There is as much energy used to add a phosphate group by means of phosphorolysis, as the energy required adding a phosphate usin
xxTIMURxx [149]

The correct answer is (B) False.

There is not as much energy used to add a phosphate group by means of phosphorolysis, as the energy required adding a phosphate using ATP.

What is Phosphorolysis?

  • Glycogen phosphorolysis is a process that occurs at the start of glycogen breakdown. As a result, glucose can be produced from glycogen.
  • Glycogen phosphorolylsis catalyzes glycogen phosphorolytic cleavage, resulting in glycogen-1-phosphate.
  • However, when cleaving glucose from glycogen, a non-reducing terminal is eliminated.
  • Furthermore, phosphoglucomutase can convert glucose-1-phosphate generated from glycogen into G6P, allowing it to go directly to glycolysis.
  • It should be noted that going straight to glycolysis eliminates the need for ATP to convert glucose to G6P.
  • If the glucose created by glycolysis is consumed, three ATPs are produced.
  • Phosphorolysis requires less energy than ATP to add a phosphate group.
