aerobic respiration Flashcards
1
Q
properties of ATP
A
- quickly broken down & resynthesised
- energy released immediately
-soluble in water where most chemical reactions occur
2
Q
functions of ATP
A
- active transport
- cell division
- muscle contraction
- first stage of glycolysis
3
Q
in glycolysis glucose is converted to?
A
pyruvate
4
Q
hydrolysis of ATP does what to glucose?
A
phosphorylates it - makes it more active
5
Q
pyruvate contains how many carbons
A
3
6
Q
net result of glycolysis
A
2 ATP 2 NADH
7
Q
glycolysis takes place..
A
cytoplasm
8
Q
how many ATP needed to start glycolysis
A
2
9
Q
before entering Krebs cycle pyruvate is converted to
A
acetylcoA
10
Q
what 2 reactions take place in link reaction
A
oxidation
decarboxylation
11
Q
link reaction/KC takes place..
A
matrix of mitochondria
12
Q
what is removed in KC
A
co-enzyme A
CO2
13
Q
what’s reduced in KC and by how many (single cycle)
A
NAD - NADH
2NAD - 2NADH
FAD - FADH
14
Q
how many times does LR/KC have to occur - why
A
twice
due to 2 pyruvate mol produced by glycolysis
15
Q
what is the final e acceptor
A
O2
