Which of the following is a by-product of the ATP-PC system?
water
lactic acid
glycogen
There are no by-products of this system
Which system uses carbohydrates and fat as the fuel source?
Lactic Acid System
Aerobic System
ATP-PC System
None of these options
Which of these are by products of the Aerobic energy system?
There are no by-products
Carbon Dioxide
Water

Name an essential process in the body at rest that requires energy for maintenance (one word)
(a)
Energy production is the conversion of ____________
chemical energy to mechanical energy
mechanical energy to chemical energy
Correctly spell the full name of ATP
(a)
Name one of the three macronutrients that assist with the production of energy
(a)
When a muscle is stimulated to contract, what happens to provide energy?
You get a rush of blood to your body and are ready to go
All the bonds on the ATP molecule break apart giving energy to use
One of the high energy bonds in the ATP molecule breaks releasing energy to use
Your brain sends a message to your body to work harder and you get energy
Which of the three macronutrients is the most effective for energy production?
Fats
Carbohydrates
Proteins
Why are fats and proteins less effective than carbohydrates in creating energy?
They require larger amounts of oxygen to be broken down that could be used for fuelling muscles
They are harder to find in food
They break down too fast
They are used for body processes at rest rather than providing energy for movement
What is the name of the process where the body finds ways to replenish or recycle more ATP?
(a)
The anaerobic glycolysis system is another name for which energy system?
ATP-PC System
Lactic Acid System
Aerobic System
Alactacid System
What is the major difference in terms of energy resynthesis of the aerobic system?
resynthesis does not occur for this system
resynthesis happens very quickly, within 10 seconds
resynthesis occurs without oxygen present
resynthesis occurs with oxygen present
What is the fuel source of the ATP-PC system?
lactic acid
creatine phosphate
carbohydrates
water and carbon dioxide
What causes fatigue in the ATP-PC System?
Does not fatigue
Lactic Acid
Exhaustion of PC stores
Depletion of glucose stores
What is the duration of the Aerobic System?
One explosive movement
10 minutes
3-4 minutes
Unlimited whilst fuel source is available
After a marathon, how long do body glycogen stores need to fully recover?
6-8 hours
Up to 2 days (48hrs)
One week (7 days)
10-12 minutes
What is the duration of the Lactic Acid System?
Continual as long as there is food there for fuel
30-60 seconds
Around 3 minutes
10-12 minutes
Based on the primary energy system being used in a competitive 50m swim, how long is the rate of recovery.
10-30 minutes
30 mins to 2 hours
Up to 2 days
30 seconds to 2 minutes
A 'Jump Ball' in basketball engages which energy system?
ATP-PC
Lactic Acid
Aerobic
Alactacid System
The main energy system used in a triathlon is the (a) system.
'Hitting the wall' is the term used for the feeling when
When all energy systems are fatigued
The body switches from glycogen to fat as fuel
When PC stores are depleted
Lactic Acid is building up in the working muscles
In a 100m sprint, what by-product is created.
No by-products that cause the body to fatigue
Heat during muscular contraction
Glycogen
Water
Which energy system is being represented by the BLUE line?
ATP-PC System
Aerobic System
Alactacid System
Lactic Acid System
How many dash points are there in the 'Learn to' section of the syllabus for analysing each energy system?
4
