The step involving ATP, hexokinase and the phosphorylation of glucose to glucose-6-phosphate is

Question

Quizplus · Accepted Answer

This step involves the enzyme hexokinase transferring a phosphate group from ATP to glucose, resulting in the production of glucose-6-phosphate. This is an example of substrate-level phosphorylation, where ATP is generated directly from the transfer of a phosphate group to an acceptor molecule. It occurs in the cytoplasm during glycolysis, before the Krebs cycle and electron transport chain. It is not an example of oxidative phosphorylation, which involves the use of a proton gradient to produce ATP, nor photophosphorylation, which occurs during photosynthesis.
