Answer:
As eukaryotic parasites will be more common in structure to the human body hence, the drugs might have adverse effects on the human body.
A large number of proteins found in the eukaryotic parasite will be similar to the proteins made by the human body. The drug taken for a eukaryotic parasite can harm the same kind of protein found in the human body.
Bacteria is a very small microorganism and has very simple machinery. The proteins formed by a bacterial cell are very few and are not as commonly related to the human proteins as the eukaryotic parasites. Hence, drugs taken for bacterial parasites would not have such adverse effects.
Answer:
D. Allosteric activator
Explanation:
In an enzyme, the allosteric site is a site/motif different from the active site, (i.e., the site with catalytic activity) which is able to interact with regulatory effector molecules in order to activate or inhibit enzymatic activity by influencing the tridimensional (3D) structure of the enzyme. An allosteric activator is an effector molecule with the ability to bind to a specific enzyme at a different site than the active site, thereby modifying the shape of the enzyme and increasing the affinity of this enzyme for its substrate. Moreover, Adenosine monophosphate (AMP) is a nucleotide composed of a phosphate group, a sugar ribose, and an Adenine (A) base. This effector molecule (AMP) has shown to allosterically stimulate diverse enzymes in physiological conditions (e.g., AMP-activated protein kinase).
Explanation:
The phenotypes and genotypes of the progeny can be determined by a dihybrid cross of the parents.
The heterozygous male will have the genotype 'SSww' and the heterozygous female will have the genotype 'ssWW'.
When crossed, the F1 offsprings will have a hybrid genotype of 'SsWw'. These offsprings are heterozygous with spotted skin and wooly hair.
On self-crossing of the F1 hybrids, we find four different combinations of the alleles- SW, Sw, SW and sw. The probability of getting each of these combinations is 1/4.
Hence, the probability of any dihybrid type is 1 out of the 16 possible genotypes. Using Punnet square, we find
9 SSWW: 3 SSww: 3 ssWW : 1 ssww
This is the phenotypic ratio of the offsprings.
The ratio of the possible genotypes will be 1:2:1:2:4:2:1:2:1.
Answer:
B. 5
Explanation:
5 Although neither enzyme has its maximum catalyzing rate at 5, they are equal in their rate of catalyzing ability at this pH. Pepsin has an optimal pH of 3 while trypsin has an optimal pH of 8.
