What cell membrane structure allows water-soluble materials to be passively transported to the cytoplasm?

Biology
1 answer:
monitta3 years ago
3 0

Answer:

B. Carrier proteins

Explanation:

Water-soluble materials, such as glucose, amino acids, and ions, need help to cross the membrane because they are repelled by the hydrophobic tails of the phospholipid bilayer. The tails are not hydrophilic.

Endocytosis vesicles are an example of active transport, they require energy to allow large molecules to be taken into the cell through a system of vesicles.

Golgi complex vesicles deliver proteins and other macromolecules outside of the cell from the inside.

Carrier proteins can participate in both active and passive transport across cell membranes. For example, carrier proteins with channels can help molecules cross the membrane passively.

Why is it important that saline solution has a specific concentration when a person is put on an IV drip of saline?
timurjin [86]

Answer:

Doctors utilize IV saline for refilling lost fluids, flushing wounds, providing medication, and maintaining patients through surgery, dialysis, and chemical treatment. As a fashionable therapy, Saline IVs even found a space outside the hospital.

"There are significant quantities of sodium and chloride, higher than blood levels.

Explanation:

The solution of sodium chloride-water, generally known as saline, is the saline solution. It is the intravenous fluid most usually used. It was utilized since the early decades of the 19th century and is used annually in the United States alone with more than 200 million liters.

Though about 60 percent of the body consists of water, it is not possible to inject water into the blood alone, because the blood could lead to the depletion of important electrolytes.

Direct water injection into the bloodstream would likewise lead to the blood cells' osmotic impact.

Blood cells, which are predominantly salty, will take water and cause it to expand quickly until the cell membrane breaks down. The content of the cells would then leak into the plasma. A substantial proportion of body cells can be damaged to death. Death can result.

There would be no permanent harm to a little amount of water injected into the blood directly. The bigger the number of cells injured, in essence, the more water injects into the circulation.

Water is blended in a solution in sodium and chlorine at approximately the same concentration as blood plasma to avoid damages caused by pure distilled water on blood cells. The outcome is that the solution splits the circulating volume with the cellular fluid and becomes an integral part of the circulating volume without a detrimental influence on blood cells.
