Organelles function in the destruction of nonfunctional organelles?
Autophagosomes are involved in the process of removing nonfunctional organelles. They engulf the targeted organelles and fuse with lysosomes to degrade their contents. This process helps maintain cellular health and function by recycling components for reuse.
What fuses with food vacuole and digests contents?
Lysosomes fuse with the food vacuole to digest its contents. Lysosomes contain enzymes that break down macromolecules such as proteins, carbohydrates, and lipids into smaller molecules that can be used by the cell for energy or building materials. This process is known as intracellular digestion.
Where would old cell organelles be broken down or digested to be recyled in the cell?
This occurs during a process called autophagy. Autophagosomes encircle damaged or old organelles. they then fuse with lysosomes where these organelles are broken down and digested. This takes place in the lysosome.
The lysosomes is formed from?
The synthesized enzymes in the rough endoplasmic reticulum are released from Golgi apparatus in small vesicles and fused with acidic vesicles. These acidic vesicles are called endosomes and they become lysosomes.
What are the types of lysosomes?
The two types of lysosomes are Peroxisomes which is a vesicle containing oxidases and catalase. It's located by the smooth ER of the animal cell. The second type of lysosme is the Proteasome which is a tiny barrel-shaped structure that contain proteases. Peroxisomes functions include oxidizing amio acids and fatty acids; also detoxifing alcohol. The functions of Proteasome includes degrading unneeded, damaged, or faulty proteins by cutting them into small peptides.

Where are organelles digested?
Probably lysosomes fuse and digest most organelles.
Where does autophagy happen?
Autophagy primarily occurs within the cell's cytoplasm. It is a process of cellular self-degradation where damaged organelles and proteins are engulfed by autophagosomes, which then fuse with lysosomes for degradation. This process helps maintain cellular homeostasis and provide nutrients during times of stress.
Why lysosomes are called polymorphisomes?
Lysosomes are sometimes referred to as polymorphisomes because they can exhibit a variety of shapes and sizes depending on their contents and the stage of their function. This variability allows them to adapt to different cellular processes, such as digestion and waste removal, by altering their morphology. Additionally, the term reflects their dynamic nature, as lysosomes can fuse with other organelles and participate in various metabolic pathways.
What is the difference between primary and secondary lysosomes?
Primary lysosomes are newly formed vesicles containing digestive enzymes, while secondary lysosomes are formed when primary lysosomes fuse with endocytic vesicles containing material to be digested. Essentially, primary lysosomes are the initial structures while secondary lysosomes are the active, digestive forms.
What fuses with food vacuole and digests contents?
Lysosomes fuse with the food vacuole to digest its contents. Lysosomes contain enzymes that break down macromolecules such as proteins, carbohydrates, and lipids into smaller molecules that can be used by the cell for energy or building materials. This process is known as intracellular digestion.

This occurs during a process called autophagy. Autophagosomes encircle damaged or old organelles. they then fuse with lysosomes where these organelles are broken down and digested. This takes place in the lysosome.
What is the main role of lysosomes in process of food digestion?
Lysosomes are membrane-bound organelles that contain digestive enzymes responsible for breaking down macromolecules, including proteins, lipids, and carbohydrates, into their smaller components. In the process of food digestion, lysosomes fuse with phagosomes or autophagosomes, which contain engulfed food particles or damaged cellular components, facilitating the degradation of these substances. This allows the cell to recycle nutrients and eliminate waste, playing a crucial role in cellular metabolism and homeostasis.
What organelle breaks down toxins in the cell?
The liver breaks down toxins by producing bile which will disintegrate toxins that are in the body. This will facilitate the process of metabolism.
What are the organelles that contain digestive chemicals?
Digestive (hydrolytic) enzymes are stored in lysosomes, which will fuse with a food vacuole.
What function does lysosomes perform in a cell?
Lysosomes degrade proteins. The kind of proteins they degrade are brought into the cell by endocytosis - they do not degrade proteins that are resident in the cell, proteasomes do that . Lysosomes fuse with the protein to be degraded and release the special class of enzymes they carry, hydrolases, that do the actual break down process. Lysosomes are also the key factor in ridding a cell of H2O2 in a cell, hence the hydrolases.
Where are lysomes synthesised in a cell?
Enzymes of the lysosomes are synthesized in the rough endoplasmic reticulum and carried to Golgi apparatus which will release them in small vesicles which ultimately fuse with acidic vesicles called endosomes, thus becoming full lysosomes.
