What structures in the plasma membrane regulate ion passage?

2 answers:

4 0

Integral proteins are embedded in the phospholipid layer, and can sometimes form protein channels that let ions and other small molecules through.

Answer:

The correct answer is integral membrane proteins.

Explanation:

The plasma membrane is the outer membrane of the cell which is selectively permeable. The small polar molecules and hydrophobic molecules can go through the lipid bilayer, but ions and large polar molecules cannot go through. There are some Integral membrane proteins present in the plasma membrane that enable ions to pass through the plasma membrane by active or passive transport.

Thus, the correct answer is integral membrane proteins. Ions generate electrochemical gradient so they are generally used in secondary transport systems.

Thus, the correct answer is integral membrane proteins.

Your ability to process language in the left hemisphere of the brain and handle spatial thinking in the right hemisphere of the

DerKrebs [107]

According to the research, the correct option is lateralization. Your ability to process language in the left hemisphere of the brain and spatial thinking in the right hemisphere of the brain is called lateralization.

<h3>What is lateralization?</h3>

It refers to the functional differentiation that exists in the human brain, that is, it is made up of the functions and processes that are specific to each hemisphere and, therefore, the capacities that are carried out predominantly through one hemisphere.

The hemispheres are interconnected through bundles of neuronal fibers that belong to the corpus callosum and, despite this, the left hemisphere performs a set of different functions with respect to the right and vice versa.

Therefore, we can conclude that according to the research, the correct option is lateralization. Your ability to process language in the left hemisphere of the brain and spatial thinking in the right hemisphere of the brain is called lateralization.

Why do scientists prefer to have more than one theory about something

Advocard [28]

Having one theory is setting a limit on your potential and the potential of the overall theory and subject you are working on. Having multiple theories gives you a broader idea and perspective of what is going on, and even though one may slightly contradict the other, it is okay because that is what theories are for.

To the point, scientists usually have more than one theory so that they can gain a broader perspective on the matter and maybe even increase the chance of being correct on the matter.

Hope this was helpful.

Cheers,

The shape of the cell changes in_______

LiRa [457]

Answer:

Its Euglena

Explanation:

Shape change from normal elongated egg-shape to round-shape in stressful environment. These shape changes attain two transition phases. The I-transition phase is reversible where the organism can return to normal if favourable environment persists.
