Proteins in a membrane are __________.

Biology
2 answers:
jarptica [38.1K]4 years ago

Answer:

Proteins in a membrane are C. Both answer choice is true.

Explanation:

Membranes have different types of proteins. <em>Peripheral proteins are the ones that are placed on the inside suface held in place by the cytoskeleton. Integral proteins are the ones that are embedded in the membrane and protrude from either surfaces of the bilayer. </em>These integral proteins also can be carrier proteins, which facilitate passage of molecules through the membrane ; enzymatic proteins, whichcatalyze a specific reaction  or they can recognize pathogens, baing cell recognition proteins. In the membrane we can find aquaporins too, which are membrane channel proteins that enable water to cross a membrane.

Answer:

c. Both answer choices are true.

Explanation:

Peripheral proteins and integral proteins are a type of membrane proteins that play a vital role in signal transduction, enzyme activity, cell adhesion and transportation of molecules.

Peripheral proteins are attached to the lipid bilayer temporarily at either one side of the lipid bilayer and can be easily dissociated from the lipid bilayer when treated with polar solution. It plays an important role in transportation,  maintaining the shape of the cell as well as signal transduction.

Integral proteins span the two sides of the lipid bilayer and are attached to it permanently, it can only be detached by the treatment with non polar solutions. It plays an important role in cell adhesion and transportation.

A student plans to analyze a protein sample that he suspects to be made of 4 subunits that are non-identical but similar in mole
Butoxors [25]

Answer:

Agarose gel electrophoresis is the most suitable method for this analysis.

Explanation:

SDS-PAGE, sodium dodecyl sulfate polyacrylamide gel electrophoresis, is a procedure used for visualizing and separating proteins according to their molecular weight. The use of sodium dodecyl sulfate and polyacrylamide gel eliminates most of the influence of the tertiary structure and charge, and proteins are separated solely based on polypeptide chain length. So, if the student suspects that the protein sample is conformed of 4 subunits similar in molecular weight, SDS PAGE will likely not separate them.

On the other hand, an agarose gel electrophoresis can separate proteins based on their size AND charge, so, if you suspect that the proteins are not identical but similar in size, the charge factor can be important to separate them in an experiment.

Identify the characteristics of protists
zimovet [89]
Protist are eukaryotic organisms that cannot be classified as a plant animal fungus. They are mostly unicellular, but some like algae, are multicellular. Kelp, or “seaweed” is a large multicellular protist that provides food, shelter, and oxygen for numerous underwater ecosystems.
