What is substrate level phosphorylation?
A) phosphorylation of AMP by ATP
B) ATP synthesis when the phosphate donor is a substrate with high phosphoryl transfer potential
C) phosphorylation of glycolytic intermediates
D) phosphorylation of ATP coupled to an ion gradient
E) ATP and AMP synthesis from two molecules of ADP

Question

Quizplus · Accepted Answer

Substrate-level phosphorylation is a way of generating ATP in which a phosphate group is transferred from a substrate molecule—which has a high phosphoryl transfer potential—to ADP, forming ATP. This process occurs in glycolysis and the Krebs cycle and does not involve the electron transport chain or an ion gradient.
