additional biology- respiration Flashcards
1
Q
what is respiration
A
the process of releasing energy from the breakdown of glucose
2
Q
what does aerobic respiration need
A
lots of oxygen
3
Q
where does aerobic respiration take place
A
in the mitochondria
4
Q
what is the word equation for aerobic respiration
A
glucose+oxygen-carbon dioxide+water+energy
5
Q
what is the energy released by aerobic respiration used for
A
- to build up large molecules from smaller ones
- in animals to allow muscles to contract
- in birds to keep their body temperature steady
- in plants to build sugar etc into amino acids
6
Q
when is anerobic respiration used
A
when there is no oxygen
7
Q
what is anerobic respiration
A
the incomplete breakdown of glucose which produces lactic acids
8
Q
what is the equation for anerobic respiration
A
glucose-energy+lactic acid
9
Q
what can anerobic respiration cause
A
- muscle fatigue
- the build up of lactic acid in the muscle
10
Q
what does anerobic respiration lead to
A
-oxygen debt
