Answer: (B)

Verified step by step guidance

1. Understand the role of membrane proteins: Membrane proteins are integral or peripheral proteins that are part of, or interact with, cell membranes. They perform a variety of functions essential for cellular processes.
2. Identify the types of membrane proteins: The main types include transport proteins, enzymatic proteins, structural proteins, and receptor proteins, each with distinct functions.
3. Focus on enzymatic proteins: Enzymatic proteins are a type of membrane protein that catalyze chemical reactions. They lower the activation energy required for reactions, facilitating biochemical processes.
4. Differentiate enzymatic proteins from others: Unlike transport proteins (which move substances across the membrane), structural proteins (which provide support and shape), and receptor proteins (which receive signals), enzymatic proteins specifically catalyze reactions.
5. Conclude with the correct identification: Based on their function of catalyzing chemical reactions, enzymatic proteins are the type of membrane protein that fits the description in the problem.
