Are there options to chose from? Like multiple choice answers?? If So, I can try and Answer for you :)
Answer: billions of types of proteins
The frequency of allele is illustrated as the ratio of that specific allele in the population. As one knows that as the humans are diploid, so the total number of alleles is double of the total number of people in the population.
In order to determne the allele frequencies for A and B, there is a need to know that the persons with type A blood are homozygous AA, the persons with type AB blood are heterozygous AB, and the persons with type B blood are homozygous BB.
The frequency of A is:
2*(number of AA) + (number of AB) divided by 2 * (total number of individuals)
Therefore,
{2 * (200) + (75)} / 2 (200 +75 +25)
This comes out to be 475/600 = 0.792. Thus, p = 0.792.
Since, q is 1 - p
Then, q = 1 - 0.792 i.e 0.208.
Answer:
Carbonic anhydrase being a catalytic enzymes, facilitates the reaction by decreasing the amount of energy needed to complete the reaction.
Explanation:
The above enzyme Carbonic anhydrase facilitates the reaction between carbon dioxide and water. High concentration of carbon dioxide in the blood triggers this reaction. The reaction results in the formation of carbonic acid which is again reversed into carbon dioxide and water when blood reaches the lung. The carbon dioxide is exhaled through expiration. As carbonic anhydrase is a catalyst, hence it lowers the requisition of energy for transitional and activation phase of the reaction. This also account for fastest action of carbonic anhydrase enzyme with very high rates of reaction.
