SpletAnswer: Lysosomes are organelles found in animal and plant cells that contain digestive enzymes. Their primary function is to break down waste materials and cellular debris such as proteins, lipids, carbohydrates, and nucleic acids. Lysosomes also play a role in digesting food particles that have been taken in by the cell through the process of ... SpletThe lysosome is the cell’s main digestive compartment to which all sorts of macromolecules are delivered for degradation. The structure of the lysosome is variable … SpletAs mentioned, lysosomes are also part of the endomembrane system. Lysosomes are specialized vesicles that bud off of the Golgi apparatus. A lysosome uses a pump within its membrane to transport high concentrations of H + into its lumen, thus lowering the internal pH.

"SpletDigestive enzymes of lysosomes are produced in the endoplasmic reticulum. These are active at acidic pH (approx. 5) that can hydrolyse proteins, polysaccharides and other nucleotides. These enzymes are called hydrolytic enzymes. After synthesizing, these enzymes go towards the Golgi machinery and form the vesicle, which is getting tagged by … " - The lysosomes

The lysosomes

SpletThe lysosome is commonly referred to as the cell's recycling center because it processes unwanted material into substances that the cell can use. Lysosomes break down this … SpletLysosomes are composed of soluble and transmembrane proteins that are targeted to lysosomes in a signal-dependent manner. The majority of soluble acid hydrolases are modified with mannose 6-phosphate (M6P) residues, allowing their recognition by M6P receptors in the Golgi complex and ensuing transport to the endosomal/lysosomal system.
