Understanding Cellular Waste Disposal: Exudates, Endocytosis, Autophagy, Apoptosis, and Necrosis

Exudates are substances that pass through the cell membrane and are released outside the cell. These can include hormones, enzymes, toxins, and other signaling molecules.

Ques 2. What is endocytosis ?
Ans. Endocytosis is a process in which cells engulf external particles or substances and bring them inside the cell. This can be used for nutrient uptake, immune response, or cell signaling.

Ques 3. What is autophagy ?
Ans. Autophagy is a process in which cells break down and recycle their own components, such as proteins and organelles, to maintain cellular homeostasis and survive under stress conditions.

Ques 4. What is apoptosis ?
Ans. Apoptosis is a programmed form of cell death, which involves the breakdown of cell components and the elimination of the dead cell. This process is important for maintaining tissue homeostasis and preventing cancer.

Ques 5. What is necrosis ?
Ans. Necrosis is a form of cell death that occurs due to injury, infection, or other forms of cellular stress. Unlike apoptosis, necrosis is not a programmed process and can lead to inflammation and tissue damage.
