Question about centrosomes and lysosomes. I think?

Question

A know either a centrosome of a lysosomes get's rid of wastes in the cell.

My two IMPORTANT questions are. Please help!!!

Which one removes waste? Centrosome of lysosome?

Does it use high or low pressure to remove waste? How does it remove waste?

Answer as much as you can. Thanks-

Answer 1

Lysosomes are membranous sacs of hydrolytic enzymes that an animal cell uses to digest all kinds of macromolecules. These enzymes work best in acidic enviroments. Lysosomes carry out intracellular digestion in a variety of ways.

Phagocytosis is one way. Another way is that Lysosome use their hyrolytic enzymes to recycle the cells own organic material, this is called autophagy.

Answer 2

The centrosome is the main organizational center in the cell for microtubule assembly. Degradation of proteins and other compounds takes place in the lysosome. The lysosome is a specialized organelle that contains a number of different hydrolases, most of which work at lower than physiological pH. A proton pump in the membrane of the lysosome leads to a lowering of the pH and the subsequent activation of the lysosomal enzymes. This can be shown by using drugs that either poison the proton pumps or other drugs that non-specifically inhibit the lowering of the pH (such as ammonium chloride). Vesicular structures in the cell are routinely sorted through a constant movement of fusion and separation, such that endosomes, multivesicular bodies and lysosomes create almost a continuum of vesicular compartments.

Answer 3

I'm a med student but i remember a little of bio, well the one that stores waste is the lysosome .And it gets rid of it by fagocytosis, wich is the change of hipertonic solut. in the concentration of the cell membrane.
How the waste gets tracked by the lysosome is still a mystery in modern microbiology.

Answer 4

The answer is the lysosome.
Lysosomes: a bag of hydrolytic enzymes. pH of 5 is optimum and is maintained by the continuous pumping of H ions into the vesicle. They are produced by the trans face of the Golgi Apparatus. Their functions include, intracellular digestion, autophagy, and programmed destruction. In humans Tay-Sachs disease is caused by a lack of lipid digesting enzymes and an accumulation of lipids in the brain. Pompe's disease deals with carbohydrate enzymes and ultimate liver damage.

By the way Ray what medical school do you go to? fagocytosis? Try phagocytosis.

Answer 5

the answer is lysosome. lysosome is like the "stomach" of the cell, it uses enzymes to "digest" or break down the waste

Answer 6

lysosome

Answer 7

One of the major functions of lysosomes is the digestion of material taken up from outside the cell by endocytosis. However, the role of lysosomes in the digestion of material taken up by endocytosis relates not only to the function of lysosomes but also to their formation. In particular, lysosomes are formed by the fusion of transport vesicles budded from the trans Golgi network with endosomes, which contain molecules taken up by endocytosis at the plasma membrane. The formation of lysosomes thus represents an intersection between the secretory pathway, through which lysosomal proteins are processed, and the endocytic pathway, through which extracellular molecules are taken up at the cell surface (Figure 9.36). Material from outside the cell is taken up in clathrin-coated endocytic vesicles, which bud from the plasma membrane and then fuse with early endosomes. Membrane components are then recycled to the plasma membrane and the early endosomes gradually mature into late endosomes, which are the precursors to lysosomes. One of the important changes during endosome maturation is the lowering of the internal pH to about 5.5, which plays a key role in the delivery of lysosomal acid hydrolases from the trans Golgi network. Figure 9.36 Acid hydrolases are targeted to lysosomes by mannose-6-phosphate residues, which are recognized by mannose-6-phosphate receptors in the trans Golgi network and packaged into clathrin-coated vesicles. Following removal of the clathrin coat, these transport vesicles fuse with late endosomes, and the acidic internal pH causes the hydrolases to dissociate from the mannose-6-phosphate receptor (see Figure 9.36). The hydrolases are thus released into the lumen of the endosome, while the receptors remain in the membrane and are eventually recycled to the Golgi. Late endosomes then mature into lysosomes as they acquire a full complement of acid hydrolases, which digest the molecules originally taken up by endocytosis. Phagocytosis and Autophagy In addition to degrading molecules taken up by endocytosis, lysosomes digest material derived from two other routes: phagocytosis and autophagy (Figure 9.37). In phagocytosis, specialized cells, such as macrophages, take up and degrade large particles, including bacteria, cell debris, and aged cells that need to be eliminated from the body. Such large particles are taken up in phagocytic vacuoles (phagosomes), which then fuse with lysosomes, resulting in digestion of their contents. The lysosomes formed in this way (phagolysosomes) can be quite large and heterogeneous, since their size and shape is determined by the content of material that is being digested. Figure 9.37 Lysosomes are also responsible for autophagy, the gradual turnover of the cell’s own components. The first step of autophagy appears to be the enclosure of an organelle (e.g., a mitochondrion) in membrane derived from the ER. The resulting vesicle (an autophagosome) then fuses with a lysosome, and its contents are digested (see Figure 9.37). Autophagy is responsible for the gradual turnover of cytoplasmic organelles.
