Glyoxysomes

 

Glyoxysomes – Fat-to-Sugar Converting Organelles

1. Definition and Structure
Glyoxysomes are membrane-bound organelles that are a special type of microbody.
They contain specific enzymes that help in the conversion of fatty acids into sugars.

2. Function and Importance
The main function of glyoxysomes is to convert stored fats into usable sugars through a biochemical pathway called reverse glycolysis(the breakdown of glucose by enzymes, releasing energy and pyruvic acid-a key molecule in cellular metabolism).

This process is especially important in germinating seeds, where the young plant cannot perform photosynthesis yet.

3. Role in Germination (the process by which a plant grows from a seed into a seedling) (अंकुरण, मोड येणे, रुजवात.)

During germination:

• The seed uses stored fats as a source of energy.

• Glyoxysomes help in converting these fats into glucose (sugar), which the growing plant uses to carry out its life processes.

• This continues until the seedling develops leaves and begins to photosynthesise on its own.

Conclusion
Glyoxysomes are crucial for early plant development, especially in seeds rich in oil. By converting fats into sugars, they ensure the plant has enough energy to grow before it starts making its own food through photosynthesis.
