Verified step by step guidance

Step 1: Begin by understanding the role of proteins in metabolic reactions. Proteins are macromolecules that perform various functions in the body, including catalyzing biochemical reactions.

Step 2: Recall the definition of enzymes. Enzymes are specialized proteins that act as biological catalysts, meaning they speed up the rate of metabolic reactions without being consumed in the process.

Step 3: Compare the functions of the other options provided: Receptors are proteins that bind signaling molecules to initiate cellular responses, Hormones are signaling molecules that regulate physiological processes, and Antibodies are immune system proteins that recognize and neutralize foreign substances.

Step 4: Identify that enzymes are the correct answer because they directly control the rate of metabolic reactions by lowering the activation energy required for these reactions to occur.

Step 5: Conclude that enzymes are distinct from the other options because their primary function is catalysis, which is essential for maintaining the efficiency of metabolic pathways.
