WebO Cells produce defective lysosomal proteases, which break down proteins inefficiently. Chondroblasts (cells in cartilage) sequester collagen-building enzymes within lysosomes. The lysosomes in cartilage tissue cannot fuse with protein-containing vesicles. Excess lysosomal proteases are produced and released extracellulary, where they degrade WebWhy are lysosomes considered the “garbage trucks” of a cell? (a) Because they transport materials between two cell organelles. (b) Because they pump materials from outside to the inside of a cell. (c) Because they remove all unwanted cellular materials. (d) Because they transport materials from one cell to another.

WebIn a process known as phagocytosis or endocytosis, a section of the plasma membrane of the macrophage invaginates (folds in) and engulfs a pathogen. The invaginated section, with the pathogen inside, then pinches itself off from the plasma membrane and becomes a vesicle. The vesicle fuses with a lysosome. The lysosome’s hydrolytic enzymes ... Web18 nov. 2024 · Lysosomal degradation of RTKs plays an important role in regulating proliferation. Ligands that bind to epidermal growth factor receptor (EGFR) can recruit the adaptor protein Grb2, which binds to Cbl E3 ubiquitin ligase. EGFR is ubiquitinated by Cbl and then trafficked to the lysosome for degradation [28, 29]. first grade sentences to copy
