Why does the structure of the plasma membrane make this type of transport neccesary for fluids

Biology
1 answer:
Lina20 [59]2 years ago
8 0

Explanation:

Both phospholipid molecules and embedded proteins are

able to diffuse rapidly and laterally in the membrane. The

fluidity of the plasma membrane is necessary for the

activities of certain enzymes and transport molecules

within the membrane .and also The plasma membrane, or the cell membrane, provides

protection for a cell. It also provides a fixed environment

inside the cell, and that membrane has several different

functions. One is to transport nutrients into the cell and

also to transport toxic substances out of the cell .

The unequal distribution of charges across the cell membrane results in the ______________.
sdas [7]
<span>This result is produced by the selective permeability of the plasma membrane when the presence of negatively charged ions does not diffuse into the cell and the action of several sodium-potassium pump units causes an unequal distribution of charges through the membrane.</span>

A protein that contains more isoleucine, phenylalanine and leucine than asparagine, lysine and arginine is most likely ________.
Snezhnost [94]

Answer:

The correct answer is: Hydrophobic, Hydrophobic.

Explanation:

  • Proteins are made up of polypeptide chains which are formed by the polymerization of amino acid molecules, linked together by peptide bonds.
  • The amino acids can be broadly classified into non-polar and polar.
  • The non-polar amino acids can be defined as those amino acids whose side chains possess hydrocarbon molecules only. They do not possess any charge and are incapable of forming hydrogen bonds with water molecules. They tend to avoid water and so they tend to remain buried into the interior of a protein. Examples can be illustrated as Leucine, Valine, Isoleucine, Phenylalanine, etc.
  • The polar amino acids can be defined as those amino acids whose side chains either possess a charge (positive or negative) or a hydroxyl group which is capable of forming hydrogen bonds with water molecules. As they tend to form hydrogen bonds with water molecules they are usually found on the surface of the proteins. Examples can be illustrated as Lysine, Arginine, Serine, Asparagine, etc.
