Bacterial flagella is made up of

Options

A. Amines
B. Proteins
C. Lipids
D. Carbohydrates.

Answer

To answer the question "Bacterial flagella is made up of," we can follow these steps:

### Step 1: Understand the Structure of Bacterial Flagella
Bacterial flagella are long, thread-like structures that extend from the surface of bacterial cells. They play a crucial role in the movement of bacteria.

**Hint:** Consider the function of flagella in bacteria and what materials are typically involved in their construction.

### Step 2: Identify the Composition of Flagella
The primary component of bacterial flagella is a protein known as flagellin. This protein polymerizes to form the filamentous structure of the flagellum.

**Hint:** Think about the types of biological macromolecules and which ones are commonly associated with structural functions in cells.

### Step 3: Review the Options Provided
The options given are:
1. Amines
2. Proteins
3. Lipids
4. Carbohydrates

From our understanding, flagella are primarily made of proteins, specifically flagellin.

**Hint:** Eliminate options that do not fit the known composition of flagella.

### Step 4: Conclude the Answer
Based on the information gathered, the correct answer to the question is that bacterial flagella are made up of **proteins**.

**Final Answer:** Bacterial flagella are made up of **proteins**.
