Which of the following statements best helps explain the reaction specificity of an enzyme?
irakobra [83]

Answer:

This question lacks options, the options are:

A) The free energy of the reactants is greater than the free energy of the products.

B) The equilibrium constant of the reaction is much greater than 1.

C) The shape and charge of the substrates are compatible with the active site of the enzyme.

D) The concentration of the enzyme inside living cells is greater than the concentration of substrate.

The answer is C

Explanation:

An enzyme is a proteinous molecule that increases the rate of reaction of a biochemical reaction in living organisms. However, a protein molecule contains amino acids which makes up it's primary structure. An enzyme performs it action by binding to it's substrate using it's active site.

An enzyme is substrate specific because the shape and charge of the substrates are compatible with the active site of the enzyme, where the reaction occurs. This means that an enzyme will not bind to any substrate that its active site does not recognize

A scientist conducted an investigation about the effects of diet on disease resistance in mice and made surprising observations.
Luden [163]

Explanation:

When there is alteration in the DNA sequence in the chromosomes of an organisms which affects the protein expression and therefore the organism involved,the genetic condition is called mutation. its effects can be positive or negative,But,negative effects is most common.

It can be germline in which the genes is affected,or somatic in which the protein expression of the body cell is affected.

Answer:

The fact that the mice with genetic mutation shows similar patterns of inheritance show that some genes in the mice might be playing a dominant role in  diseases resistance in this animals.This is evident since the patterns were peculiar to  mice with mutated ears,and not observed in normal ears.

Therefore the experiment should be carried out again to confirm the influence of these genes on the resistance
