5.1 Energy Transfer In The Body Flashcards
1
Q
Equation for aerobic and anaerobic respiration
A
AEROBIC
glucose + o2 -> Co2 + water + energy
ANAEROBIC
Glucose -> lactic acid + energy
2
Q
Define ATP
A
Organic chemical that provides energy in living cells
3
Q
Define phosphocreatine
A
Energy rich phosphate compound found in the sarcaplasm of the muscles
4
Q
Define a coupled reaction
A
When energy required by one process is supplied by another process
5
Q
Fuel, site, enzyme, yield, by-products of ATP/PC systems
A
Fuel: phosphocreatine
Site: sarcoplasm
Enzyme: creatine kinase
Yield: 1:1
By-products: nothing
6
Q
Advantages of ATP/PC system
A
- high intensity
- no harmful by-products
- no delay in o2 delivery (produced in the sarcoplasm in the muscles)
7
Q
Disadvantages of the ATP/PC system
A
- short duration 3 seconds / 10 seconds for high intensity short duration events
- inefficient low energy yield
