Proteins which help other proteins to fold properly are called

Options

A. Chaperons
B. Actins
C. Porins
D. Synthases.

Answer

To solve the question "Proteins which help other proteins to fold properly are called," we can follow these steps:

### Step 1: Understand the Question
The question is asking for a specific type of protein that assists other proteins in achieving their proper three-dimensional structure, which is crucial for their functionality.

**Hint:** Think about the role of proteins in the cell and how they achieve their functional shapes.

### Step 2: Analyze the Options
We have four options to consider:
1. Chaperones
2. Actins
3. Porins
4. Synthesis

**Hint:** Review what each of these terms refers to in the context of biology.

### Step 3: Identify the Function of Each Option
- **Chaperones:** These are proteins that assist in the proper folding of other proteins, ensuring they attain their stable structure.
- **Actins:** These are structural proteins that form part of the cytoskeleton but do not assist in protein folding.
- **Porins:** These are proteins that form pores in membranes, not related to protein folding.
- **Synthesis:** This term refers to the process of creating proteins, not a type of protein itself.

**Hint:** Focus on the definitions and functions of the proteins listed in the options.

### Step 4: Select the Correct Answer
From the analysis, we can conclude that the correct answer is **Chaperones** because they are specifically known for their role in assisting other proteins to fold correctly.

**Hint:** Remember that the term "chaperone" is often used in molecular biology to describe this specific function.

### Step 5: Confirm the Answer
The role of chaperones is well-documented in biological literature, and they are essential for protein stability and function. They often utilize ATP to facilitate the folding process.

**Hint:** Consider the importance of protein folding in cellular processes and how chaperones contribute to this.

### Final Answer
The proteins which help other proteins to fold properly are called **Chaperones**.
