How many ATP molecules are utilized in the glycolysis of a glucose molecule?
Options
- A
- B
- C
- D
Correct answer
D.
Step-by-step solution
Glycolysis involves an energy investment phase where ATP is consumed.
One ATP molecule is utilized during the conversion of glucose to glucose-6-phosphate, catalyzed by the enzyme hexokinase.
Another ATP molecule is utilized during the conversion of fructose-6-phosphate to fructose-1,6-bisphosphate, catalyzed by the enzyme phosphofructokinase.
Therefore, a total of ATP molecules are utilized in the glycolysis of a single glucose molecule.
