Hydrolysis of ATP releases energy,which ultimately results in the production of ADP and inorganic phosphate.What is commonly the immediate fate of the phosphate released by ATP hydrolysis in the cell?
A)It is secreted as waste.
B)It diffuses through an ion channel into the Golgi apparatus,where it modifies secreted proteins.
C)It is attached to ADP to regenerate ATP.
D)It is attached to a substrate to form a phosphorylated intermediate.

Question

Quizplus · Accepted Answer

The phosphate released by ATP hydrolysis is commonly immediately attached to a substrate to form a phosphorylated intermediate, such as in the process of activating glucose in glycolysis. This phosphorylation is an important regulatory step in many metabolic pathways.Option A is incorrect as the phosphate is not secreted as waste but is immediately used in metabolic reactions. Option B is incorrect as the Golgi apparatus is not involved in ATP hydrolysis or the immediate fate of the phosphate released. Option C is incorrect as the process of attaching the released phosphate to ADP to regenerate ATP requires energy input and is not an immediate fate of the released phosphate.
