate
Glycolisis
Aerobic Oxidation
