***Effects of temp on swimming Flashcards
1
Q
What kind of animal are sockeye salmon
A
- ectothermic pokilotherms
2
Q
What do you look at for effects of temp on swimming
A
- environmental temp vs body temp
3
Q
How does temp change have a direct effect on swimming?
A
- body temp changes with environment
4
Q
reaction rates ___ with temp
A
- increase
5
Q
as temp increases, reaction rates ___
A
- increase
6
Q
Reaction rates are _____ and happen in ______.
A
- enzymatic
- in cells
7
Q
reaction rate increases make _____ more efficient
A
muscle contraction
8
Q
Viscosity ____ as temp increases
A
- decreases
9
Q
increase of temp and decrease of viscosity = ?
A
- decreased drag (more efficient)
10
Q
Density ____ with temp increase
A
- small decrease
11
Q
why after a certain temp does speed/performance decrease?
A
- O2 demand increases with temp and O2 solubility decreases (less oxygen available)
12
Q
at a specific temp, demand overcomes ___ which ____ performance.
A
- supply
- decreases
13
Q
What is OCLTT?
A
- Oxygen + capacity limited thermal model
14
Q
What is oxygen and capacity limited thermal model?
A
- supply: O2 uptake
–> circulatory system for O2 delivery
–> at high temp, limitation (performance and health decrease)
15
Q
What happens at lethal temp
A
- failure of system
