Exam 2 Energy Production Flashcards
(10 cards)
1
Q
What is metabolism
A
Sum of all chemical processes needed to maintain body
2
Q
What is metabolic rate
A
Rate at which your body uses energy
3
Q
What is glucose
A
- simple sugar that use created by broken down carbs
- used to fuel ATP
4
Q
What is glycogen
A
- stored form of glucose
- complex carb
Stored in liver and skeletal muscles - stored as fat if its not needed
5
Q
What is ATP
A
The energy source for all cellular processes
- produced by mitochondria
6
Q
Explain the immediate system and limiting factors
A
- gets tired quick (0-10s)
- high intensity activities
- ATP rate = immediate
- fuel = ATP and creatine
- no oxygen used
Limiting factors:
1. Limited supply of ATP and creatine
7
Q
Explain the non-oxidative system and limiting factors
A
- gets tired kinda fast (10s -2min)
- moderate- high intensity activities
- rate of ATP= quick
- fuel = glucose + glycogen
- no oxygen
Limiting factors
1. Limited supply of glucose and glycogen
2. Lactic acid
8
Q
Explain the Oxidative system and limiting factors
A
- doesnt get tired fast
- low intensity activities
- slow rate of atp
- fuel = glycogen, glucose, fats protein
- oxygen
Limiting factors
1. Glycogen depletion
2. VO2 max can only be so high
9
Q
Vo2max
A
Highest rate of oxygen consumption a person is capable of during max PA
10
Q
How does being less fit effect energy production
A
- Can’t deliver o2 and fuel to muscles very good
- Can’t burn as many cals during or after exercise
- Can’t cope with lactate
