What would happen to the life of a cell if there was no Golgi apparatus?
Share
The materials synthesized in the ER are stored, sorted, modified, packaged and dispatched to various targets inside and outside the cell through the Golgi apparatus packs products in vesicles, the secretary vesicles. In some cases complex sugars e.g. cellulose, may be made from simple sugars in Golgi apparatus. The Golgi apparatus is also involved in the formation of the cells which will not be possible if Golgi apparatus is not there.

There would not be any lysosome for intracellular digestion and cleansing, not complexing of molecules, no exocytosis and no formation of new plasma membrane.
Effects of Missing Golgi Apparatus on Cell Function:
1. Protein Modification and Sorting:
– The Golgi apparatus is like a cell’s “packaging center.” It modifies and sorts proteins made in the cell.
– Without it, proteins wouldn’t get their final touches or be directed to the right places inside or outside the cell.
2. Vesicle Formation and Transport:
– Golgi creates tiny transport sacs called vesicles that move proteins and other materials around the cell.
– No Golgi means disrupted transport, affecting how the cell receives what it needs or sends things where they’re needed.
3. Secretion Issues:
– It’s vital for exporting important stuff out of the cell. Without a functioning Golgi, the cell might struggle to secrete enzymes or hormones properly.
4. Lysosome Problems:
– Golgi helps make lysosomes, which are like the cell’s garbage disposals. Without it, the cell might have trouble breaking down waste materials or recycling old parts.
5. Cell Stress and Dysfunction:
– Without a Golgi, there could be confusion in the cell, leading to stress and malfunction due to messed-up proteins or processes.
6. Cell Survival Impact:
– While cells might cope for a bit without it, prolonged absence would likely lead to problems in carrying out essential tasks, affecting cell survival and possibly leading to cell death.
In short, without the Golgi apparatus, a cell would struggle to modify proteins, transport materials, secrete necessary substances, handle waste, and function properly. It’s like losing a vital “organizer” within the cell, making its life a lot more challenging.
