Unit 3.3 - Respiration Flashcards
1
Q
why is respiration described as a catabolic process
A
complex molecules broken down into smaller, simpler molecules
2
Q
why do organisms need to respire
A
- produces ATP
- releases heat energy
3
Q
what is ATP needed for
A
- active transport
- metabolic reactions
- muscle contractions
4
Q
where does glycolysis occur
A
cytoplasm
5
Q
where does the link reaction occur
A
mitochondrial matrix
6
Q
where does the krebs cycle occur
A
mitochondrial matrix
7
Q
where does the ETC occur
A
inner mitochondrial membrane
8
Q
outline stages of glycolysis
A
- Glucose(6C) phosphorylated —> Hexose Bisphosphate (using 2x ATP)
- Hexose Bisphosphate –> 2x Triose Phosphate
- 2x Triose Phosphate oxidised –> pyruvate
9
Q
what is produced during glycolysis PER GLUCOSE
A
2x Reduced NAD
2x ATP
10
Q
how does pyruvate from glycolysis enter the mitochondria
A
via active transport
11
Q
A
