Which of the following types of enzymes catalyse the covalent addition of inorganic phosphate to a molecule?Group of answer choicesDehydrogenasesIsomerasesPhosphorylasesHydratases
Solution
The type of enzyme that catalyses the covalent addition of inorganic phosphate to a molecule is Phosphorylases.
Step by Step Explanation:
-
Enzymes are biological catalysts that speed up chemical reactions in cells. They do this by lowering the activation energy of the reaction.
-
Each type of enzyme is specialized to catalyze a specific type of reaction.
-
Phosphorylases are a type of enzyme that adds an inorganic phosphate group (PO4) to a molecule in a process called phosphorylation.
-
During this process, the phosphorylase enzyme catalyzes the transfer of a phosphate group from inorganic phosphate (Pi) to an acceptor molecule.
-
Therefore, the correct answer is Phosphorylases.
Dehydrogenases are involved in redox reactions, isomerases catalyze the rearrangement of atoms within a molecule, and hydratases are involved in the addition or removal of water, but none of these are involved in the addition of inorganic phosphate to a molecule.
