Verified step by step guidance

Understand the types of proteins listed in the options: fibrous, globular, conjugated, and membrane-bound. Each type has distinct structural and functional characteristics.

Fibrous proteins are elongated and insoluble, often playing structural roles (e.g., collagen, keratin). Globular proteins are compact, soluble, and typically involved in metabolic functions (e.g., enzymes, hemoglobin). Conjugated proteins are proteins combined with a non-protein component (e.g., glycoproteins, lipoproteins). Membrane-bound proteins are associated with cell membranes and can be integral or peripheral.

Analyze the context of the question and the visual representation of Arrow A. Determine whether the protein indicated by Arrow A fits the description of fibrous, globular, conjugated, or membrane-bound based on its structure and function.

If the protein indicated by Arrow A is elongated and primarily structural, it is likely a fibrous protein. If it is compact and involved in metabolic processes, it is likely globular. If it has a non-protein component, it is conjugated. If it is associated with the membrane, it is membrane-bound.

Select the correct answer based on the characteristics of the protein indicated by Arrow A and match it to the appropriate category from the options provided.
