Question

There are three main types of cellular work: chemical, transport, and movement. Most of this work is powered by the transfer of a phosphate group from one molecule to another in a process known as______________

Answer 1

phosphorylation

Step-by-step explanation:

Phosphorylation is the process wherein a phosphate group from a donor compound is removed. The removed phosphate group is then added to the recipient compound. Here, the recipient molecule is said to have undergone phosphorylation. Kinases are the enzymes that catalyze these reactions.

During most of the chemical pathways, phosphorylation of substrates activates them for the subsequent reactions. For example, glucose is being activated when it is phosphorylated into glucose 6-phosphate during the first reaction of glycolysis. The ATP molecule serves as the donor of the phosphate group in this reaction.
