Which type of protein provides structural support to cells and tissues?

• A. Transport proteins
• B. Structural proteins
• C. Enzymatic proteins
• D. Hormonal proteins

Answer: (B)

Verified step by step guidance

1. Understand the role of different types of proteins in biological systems. Proteins can have various functions such as structural support, transport, enzymatic activity, and hormonal signaling.
2. Identify the function of structural proteins. These proteins provide support and shape to cells and tissues, helping maintain their integrity and form.
3. Consider examples of structural proteins. Common examples include collagen, which is found in connective tissues, and keratin, which is found in hair and nails.
4. Differentiate structural proteins from other types of proteins. Transport proteins, for example, help move substances across cell membranes, while enzymatic proteins catalyze biochemical reactions, and hormonal proteins are involved in signaling processes.
5. Conclude that structural proteins are specifically responsible for providing structural support to cells and tissues, distinguishing them from other protein types with different functions.
