Receptors of hormones are generally

Options

A. Carbohydrates
B. Vitamins
C. Lipids
D. Protiens

Answer

To solve the question "Receptors of hormones are generally," we can follow these steps:

### Step 1: Understand what hormones are
Hormones are chemical messengers produced by endocrine glands in the body. They are secreted into the bloodstream and travel to various organs and tissues to regulate physiological processes.

**Hint**: Remember that hormones are produced by glands and have specific functions in the body.

### Step 2: Identify the role of hormone receptors
Receptors are specific molecules that hormones bind to in order to exert their effects. These receptors are crucial for the hormones to communicate with target cells and initiate a response.

**Hint**: Think about how hormones need to interact with specific sites to have an effect.

### Step 3: Analyze the options given
The options provided are carbohydrates, vitamins, lipids, and proteins. We need to determine which of these is most commonly associated with hormone receptors.

**Hint**: Consider the nature of each option and their typical roles in biological systems.

### Step 4: Determine the correct answer
Among the options, proteins are the most common type of molecules that serve as receptors for hormones. Hormone receptors are typically proteins that undergo conformational changes upon binding with a hormone, which then triggers a biological response.

**Hint**: Recall that proteins have diverse functions in the body, including acting as receptors.

### Conclusion
The receptors of hormones are generally **proteins**.

**Final Answer**: Proteins (Option D)
