Answer:

how does a cell work

Explanation:

In the eukaryotic cell, the DNA is surrounded by a membrane constituting the nucleus. The cytoplasm is highly varied and rich in different cellular organelles. ... It is a layer composed of proteins and phospholipids whose function is to separate the interior from the exterior of the cell and exchange substances.

Lelu [443]

Answer:

The increase in volume of the muscle fibers due to the enlargement of its components is referred to as hypertrophy.

Explanation:

Hypertrophy is about increasing the size of the transverse diameter of muscle fibers, it causes the muscle to grow in volume, due to the stimulation of the growth of muscle cells without cell division in the muscle. Hypertrophy occurs as a result of resistance training.

The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one
netineya [11]

Answer:

The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one another , this happens because <u>the two sides of a cell membrane face different environments and carry out different functions. </u>

<u></u>

Explanation:

<u>PROTEINS , LIPID AND CARBOHYDRATES , all are the components of the plasma membrane , located at different sites .</u>

<u>PROTEINS -:</u> The main component of plasma membranes is proteins. Two key categories of membrane proteins are available: <u>integral and peripheral.</u> As their name implies, integral membrane proteins are incorporated into the membrane: they have at least one hydrophobic region that anchors them to the phospholipid bilayer's hydrophobic center. Others just stick partway through the membrane, while others extend from one side of the membrane to the other and on either side are exposed.

On the outside and inside surfaces of membranes, peripheral membrane proteins are found which are bound either to integral proteins or to phospholipids. Peripheral membrane proteins do not stick into the hydrophobic center of the membrane as opposed to integral membrane proteins, and appear to be more loosely bound.

<u>LIPID -:</u> Phospholipids, arranged in a bilayer, make up the plasma membrane 's essential cloth. Since they are amphipathic, they are well-suited for this function, meaning they have both <u>hydrophilic and hydrophobic regions.</u>

The hydrophilic or "water-loving" component of a phospholipid is its head, which includes a phosphate group that is negatively charged, as well as an additional small group that can also be charged or polar.

Its long, nonpolar fatty acid tails make up the hydrophobic, or "water-fearing," portion of a phospholipid. The tails of fatty acids can interact easily with other non-polar molecules, but interact poorly with water.

<u>CARBOHYDRATES</u> -: The main component of plasma membranes is carbohydrates. In general, they are located on the outer surface of the cells and are either bound to proteins (glycoproteins forming) or to lipids (glycolipids forming). These chains of carbohydrates can consist of 2-60 units of monosaccharide and can either be straight or branched.

Hence , the correct option is B.
