B12 respiration Flashcards
1
Q
uses of energy in living organisms
A
- muscle contraction
- protein synthesis
- cell division
- growth
- passage of nerve impulses
- maintenance of constant body temperature
2
Q
describe aerobic respiration
A
- the chemical reactions in cells
- that use oxygen to break down nutrient molecules
- to release energy
3
Q
word equation for aerobic respiration
A
4
Q
balanced symbol equation for aerobic respiration
A
5
Q
describe anaerobic respiration
A
- the chemical reactions in cells
- that break down nutrient molecules
- to release energy
- without using oxygen
6
Q
energy release in aerobic vs anaerobic respiration
A
anaerobic releases much less energy per glucose molecule
7
Q
word equation for anaerobic respiration
A
8
Q
when does anaerobic respiration occur
A
during vigorous exercise
9
Q
what happens during vigorous exercise
A
- lactic acid builds up in muscles and blood
- causes oxygen debt
10
Q
how is oxygen debt removed
A
after exercise
- continuation of fast heart rate to transport lactic acid in blood from muscles to liver
- continuation of deeper and faster breathing to supply oxygen for aerobic respiration of lactic acid
- aerobic respiration of lactic acid in liver
