Cell Respiration & Exercise Flashcards
1
Q
is cellular respiration exothermic or endothermic?
A
exothermic
2
Q
Describe cellular respiration
A
an exothermic reaction which is continuously occurring in living cells
3
Q
what are the 2 types of respiration?
A
aerobic and anaerobic
4
Q
Equation for aerobic respiration in animals
A
glucose + oxygen -> carbon dioxide + water
C6H12O6 + 6O2 -> 6CO2 + 6H2O
5
Q
Equation for anaerobic respiration in animals
A
glucose -> lactic acid
C6H12O6 -> 2C3H6O3
6
Q
Equation for anaerobic respiration in plants and yeast cells
A
glucose -> ethanol + carbon dioxide
7
Q
what is oxygen debt?
A
the amount of extra O2 the body needs after exercise to react with accumulated lactic acid oxidise back to glucose
