A macromolecule is a large molecule present in the cell, composed of a huge number of monomer units with the various functions. There are four main groups: proteins (monomers are amino acids), nucleic acids (monomers are nucleotids) , lipids (monomers are free fatty acids) and carbohydrates (monomers are simple sugars such as glucose).
Some of their functions:
• Provide structure on the cellular levels-lipids (phospholipids) are the main components of the cell membrane;
• store genetic material-nucleic acid (DNA, RNA) are the carriers of genetic information
• store energy-starch is energy source in plants;
• enzymes -proteins often are with the functionin metabolism
• etc.
The way in which consumers<u> </u><u>most benefit </u>from a perfectly competitive undifferentiated market compared to a monopolist competition is that this kind of market will produce lower prices.
An increase in the<u> number of choices</u> as well as the<u> amount of marketing</u> can be considered consumer benefits of a perfectly competitive market in that the increased competition will force companies to expand into new products and invest more towards marketing in an effort to attract consumers, thus making it easier for said consumers to find their desired product.
on the other hand, a monopoly is when a <u>single controlling entity </u>has ownership of<u> all or almost all of the producing companies for a specific product</u>, causing an absence of competition and thus eliminating the need for competitive pricing. Though the benefits mentioned before are good for consumers, the greatest benefit is in the reduction in prices caused by a competitive market, allowing much greater access to a wider variety of goods for all of the economic classes.
