Answer: 2. organelle
A different organelle controls each step of glycolysis.
Explanation:
The process of glycolysis breaks down each glucose molecule into two pyruvate molecules. The glucose molecule has 6 carbon atoms and the two pyruvates have 3 carbon atoms each.
Glycolysis contains 10 steps and each one of the steps is controlled by different enzymes.
The enzymes controlling each of the 10 steps are given below
Step1- hexokinase phosphorylates
Step 2-ophosphoglucoismerase
Step 3-phosphofructokinase
Step 4-aldolase
Step 5-triose phosphate isomerase
Step 6-triose phosphate dehydrogenase
Step 7-phosphoglycerokinase
Step 8-phosphoglyceromutase
Step 9-enolase
Step 10-pyruvate kinase
