Question

Answer

Transformation of membrane is the function of golgi complex.

Answer

Golgi apparatus function in membrane transformations and product compartmentalization:

Answer

Morphological and biochemical studies indicate that plasma membranes (PM) are derived from nuclear membranes (NM) or endoplasmic reticulum (ER) via the Golgi apparatus (GA) by a process of membrane flow and differentiation.According to this concept, membranes are transferred and transformed along a chain of cell components in a subcellular developmental pathway.

Answer

The correct answer is option 'B', Golgi complex. The Golgi complex plays a crucial role in the transformation of the membrane within a cell. Let's explore this in detail:

Golgi Complex:
The Golgi complex, also called the Golgi apparatus or Golgi body, is a membrane-bound organelle found in eukaryotic cells. It is involved in various functions, including the modification, sorting, and packaging of proteins and lipids for transport to their final destinations.

Function of Golgi Complex in Membrane Transformation:

1. Protein Modification:
- The Golgi complex receives proteins from the endoplasmic reticulum (ER) in vesicles.
- Within the Golgi, the proteins undergo post-translational modifications, such as glycosylation (addition of sugar molecules), phosphorylation (addition of phosphate groups), and sulfation (addition of sulfate groups).
- These modifications are essential for the proper folding, stability, and function of the proteins.

2. Sorting and Packaging:
- After modification, the Golgi complex sorts the proteins into different vesicles based on their destination.
- It acts as a distribution center, directing proteins to various cellular compartments, such as lysosomes, plasma membrane, or secretion.
- Different regions of the Golgi complex, known as cis, medial, and trans cisternae, are involved in this sorting process.

3. Lipid Metabolism:
- The Golgi complex is also involved in lipid metabolism.
- It synthesizes lipids, such as phospholipids and cholesterol, and modifies them with various enzymes.
- These modified lipids are then incorporated into cellular membranes, contributing to their transformation and fluidity.

4. Formation of Lysosomes:
- The Golgi complex plays a crucial role in the formation of lysosomes.
- It receives enzymes from the ER and modifies them within its compartments.
- These modified enzymes are then packaged into vesicles called lysosomes, which are responsible for intracellular digestion.

In conclusion, the Golgi complex is responsible for the transformation of the membrane by modifying proteins, sorting and packaging them into vesicles, participating in lipid metabolism, and facilitating the formation of lysosomes. These processes are essential for maintaining the integrity and functionality of the cell's membrane system.
