Answer:
X is negative heterotropic modulator
Explanation:
In allosteric regulations, modulators are molecules that causes a change in the conformation of an enzyme, hence, resulting a change in enzyme activity. It can lead to a decrease or an increase of the enzyme. When a molecule decreases the enzyme activity it called a negative modulator, when it increases or activates the enzyme activity, it is called a positive modulator.
A positive or negative modulator can either be homotrophic (substrate acts as modulator) or heterotropic (another ligand acts as modulator).
In the example above, X is negative heterotropic modulator, because the modulator is different from the substrate and it also decreases the enzyme activity.
Answer:
A
Explanation:
The correct answer choice is not B,C, or D so it should be A
Future generations will have the same frequencies of the A and a alleles as generation 2. Individuals with the aa genotype could be produced.
Answer:
Carbohydrates - monosaccharides
Proteins - amino acids
Nucleic acids - nucleotides
Lipids - fatty acids (hydrocarbon chains)
Explanation:
There are four major biological molecules called biomolecules in nature namely; carbohydrates, proteins, nucleic acids and lipids. These four molecules form the bedrock upon which life is built. The biomolecules mentioned above are POLYMERS formed as a result of the combination of two or more simpler molecules called MONOMERS in a process called CONDENSATION.
The monomer of each polymeric biomolecule is as follows;
Carbohydrates - monosaccharides
Proteins - amino acids
Nucleic acids - nucleotides
Lipids - fatty acids (hydrocarbon chains)
Answer:
C) In 1946, the Argentinian government imported fifty beavers from Canada, which were to be released in Cami Lake with the intention of creating a commercial fur trading industry. Though a viable industry ultimately failed to materialize, the introduction of the beavers into the region has had far-reaching consequences.
