To Be Metabolized, Glucose Must Be Converted to Glucose 6-Phosphate

question 175

Multiple Choice

To be metabolized, glucose must be converted to glucose 6-phosphate.However, the phosphorylation of glucose to form glucose 6-phosphate is endergonic with a positive G.How do cells circumvent this problem?

• A) The reaction is catalyzed by an enzyme, which allows the reaction to proceed by changing its  G.
• B) The reaction is catalyzed by an enzyme, which allows the reaction to proceed by lowering its activation energy.
• C) An enzyme raises the activation energy barrier to favor glucose 6-phosphate formation.
• D) An enzyme changes the equilibrium constant for the reaction to favor glucose 6-phosphate formation.
• E) The reaction is coupled to the hydrolysis of ATP, making the entire process exergonic.
