Energy Systems.

Question 1

What is the Aerobic Equation?

Answer 1

Glucose + Oxygen = Energy + Carbon Dioxide + Water.

Question 2

What is the Anaerobic Equation?

Answer 2

Glucose = Energy + Lactic Acid.

Question 3

Define ATP.

Answer 3

Adenosine Triphosphate.

Question 4

What is the equation for ATP?

Answer 4

A-P-P-P

Question 5

Define ADP.

Answer 5

Adenosine Diphosphate.

Question 6

List the 3 Phases of the Aerobic Energy System.

Answer 6

1. Glycolysis.
2. Krebs Cycle.
3. Electron Transport Chain.

Question 7

Explain the Glycolysis Phase of the Aerobic Energy System.

Answer 7

Glycogen reacts with Glycogen Phosphorylase to make Glucose.
Glucose and Phosphofructokinase react to make Pyruvic Acid + 2 ATP.

Question 8

Explain the Krebs Cycle Phase of the Aerobic Energy System.

Answer 8

First becoming Oxoloacetic Acid and then Citric Acid.
CO2 and Hydrogen are made along with 2 ATP.

Question 9

Explain the Electron Transport Chain of the Aerobic Energy System.

Answer 9

The hydrogen is split into positively charged H ions, and negatively charged electrons. Oxygen reacts with the H ions to make water. The electrons undergo a series of reactions which gives enough energy for 34 ATP.

Question 10

How long does the Aerobic Energy System last?

Answer 10

Hours.

Question 11

List the Advantages of the Aerobic Energy System.

Answer 11

Great for Low Intensity Work.
No Fatiguing by-products.
38 Total ATP.

Question 12

List the Disadvantages of Aerobic Energy System.

Answer 12

ATP is made slowly.
Recovery can take a Long Time.

Question 13

Explain the Lactate Anaerobic System.

Answer 13

Glycogen reacts with Glycogen Phosphorylase to make Glucose.
Glucose and Phosphofructokinase react to make Pyruvic Acid + 2 ATP.

Without enough O2, the Pyruvic Acid reacts with Lactate Dehydrogenase to make Lactic Acid.
With enough O2, the Pyruvic Acid makes Mitochondria.

Question 14

What does OBLA Stand for?

Answer 14

Onset of Blood Lactate Accumulation.

Question 15

Define OBLA.

Answer 15

The point at which lactic acid begins to rapidly accumulate in the blood.

Question 16

How long does the Lactate Anaerobic System last?

Answer 16

3 Minutes.

Question 17

List the Advantages of the Lactate Anaerobic System.

Answer 17

Great for High Intensity Work.
ATP produced at a Fast Rate.

Question 18

List the Disadvantages of the Lactate Anaerobic System.

Answer 18

Poor Yield - only 2 ATP.
Recovery can take up to an hour.
Harmful Lactic Acid is made.

Question 19

Explain the ATP-PC System.

Answer 19

Phosphocreatine is broken down by the enzyme creatine kinase into creatine, phosphate, and energy.

The phosphate and energy combine with an adenosine diphosphate [ADP] to make ATP.

This is called a coupled reaction.

Question 20

How long does the ATP-PC System last?

Answer 20

90 Seconds.

Question 21

List the Advantages of the ATP-PC System.

Answer 21

Great for high intensity wur.
ATP is produced at a fast rate.
No fatiguing by-products.
PC stores are quickly replenished after exhausion.

Question 22

List the Disadvantages of the ATP-PC System.

Answer 22

Limited duration and stores .
Yield is only 1 ATP per cycle.
