Enzymes are pH and temperature specific.Which model shows the relationship between the reaction of velocity of an enzyme and tem
sasho [114]

Answer:

The rate at which an enzyme catalyses a particular reaction is calculated by the amount of substrate being used up. The concept of a chemical reaction is that the substrate is converted into product with the help of an enzyme.

Rate of reaction= Amount of substrate utilized or product formed/ Time taken

Explanation:

Temperature is an important factor in the deciding of a rate of reaction. The velocity of an enzyme <u>increases with an increase in temperature</u> until and optimum temperature is achieved. After that, the velocity of an enzyme starts <em>decreasing</em> since the enzyme starts to get denatured.

Enzymes work best at a <em>specific pH</em>. If there are changes in pH, the active site of an enzyme gets modified and the rate of reaction decreases. Certain enzymes like pepsin which is in our stomach works at an acidic pH of 2.0.

If one parent has type B blood and the other type O blood what percentage of the child's blood will be B, O, A?
kirill115 [55]

Answer:

If one parent has blood type B and the other parent has blood type O, the percentage of the blood type of the offspring will depend on the genotype of the parent with blood type B.

Explanation:

Knowing the blood type of the offspring of the cross between parents with blood type B and O raises two possible scenarios, depending on whether the genotype of the parent (type B) is B|B or B|O.

Blood type is an inherited trait and is characterized by the presence or absence of surface antigens A and B in the red blood cells, which genetically behave as co-dominant traits.

  • <em>Blood type A</em><em> contains antigen A and its genotype can be A|A or A|O. </em>
  • <em>Blood type B </em><em>contains the B antigen, whose genotype can be B|B or B|O. </em>
  • <em>Blood type AB </em><em>contains both antigens and a single A|B genotypic expression. </em>
  • <em>Type O blood lacks surface antigens, and is the recessive trait so its genotype is O|O.</em>

<u>Scenario 1: Parent with genotype B|B.</u>

In this case, knowing that the genotype for type O is always O|O, all offspring would be of blood type B, genotype B|O.

B|B X O|O

Alleles    B    B

O          B|O B|O

O          B|O B|O

100% of the offspring would be of blood type B.

<u>Scenario 2: Parent with genotype B|O.</u>

In this case, 50% of the offspring will have blood type O and 50% B.

B|O X O|O

Alleles    B    O

O           B|O O|O

O           B|O O|O

In no scenario would offspring of blood type A be possible.
