glycolisis Flashcards
1
Q
step 1:
A
- phosphorylation of glucose by ATP (converts to ADP)
- enzyme: kinase
2
Q
step 2:
A
- G6P to F6P
- enzyme: isomerase
3
Q
step 3:
A
- 2nd ATP phosphorylation
- enzyme: kinase
4
Q
step 4 and 5:
A
- 6C molecule splits into 2 3Cs: 1 G3P, another in another reaction
- enzymes: aldolase (4) and isomerase (4,5)
5
Q
step 6:
A
- oxidation, then phosphorylation produces 2 NADHs and 2 BPGs (each with 1 high energy phosphate bond)
- G3P to 1, 3 BPG (x2)
- enzyme: Glyceraldehyde 3-phosph Dehydrogenase
6
Q
step 7:
A
- removal of high energy phosphate by 2 ADPs produces 2 ATPs and leaves 3 3PGs
- 1,3 BPG (x2) to 3PG
- kinase
7
Q
step 8, 9;
A
- removal of high energy phosphate by 2 ADP molecules produces 2 ATP molecules and 2 pyruvates
- enzymes: mutase (8) and enolase (9)
8
Q
step 10:
A
- removal of water yields 2 PEPs, each with high energy phosphate bond
- PEP to pyruvate
- pyruvate kinase
9
Q
first five reactions
A
convert glucose to G3P
10
Q
last five reactions
A
convert G3P into pyruvate
11
Q
when is ATP used and made
A
1, 3, 7, 10
12
Q
when is NADH reduced
A
6 (NAD + G3P => NADH)
13
Q
when is water released
A
9 (each 2PG releases H2O)
14
Q
what does kinase do
A
adds phosphate group
15
Q
what does isomerase do
A
converts one isomer to another
