What is the role of glucose in catabolite repression? What is the role of glucose in catabolite repression?
Ierofanga [76]

Answer:

It decreases the levels of cAMP in the cell, repressing transcription from the lac operon.

Explanation:

When glucose is absent, cAMP serves as coactivator binds to CRP, the catabolite gene activator protein. The CRP-cAMP complex binds to the site near the lac promoter and stimulates the expression of the operon by RNA polymerase many folds.

Catabolite repression refers to inhibition of the synthesis of enzymes of lactose catabolism when glucose is present as an energy source. In the presence of glucose, synthesis of cAMP is inhibited resulting in its lower cellular concentration. The lower cAMP levels do not allow the binding of cAMP and CRP. The result is reduced expressed of lac operon.

9. What are mutations, and how do they increase the genetic variation within a species?
leva [86]

Mutations are changes that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke.

They increase the genetic variation within a species because they can create entirely new alleles in a population, random mating, random fertilization, and recombination between homologous chromosomes during meiosis which reshuffles alleles within an organism's offspring.

Compared to a cell with few aquaporins in its membrane, a cell containing many aquaporins will A. have a faster rate of osmosis
Aloiza [94]

The correct option is A: have a faster rate of osmosis

A cell containing many aquaporins will have a faster rate of osmosis.

Aquaporins are micro water channels within the membrane that allow for the exchange of water and other neutral molecules over the biological membranes of other organisms.

Due to the presence of Aquaporins in plants, they have a high diversity of regulation properties, localizations, and transport selectivity.

The rate of osmosis increases as the aquaporins facilitate the transfer of water at a faster rate.
