Factors Affecting O2 Consumption Flashcards
1
Q
How specifically do most animals follow allometric scaling? (3)
A
- inter-species comparisons
- development within same species
- cellular level
2
Q
What is whole animal MR?
A
- MR proportional to body mass
(increases with size)
3
Q
What is mass specific MR?
A
- inversely proportional to body mass (decreases with size)
4
Q
Whats the difference in MO2 during life stage?
A
- eggs have low MO2 (increases post hatch)
- MO2 juveniles > MO2 adult
5
Q
Why is MO2 juveniles > MO2 adult?
A
they’re growing
6
Q
What is standard MR?
A
- baseline MR
7
Q
What is specific dynamic action (SDA)?
A
- heat increment of feeding (digestion + assimilation)
8
Q
What is standard rate?
A
- SMR at rest
9
Q
What is active rate?
A
- max MR (MMR)
10
Q
How do you calculate scope for activity/aerobic scope?
A
MMR - SMR
11
Q
Higher activity = ____ MR
A
higher
12
Q
MO2 is ____ to red muscle activity. What does this mean?
A
- proportional
- if red muscle activity increases, so does MO2
13
Q
SMR ____ with temp
A
- increases
14
Q
What is Q10?
A
- change in MR for every 10 degree C increase in temp
15
Q
What is the main factor to performance in temp increase differences across species?
A
- thermotolerance/temp tolerance
