#Question id: 10275


In the initial phase of glycolysis, each hexose unit is phosphorylated twice and then split, producing two molecules of triose phosphate, in these reactions included irreversible reaction. How much irreversible reaction is performed in the glycolytic pathway through in this series of reactions?

#XL - Q Biochemistry
  1. Include two of the three essentially irreversible reactions of the glycolytic pathway, which are catalyzed by hexokinase and phosphofructokinase
  2. Include two of the four essentially irreversible reaction, catalyzed by phosphohexose isomerase and aldolase
  3. Include two of the three essentially irreversible reactions, catalyzed by phosphohexose isomerase and phosphofructokinase
  4. Include two of the three essentially irreversible reactions, catalyzed by Triose phosphate isomerase and aldolase
