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.
Give the biological significance of cell respiration?
Every cell in the body requires energy. It derives the energy by oxidation of sugars, fatty acids and proteins. Humans and animals have lungs and a circulatory system to deliver oxygen to every cell, as well as removing Carbon Dioxide and cellular waste.
Building blocks of the cell?
A typical animal cell consists of a cytoplasm encased by a cell membrane. In the cytoplasm is:- a nucleus - stores genetic information- ribosomes - where proteinsythesis takes place- mitochrondria - for cellular respiration
Where does polyadenylation occur?
Polyadenylation occurs at the 3' end (the back) of an mRNA strand in the nucleus of the cell. This act of polyadenylation creates a polyadenine (polyA) tail. mRNA cannot leave the nucleus of the cell unless polyadenylation occurs. PolyA tails seem to protect integrity of the mRNA molecule, which is exposed to multiple proteins that can degrade it once shipped to the cytoplasm
How a cell membrane moves large particles into the cell?
Endocytosis Lol you go to IHS? Re: Lol, I'm just googling the questions for Mr. Elliott's homework, let's see. Bulk transport of substances out of the cell.. LOL im in IHS 2 im in Mr. elliotts class 2, did u guys graduate, and i wanna ask lower concentration of solutes outside the cell than inside, what is its prefix
Why is a cell able to perform all the function necessary?
On a cellular level, everything is driven by biochemistry. Nucleic acids synthesize proteins which catalyse reactions which bring about everything that a cell does.

What cellular organelle is responsible for packaging proteins that the cell secrets?
gulgi apparutus
Proteins in the cell membrane that identify the cell are called?
These proteins are called self markers. They tell the immune cells that they belong in the body and they should be attacked.Cell receptors (proteins) on the cell membrane mediate the inter cellular communications.
How a cell membrane moves large particles into a cell?
Through integral proteins (tube shaped proteins that have one opening in the extra cellular matrix and the other opening inside the cell).
What is the function of a lysosme?
LysosymesA membrane bound organelle that is responsible for degrading proteins and membranes in the cell, and also helps degrade materials ingested by the cell.
Cellular adhesion molecules are?
Cell adhesion molecules are groups of transmembrane proteins that mediate.
Which cellular is responsible for packaging the proteins that the cell secret?
The Golgi Body (also called the Golgi Apparatus) packages and ships cell products. They can be proteins as well as lipids.
Are proteins regulators of cell division?
DNA COPYING occurs in the presence of proteins thus it is necessary
What is lysosome job in a cell?
it breaks down cellular waste products, fats, and proteins. AKA its the garbage disposal in a cell
What connects cell membrane and cell wall in a plant cell?
A sort of dynamic cellular scaffolding that is made up of proteins, that can be rebuilt, or pulled apart by the cell.
What aids in cellular homeostasis by providing the main transport mechanism for proteins within the cell?
er
