Anaerobic Respiration Flashcards
1
Q
blood cannot . . .
A
supply enough O2 to respiring cells fast enough
2
Q
why is less energy transferred?
A
glucose molecules are not broken down completely
3
Q
animal equation
A
glucose -> lactic acid + (energy)
4
Q
muscle fatigue cause
A
vigorous use of muscle fibres
5
Q
muscle fatigue consequence
A
less efficient contractions, build up of lactic acid, O2 debt
6
Q
O2 debt
A
extra O2 needed to break down lactic acid, via aerobic
7
Q
higher the debt
A
higher the rate and depth of breathing/ heart rate
8
Q
lactic acid break down equation
A
lactic acid + O2 -> CO2 + H2O
9
Q
more fit means . . .
A
lower heart/breathing rate, bigger/better heart/lungs, more efficient blood supply, less time taken to return to resting rate after exercise
10
Q
plants and yeast equation
A
glucose -> ethanol + CO2
