The very function, or job of CELL MEMBRANES is to protect the cell from it's surroundings, or in other words, to keep it safe. It controls the movement of substances in and out of cells and organelles, like a guard watching for suspicious activity and protecting something.

The cell membrane itself is a thin, flexible layer around the cells of all living things. It separates the inside of the cells from the outside of the cells.

When comparing proteins and polysaccharides, the following similarities

lianna [129]

Answer:

The comparison of proteins and polysaccharides establishes that they have similarity in both consist of linked monomers via the process dehydration reactions.

Explanation:

Both proteins and polysaccharides are polymers whose structure consists of the union of monomers. In the case of proteins the monomer is the amino acid, while in the polysaccharides can be glucose molecules.

The process of polymer formation is called polymerization, and one of the reactions that this process allows is polycondensation, where a water molecule is lost in the union of monomers.

The loss of water in a chemical reaction involves dehydration, a characteristic shared by the processes of adding monomers to proteins and polysaccharides.

The other options are not correct, because

Hydrolysis produces the rupture of molecules, with the intervention of water.
Only polysaccharides are sugars bound by the dehydration synthesis process.
Only proteins consist of amino acids linked through the process of hydrolysis.

Which enzyme plays an important role in the conversion of arachidonic acid to leukotrienes?

bezimeni [28]

The enzyme is lipoxygenase.

Lipoxygenase is a variety of enzymes that can cause oxidation of fatty acids. There are several varieties of lipoxygenases, some of which are present in plants. They are involved in the formation of white blood cells that are involved in some severe allergic reactions (anaphylaxis). It is based on this knowledge that antiallergic drugs have been developed to inhibit the activity of lipoxygenase, including reducing inflammatory reactions.

Leukotrien are named thus because they were discovered in leucocytes and that they are unsaturated lipids with 3 conjugated double bonds (trienes) and 20 carbon atoms
