The Energy Systems

Question 1

What enzyme breaks down Creatine Phosphate in the ATP-PC system?

Answer 1

Creatine Kinase

Question 2

What does creatine phosphate break down into?

Answer 2

Creatine, Phosphate and energy

Question 3

What is the equation for Adenosine Triphosphate (ATP)?

Answer 3

Phosphate + Adenosine Diphosphate and energy

Question 4

What is the full ATP-PC system ?

Answer 4

Creatine Phosphate is broken down by Creatine Kinase into Creatine, Phosphate and energy. The energy and Phosphate react with Adenosine Diphosphate to make Adenosine Triphosphate

Question 5

Positives of the ATP-PC system (4)

Answer 5

• no fatiguing by-products
• energy source already in the muscles
• does not require oxygen
• Very fast reaction

Question 6

Negatives of the ATP-PC system (3)

Answer 6

• only lasts 10 seconds
• has a resynthesise ratio of 1:1
• Limited CP stores

Question 7

What type of activities is the ATP-PC system most predominant in?

Answer 7

Short and High intensity activities

Question 8

Where does the ATP-PC system take place?

Answer 8

Sarcoplasm

Question 9

Which energy system lasts up to ten seconds?

Answer 9

ATP-PC system

Question 10

Where is the Lactic acid system located?

Answer 10

The Sarcoplasm of the muscle

Question 11

What enzyme breaks down Glycogen into Glucose?

Answer 11

Glycogen Phosphorylase (GPP)

Question 12

How much ATP does the lactic acid system produce?

Answer 12

2 ATP

Question 13

What is glucose broken down into and by what enzyme?

Answer 13

Pyruvic acid, Phosphofructokinase (PFK)

Question 14

Why does pyruvic acid turn into lactic acid?

Answer 14

There isn’t enough oxygen

Question 15

What enzyme breaks down pyruvuc acid into lactic acid?

Answer 15

Lactate Dehydrogonase (LDH)

Question 16

Positives of the lactic acid system (4)

Answer 16

• Fast reaction speed
• Does not require oxygen
• moderate number ofchemical reactions
• lasts up to 2/3 minutes

Question 17

negatives of the lactic acid system (2)

Answer 17

• duration is relative to the intensity

- releases lactic acid which lowers the muscle ph. Causing muscle fatigue

Question 18

What intensity is the Aerobic system most predominant at?

Answer 18

Low intensity

Question 19

What is the Glycolysis reactions in the Aerobic System (including enzymes and ATP)

Answer 19

Glycogen (Glucose Phosphorylase) >
Glucose (Phosphofructokinase) >
Pyruvic acid + 2 ATP

Question 20

What is the name of the process for the Lactic Acid energy system

Answer 20

Anaerobic Glycolysis

Question 21

The Krebs cycle part which gives off ATP and how much

Answer 21

Acetyl Co-enzyme > Oxyalocetic acid > Citric acid > Co2 + ATP + Acetyl Co-enzyme

Question 22

The route of Pyrucvic acid to NADH in the Aerobic System

Answer 22

Pyruvic acid > Acetyl Co-enzyme > NAD (+ H) > NADH

Question 23

The ETC cycle in the Aerobic System

Answer 23

NADH > H20 > Oxygen + 32 ATP

Question 24

Positives of the Aerobic system (3)

Answer 24

• Very efficient resynthesis rate 1:32
• No fatigueing by-products
• Can use fats as a source

Question 25

Negatives of the Aerobic System (2)

Answer 25

• Only during low-moderate intensity

- Takes much longer

Question 26

What is the Threshold point?

Answer 26

the point at which energy systems switch over being the most predominant

Question 27

What is the O2 deficit?

Answer 27

The accumulation in difference between the O2 requirement and O2 consumption

Question 28

What two components is EPOC broken down into?

Answer 28

Fast and a slow component

Question 29

What is EPOC

Answer 29

Excess post excercise oxygen consumption
