Glucose is converted into glucose 6-phosphate in a series of reactions. This series is an example of what?

The conversion of glucose into glucose 6-phosphate is indeed an example of a metabolic pathway. A metabolic pathway is a series of biochemical reactions that occur within a cell, where each reaction is catalyzed by a specific enzyme and leads to a specific product. This transformation of glucose is a key step in various metabolic pathways, particularly in glycolysis and energy metabolism.

In this case, the process involves the phosphorylation of glucose, which is the addition of a phosphate group, typically from ATP, to glucose to form glucose 6-phosphate. This reaction is crucial as it helps to trap glucose within the cell and prepares it for further metabolism.

Understanding metabolic pathways is essential, as they illustrate how cells process nutrients and generate energy. The other options do not correctly describe this process: biosynthetic reactions involve building larger molecules from smaller ones, hydrolysis involves breaking bonds by adding water, and feedback inhibition refers to a regulatory mechanism where the end product of a pathway inhibits an earlier step. Each of these concepts plays a significant role in cellular processes, but they do not specifically pertain to the conversion of glucose to glucose 6-phosphate as a series of reactions.
