Answer:

A. Phospholipid bilayer

Explanation:

Cell membrane is a selective permeable structure in all living cells that allows the passage of some molecules and disallows some. This function of the cell membrane is attributed to the PHOSPHOLIPID BILAYER CONTENT of its structure.

The phospholipid bilayer contains both a hydrophobic end (water fearing) and hydrophilic end (water loving). The interaction of the molecules with these regions of the membrane serves as the basis for the movement of molecules across the cell membrane.

All naturally occurring polysaccharides have one terminal residue, which contains a free anomeric carbon. Why do these polysacch

vekshin1

Answer:

Option (A).

Explanation:

Polysaccharides may be defined as the carbohydrates that can be hydrolyzed into large number of the single units. The polysaccharides are always non reducing in nature.

Although all polysaccharides have the anomeric carbon but they do not have the free aldehyde and ketone group. Their functional group is is involved in the formation of the glycosidic bond. For the sugar to show the reducing test, they must have aldehyde or kteone group and it is absent in case of polysaccharides.

Thus, the correct answer is option (A).

What is the function of the cell membrane? (4 points)

OlgaM077 [116]

Question 1
The function is the plasma membrane.
The microtubules.
The primary function of the cell membrane is to regulate what substances enter and leave the cell.
To monitor the amount of glucose needed by the cell: After washing your hands, insert a test strip into your meter.
Use your lancing device on the side of your fingertip to get a drop of blood.
Touch and hold the edge of the test strip to the drop of blood and wait for the result.
Your blood glucose level will appear on the meter's display.
