If the metabolism of a cell suddenly slowed down so that there was less cellular energy available, which role of the cell membra

Answer:

The correct answer would be the active transport across the cell membrane.

The main functions of the cell membrane are a barrier, regulates transport (passive, facilitated, and active), the presence of receptors et cetera.

Only active transport (such as sodium pump, calcium pumps et cetera) requires the input of energy (ATP) for proper functioning. It uses energy to pump substances against the concentration gradient.

Thus, only active transport would be affected if less cellular energy is available.

WILL MARK BRAINLIEST FOR BEST AND ACCURATE ANSWER!<br><br> What are the three parts of a nucleotide?
nasty-shy [4]

<u><em>The nitrogenous base</em></u> is the central information carrying part of the nucleotide structure. These molecules, which have different exposed functional groups, have differing abilities to interact with each other.

<u><em>The second portion of the nucleotide is the sugar.</em></u> Regardless of the nucleotide, the sugar is always the same. The difference is between DNA and RNA. In DNA, the 5-carbon sugar is deoxyribose, while in RNA, the 5-carbon sugar is ribose. This gives genetic molecules their names; the full name of DNA is deoxyribonucleic acid, and RNA is ribonucleic acid.


<u><em>The last part of nucleotide structure, the phosphate group</em></u>, is probably familiar from another important molecule ATP. Adenosine triphosphate, or ATP, is the energy molecule that most life on Earth relies upon to store and transfer energy between reactions. ATP contains three phosphate groups, which can store a lot of energy in their bonds. Unlike ATP, the bonds formed within a nucleotide are known as phosphodiester bonds, because they happen between the phosphate group and the sugar molecule.

A protein channel in a hydrogen ion pump is shown below. What would happen if the concentration of H+ ions were higher inside th
inessss [21]

Answer:

The H+ ions moves outside.

Explanation:

The H+ ions moves outside the mitochondria of the cell if the concentration of H ions were higher inside the mitochondrion than outside environment of the mitochondrion in order to equalize the pH or H+ ions concentration of both inner side of mitochondria and outer side environment. This movement of H+ ions from a region of higher concentration to the region of lower through a semi-permeable membrane is known as osmosis which has a positive effect on the cell as well as organelles of the cell.

What it mean for something to be hypertonic?
Nady [450]
Hypertonic is where the solution has a lower water potential than the other side of the membrane. It has less water molecules and osmosis may occur under that in the presence of semi permeable membrane. Where water will flow from a higher water potential to lower water potential region
