Verified step by step guidance

Understand the role of enzymes in biochemical reactions: Enzymes are biological catalysts that speed up chemical reactions without being consumed in the process. Each enzyme has a specific function based on its structure and active site.

Learn the function of a kinase: A kinase is an enzyme that transfers phosphate groups from ATP (adenosine triphosphate) to other molecules, typically proteins, in a process called phosphorylation. This is a key regulatory mechanism in cellular signaling and metabolism.

Differentiate between the given enzyme types: Isomerase rearranges atoms within a molecule, Ligase joins two molecules together, and Phosphatase removes phosphate groups from molecules. Kinase specifically adds phosphate groups, which is distinct from the other enzyme types.

Relate the function of ATP: ATP is the primary energy currency of the cell, and its phosphate groups are often used in phosphorylation reactions. Kinases utilize ATP as a phosphate donor in these reactions.

Conclude the correct answer: Based on the definition and function of a kinase, the general name for an enzyme that transfers phosphate groups from ATP to other molecules is 'Kinase'.
