Seminal plasma in humans is rich in

Options

A. glucose and certain enzymes but has no calcium
B. fructose and certain enzymes but poor in calcium
C. fuctose, calcium and certain enzymes
D. fructose and calcium but has no enzymes

Explanation

To answer the question "Seminal plasma in humans is rich in," we will analyze the components of seminal plasma and identify the correct option based on its composition.

### Step-by-Step Solution:

1. **Understanding Seminal Plasma**:
- Seminal plasma is the fluid part of semen in which sperm cells are suspended. It is produced by various glands in the male reproductive system.

2. **Components of Seminal Plasma**:
- Seminal plasma contains secretions from several glands, including:
- Seminal vesicles
- Prostate gland
- Bulbourethral glands (Cowper's glands)
- Vasa deferentia

3. **Nutritional Components**:
- The primary components of seminal plasma include:
- **Fructose**: A sugar that provides energy to sperm.
- **Calcium**: Important for sperm motility and function.
- **Ascorbic Acid (Vitamin C)**: An antioxidant that protects sperm from oxidative stress.
- **Enzymes**: Various enzymes that may aid in the liquefaction of semen and other functions.

4. **Evaluating the Options**:
- Now, let’s evaluate the options provided in the question:
- **Option A**: Glucose and certain enzymes - Incorrect, as the sugar present is fructose, not glucose.
- **Option B**: Fructose and certain enzymes but poor in calcium - Incorrect, as seminal plasma is rich in calcium.
- **Option C**: Fructose, calcium, and certain enzymes - Correct, as all these components are indeed present in seminal plasma.
- **Option D**: Fructose and calcium but no enzyme - Incorrect, as enzymes are also present.

5. **Conclusion**:
- Based on the analysis, the correct answer is **Option C: Fructose, calcium, and certain enzymes**.
