Verified step by step guidance

Understand the role of ATP in biochemical reactions: ATP (adenosine triphosphate) is often used as an energy source in cells, particularly in reactions that require energy input to proceed.

Identify the function of each enzyme class: Lyases break bonds by means other than hydrolysis and oxidation, Transferases transfer functional groups from one molecule to another, Oxidoreductases catalyze oxidation-reduction reactions, and Ligases catalyze the joining of two molecules with the concomitant hydrolysis of ATP.

Focus on the function of Ligases: Ligases are enzymes that facilitate the joining of two molecules, often requiring the input of energy from ATP to form a new chemical bond.

Relate the enzyme function to the reaction: Since the problem involves combining two molecules using ATP, the enzyme class that fits this description is Ligase.

Conclude that Ligases are the class of enzymes required for reactions that combine two molecules with the use of ATP, as they catalyze the formation of new bonds with energy input from ATP.
