Verified step by step guidance

Understand the concept: The removal of a phosphate group from a molecule is a biochemical process. This process is commonly referred to as 'dephosphorylation.' It is the opposite of 'phosphorylation,' which involves the addition of a phosphate group.

Clarify the options: Phosphorylation refers to the addition of a phosphate group, so it cannot be the correct answer. Hydrolysis involves breaking chemical bonds using water, but it does not specifically refer to the removal of a phosphate group. Methylation involves the addition of a methyl group, which is unrelated to phosphate groups.

Focus on the correct term: Dephosphorylation is the specific term used to describe the removal of a phosphate group from a molecule. This process is often catalyzed by enzymes called phosphatases.

Relate to biochemical significance: Dephosphorylation plays a critical role in regulating cellular processes, such as signal transduction and enzyme activity, by altering the phosphorylation state of proteins and other molecules.

Conclude the reasoning: Based on the definitions and biochemical context, the correct answer to the question is 'Dephosphorylation,' as it directly describes the removal of a phosphate group from a molecule.
