The two types of enzymes are apoenzymes and holoenzymes on the basis of their activity state.

Enzymes are the proteinaceous molecules that speed up the biochemical reaction taking place inside living systems.

Apoenzymes are the catalytically inactive form of the enzyme that is present in the cells when the enzyme is not required. It activates upon the binding of a cofactor. Apoenzymes are not capable of catalyzing a reaction. It is considered an incomplete enzyme.

Holoenzymes are the active form of enzymes. When the enzyme binds to the cofactor, it is the catalytically active form known as the holoenzyme. It is considered the complete enzyme.

Apoenzymes form when the cofactor or coenzyme is removed from the active site of the enzyme and only the protein component is left alone, it is catalytically inactive.

The cells of the macula densa and the juxtaglomerular cells form the

allsm [11]

Answer:

The preferable option will be - B.

B. juxtaglomerular complex.

Explanation:

The cells of the macula densa, the juxtaglomerular cells, and the extraglomerular mesangial cells together form <u>the juxtaglomerular complex or juxtaglomerular apparatus. </u>

The given options were -

a. nephron loop (loop of Henle).

b. juxtaglomerular complex.

c. renal corpuscle.

d. filtration membrane.

e. afferent arteriole.

The juxtaglomerular apparatus regulates the blood pressure and also regulates the filtration rate of the glomerulus.

In a particular family, one parent has Type A blood, the other has Type B. They have four children. One has Type A, one has Type

AlladinOne [14]

Answer:

The correct answer is -

Parental genotypes: AO & BO

Children genotypes: AB, AO, BO, and OO

Explanation:

In the human blood group system, more than two types of alleles are present that lead to the existence of four blood groups in the human population.

Here, A and B alleles are co-dominant while the O allele is recessive to both A and B alleles in the ABO system.

The cross depicting the genotypes of children is

IA IO

IB IAIB IBIO

IO IAIO IOIO

In this cross, we get the same result as given in the question -

One parent has A and the other has B type blood while the children have all four types of blood groups One has Type A, one has Type B, one has Type AB, and the last has Type O. It is possible only when parents are heterozygous in their genotypes and not expressing codominance.
