Which cell organelles secretes zymogen granules

Options

A. Lysosomes
B. Golgibody
C. Smooth E.R.
D. Sphaerosomes

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks which cell organelle is responsible for the secretion of zymogen granules. Zymogen granules are precursors to enzymes that are secreted by certain cells.

2. **Identifying the Organelles**: The options provided in the question include lysosomes, Golgi bodies, smooth endoplasmic reticulum, and spharyosomes. We need to analyze each of these organelles to determine which one is responsible for secreting zymogen granules.

3. **Analyzing the Smooth Endoplasmic Reticulum (SER)**: The smooth endoplasmic reticulum (SER) is known for its role in various metabolic processes. One of its key functions is the synthesis of lipids, phospholipids, and steroids.

4. **Linking SER to Zymogen Granules**: The SER is also involved in the secretion of zymogen granules. Zymogens are inactive enzyme precursors, and their secretion is essential for various biochemical processes, particularly those involving hydrolysis.

5. **Conclusion**: Based on the functions of the organelles discussed, the smooth endoplasmic reticulum (SER) is the correct answer as it is responsible for secreting zymogen granules.

### Final Answer:
The cell organelle that secretes zymogen granules is the **smooth endoplasmic reticulum (SER)**.
