What enzyme is used to catalyze the first primary reaction of glycolysis?
Open in App
Solution
The correct option is A Hexokinase
Glycolysis is an oxygen independent metabolic pathway that converts glucose, into pyruvate.
This process of conversion can be divided into two stages, a preparatory stage and a pay-off stage.
The intial five steps of glycolysis are known as the preparatory stage. During these steps there is consumption of ATP and is also known as the investment stage.
The remianing steps of glycolysis are known as the pay-off phase of glycolysis. This phase is characterized by gain of the energy-rich molecules ATP and NADH.
The first step in the preparatory stage of glycolysis is phosphorylation. During this step, glucose is phosphorylated to glucose-6-phosphate by the enzyme hexokinases with the consumption of an ATP molecule.
