Question 2 0/2 pts The following graph represents 2 reactions, A and B, both catalyzed by the enzyme hexokinase. You have already learned about enzyme kinetics and what velocity of a reaction represents. Identify the true statement about this graph: 100 T e 50 [Glucose] (mM) .Reaction A happens at low ATP concentrations Reaction B happens at low ATP concentrations The kinetics of the reaction will not depend on ATP or glucose-6-phosphate Reaction B happens when concentration of Glucose-6phosphate are low Reaction A happens when concentrations of Glucose-6-phosphate are low

Explanation / Answer

The enzyme hexokinase regulated by excess glucose 6 phosphate present in the Cell.

ATP dependent hexokinase converts glucose to glucose -6 phosphate in eukaryotes.

The answer is reaction A happens at low ATP concentration.

At low ATP concentration the amount of glucose converted into glucose 6 phosphate is low. The reaction takes place at slower rate.

Reaction B

At high ATP concentrations like in Reaction B the amount of glucose converted into glucose 6 phosphate is more. The Reaction takes place at faster rate
