The proteins with a prosthetic group are called

Options

A. Pseudo
B. complex proteins
C. Conjugated proteins
D. Polypeptides

Explanation

To answer the question "The proteins with a prosthetic group are called," we can follow these steps:

### Step 1: Understand the Definition of Proteins
Proteins are large biomolecules made up of amino acids and play crucial roles in biological processes. They can be classified into different categories based on their structure and composition.

**Hint:** Remember that proteins can be simple or complex based on their components.

### Step 2: Define Prosthetic Groups
A prosthetic group is a non-polypeptide unit that is tightly and permanently attached to a protein. It is essential for the biological activity of the protein. Common examples include metal ions (like iron in hemoglobin) or organic molecules (like heme).

**Hint:** Think about the role of non-protein components in enhancing protein function.

### Step 3: Identify Types of Proteins
Proteins can be classified into two main categories:
1. **Simple Proteins:** These consist only of amino acids.
2. **Conjugated Proteins:** These contain one or more prosthetic groups in addition to amino acids.

**Hint:** Focus on the distinction between simple and conjugated proteins.

### Step 4: Conjugated Proteins
Conjugated proteins are those that contain a prosthetic group. The combination of the protein part and the prosthetic group allows these proteins to perform specific functions that simple proteins cannot.

**Hint:** Recall that conjugated proteins are essential for various biological functions due to their unique structures.

### Step 5: Conclusion
Based on the understanding that proteins with a prosthetic group are classified as conjugated proteins, we can conclude that the correct answer to the question is "Conjugated Proteins."

**Final Answer:** The proteins with a prosthetic group are called **Conjugated Proteins**.
