Chapter 3- Energy Systems

Question 1

Anaerobic glycolysis

Answer 1

Doesn’t require oxygen therefore glycogen isn’t completely broken down
Incomplete breakdown of carbs
Energy is obtained from breakdown of glycogen
Pyrrhic acid is formed

Question 2

Aerobic system

Answer 2

Requires oxygen
Most effective system
Lasts the longest
Also known as aerobic glycolysis- breakdown of glucose while oxygen is present

Question 3

Fuel

Answer 3

ATP- PC- carbs
Anaerobic glycolysis- sugar
Aerobic- protein fat carbs

Question 4

Rate of atp resynthesis

Answer 4

ATP- PC- very fast
Anaerobic glycolysis- fast
Aerobic- moderate to slow

Question 5

No of chemical reactions

Answer 5

ATP- PC- minimal
Anaerobic glycolysis- few
Aerobic- multiple

Question 6

Power/ intensity

Answer 6

ATP- PC- very high
Anaerobic glycolysis- high
Aerobic- sub maximal

Question 7

Amount of ate produced

Answer 7

ATP- PC- 1
Anaerobic glycolysis- 2
Aerobic- sugar 38. Fat 100+

Question 8

Duration/ capacity

Answer 8

ATP- PC- 0-10 sec
Anaerobic glycolysis- 10-75 sec
Aerobic- 1-1.5 minutes

Question 9

Type of activity

Answer 9

ATP- PC- 100 metre sprint
Anaerobic glycolysis- 50 metre freestyle sprint
Aerobic- 5 km run

Question 10

Difference between anaerobic and aerobic glycolysis

Answer 10

Diagram

Question 11

Lactate Inflection point

Answer 11

The moment when the body is unable to prevent accumulation of the hydrogen ions associated with the conversion of lactic acid to lactate in the working muscles

Question 12

Steady state

Answer 12

When oxygen demand equals oxygen supply

Question 13

ATP-PC

Answer 13

First energy system to be used
Quickest to break down PC to make ATP
Stored in muscle cells
Doesn’t require oxygen
