aerobic & anaerobic respiration Flashcards
1
Q
aerobic
A
with oxygen
2
Q
anaerobic
A
without oxygen
3
Q
word equation for aerobic respiration
A
glucose + oxygen → carbon dioxide + water
4
Q
word equation for anaerobic respiration - for mammals and yeast
A
glucose → - lactic acid (mammals)
- ethanol + carbon dioxide (yeast
5
Q
which place in the cell is where respiration takes place
A
mitochondria
6
Q
why do muscle cells need a lot of mitochondria
A
to have energy to move
7
Q
what is needed for aerobic respiration to take place
A
oxygen
8
Q
when does anaerobic respiration take place
A
when the oxygen level is too low
9
Q
oxygen debt
A
after anaerobic respiration, we need oxygen to break down the lactic acid
10
Q
fermentation
A
yeast respire anaerobically.
use ethanol = beer / wine
carbon dioxide = bread rise
11
Q
changes in body when exercising
A
- breathing rate ↑
- heart rate ↑
- sweat ↑
