List enzymes in order in priming phase of glycolysis
A
Hexokinase
Phosphohexase isomerase
Phosphofructokinase
Aldose
2
Q
Hexokinase
A
Phosphorylates C6
3
Q
Phosphohexase isomerase
A
Moves carbonyl (double bond) from C1 to C2
4
Q
Phosphofructokinase
A
Phosphorylates C1
5
Q
Aldose
A
Cleaves after C3–>2 PGALs
6
Q
List enzymes in payoff phase of glycolysis
A
Dehydrogenase Kinase Mutase Enolase Pyruvate kinase
7
Q
Dehydrogenase
A
C3 is phosphorylated
8
Q
Kinase
A
Substrate level phosphorylation–> ATP
9
Q
Mutase
A
Phosphoryl moves from C3 to C2
10
Q
Enolase
A
Dehydration (double bond between C1=C2)
11
Q
Pyruvate kinase
A
Substrate level phosphorylation—>ATP
12
Q
1 Glucose yields…
A
2 pyruvate
2 NADH
2 ADP
4 ATP (2 net)
13
Q
How many CO2 produced in glycolysis
A
None
14
Q
Why is G6P isomerase drop F6P
A
Allows phosphorylation at C1 amd that both sides have a P
15
Q
F16BP to two pyruvate yields
A
2 NADH
4 ATP
