Question

All Enzymes are:
A. Enzyme precursors
B. Similar enzymes formed from different genes
C. Different enzymes of an enzyme system
D. Anti Enzymes

Answer 1

It is the opposite of an isoenzyme. It is coded by different alleles that are present at the same locus.

Step by step answer: Allozyme is the opposite of an isoenzyme. They are coded by different alleles that are present at the same locus. The two enzymes catalyze different types of reactions.
All Enzymes are common biological enzymes. They exhibit high levels of functional evolutionary conservation throughout specific phyla and kingdoms. They are used by scientists who study phylogenetics as a molecular marker to gauge and frame evolutionary history and relationships between different species.
This can be done because allozymes do not share the same structure. Hence, they can be separated by the process of capillary electrophoresis. However, some species are monomorphic for many of the allozymes (same structure in all the similar species). This would make it difficult for phylogenetic scientists to assess the evolutionary histories of these species. Hence, in these instances, phylogenetic scientists use another method to determine the evolutionary history and links of different species
These enzymes generally perform very basic and primitive functions that are found commonly throughout all lifeforms. For example, DNA polymerase is the enzyme that repairs and copies DNA during DNA replication. Significant changes in this enzyme in different organisms reflect the significant events in the evolutionary history of these organisms. The DNA polymerase shows a relatively small difference in its amino acid sequence between the various phyla and kingdoms as expected
Correct Answer: Option B: Similar enzymes formed from different genes
Note: Enzyme precursors are known as zymogens. They are inactive and they don’t perform their specific functions. For example, pepsinogen is secreted from the chief cells of the fundus and body of the stomach. It is activated to form pepsin by the acidic pH formed by HCl. Anti Enzymes are the antibodies or enzymes that counteract the effects of a specific enzyme.
