What roles do membrane proteins play in making the cell membrane selectively permeable?

Biology

levacccp [35]3 years ago
5 0
Cell membranes contain membrane proteins that  allows all the interaction that occurs within the cell. It makes the cell membrane selectively permeable because of its characteristics as being fluid or its fluidity which means to say that they can move freely within the lipid bilayer. The membrane proteins can also be stored in the lipid bilayer together with the enzymes. It cannot be denied that membrane proteins have a lot of functions based on its type. They can be integral proteins, peripheral proteins and lipid bound proteins.

The correct answer is -

1. right-handed

2. right-handed

3. positive

4. left-handed

5. negative

6. negative

Explanation:

In a circular bacterial chromosome, the structure of DNA is a right-handed double helix In a circular bacterial chromosome.

If DNA is twisted in the right-handed direction, it becomes overwound. Overwinding results in positive supercoiling takes place. If DNA is twisted in the left handd direction, it becomes underwound. Underwinding results in negative supercoiling.

f. One effect  negative supercoiling in bacterial chromosomes is to promote separation of the two strands of DNA in the double helix

1. Which of the following statements are true?
hammer [34]

Your answers would be:

1. ---- B. A cell cannot be subdivided into smaller units that maintain the living state.

2. ---- The organism is a eukaryote because it has a nucleus.

3. ---- D. Water would flow into them because they are hypertonic to external environment.

If you want to know why:

1. The cell is the basic unit of life or in other words, its the smallest unit that makes up a living thing. It does not subdivided further if you are talking about sustaining life. Yes, it is made up of smaller units of organelles, but these organelles work together as a single unit (as a cell), to do life sustaining processes.

2. The organism is a eukaryote because of the presence of a nucleus. This is one of the main features of a eukaryote that differentiates it from a prokaryote. Prokaryotes to not have a true nucleus.

3. Water would flow into them, causing the cell to swell and eventually burst if the concentration of solutes would not even out before then. The process of osmosis is what brings the water into the cell. The cell would have a higher solute concentration than freshwater. Through osmosis, the water would then go to the area of higher concentration, which would be the cell.
