New cards
What enzyme performs glycolysis step 1?
Hexokinase.
2
New cards
What is the substrate in glycolysis step 1?
Glucose.
3
New cards
What is the product of glycolysis step 1?
Glucose-6-phosphate.
4
New cards
What happens in glycolysis step 1?
Glucose → glucose-6-phosphate; ATP is used.
5
New cards
What enzyme performs glycolysis step 2?
Phosphoglucose isomerase.
6
New cards
What is the substrate in glycolysis step 2?
Glucose-6-phosphate.
7
New cards
What is the product of glycolysis step 2?
Fructose-6-phosphate.
8
New cards
What happens in glycolysis step 2?
Glucose-6-phosphate → fructose-6-phosphate.
9
New cards
What enzyme performs glycolysis step 3?
Phosphofructokinase.
10
New cards
What is the substrate in glycolysis step 3?
Fructose-6-phosphate.
11
New cards
What is the product of glycolysis step 3?
Fructose-1,6-bisphosphate.
12
New cards
What happens in glycolysis step 3?
Fructose-6-phosphate → fructose-1,6-bisphosphate; ATP is used.
13
New cards
What enzyme performs glycolysis step 4?
Aldolase.
14
New cards
What is the substrate in glycolysis step 4?
Fructose-1,6-bisphosphate.
15
New cards
What are the products of glycolysis step 4?
DHAP and GAP.
16
New cards
What happens in glycolysis step 4?
Fructose-1,6-bisphosphate is split into two 3-carbon molecules.
17
New cards
What enzyme performs glycolysis step 5?
Triose phosphate isomerase.
18
New cards
What is converted during glycolysis step 5?
DHAP → GAP.
19
New cards
What happens in glycolysis step 5?
DHAP is rearranged into GAP.
