ollegr [7]

Answer:

This question is incomplete; the complete part is:

Which of the following best explains the reactions of these enzymes?

A) Amylase aids in the removal of a water molecule to break covalent bonds whereas glycogen synthase aids in the addition of a water molecule to form covalent bonds.

B) Amylase aids in the addition of a water molecule to break covalent bonds whereas glycogen synthase aids in the removal of a water molecule to form covalent bonds.

C) Amylase aids in the addition of a water molecule to form covalent bonds whereas glycogen synthase aids in the removal of a water molecule to break covalent bonds.

D) Amylase aids in the removal of a water molecule to form covalent bonds whereas glycogen synthase aids in the addition of a water molecule to break covalent bonds.

The answer is A

Explanation:

In nature, MONOMERS are simpler units that come together to form larger units called POLYMERS. According to this question, Amylase converts carbohydrate polymers to monomers while Glycogen synthase converts carbohydrate monomers to polymers.

Monomers of carbohydrate are joined together by adding water molecule to form covalent bonds between the monomer units, hence, forming a POLYMER. This is how Glycogen synthase catalyzes its reaction of forming carbohydrate polymer (glycogen).

On the other hand, Amylase breaks down large polymer molecules into monomers by removing water molecules in a process called HYDROLYSIS. This breaks the covalent bond that holds the monomeric units together.

Traits controlled by recessive alleles on the X chromosome are more common in males than in females. Explain why. (i dont unders
GaryK [48]
Males have one X chromosome and one Y chromosome whereas females have 2 X chromosomes. Hence females have 2 genes one on each of the X chromosome controlling the respective phenotype(appearance).Males only have one gene on the X chromosome controlling the phenotype because the Y chromosome is not known to control any phenotype linked to the X chromosome. Hence traits controlled by recessive alleles on the X chromosome are more common in males than in females. For a recessive trait to show in a female, she should inherit two X chromosomes that contain the recessive genes.Where as for a male to inherit a recessive trait, he only has to inherit one X chromosome which contains the <span>recessive gene. Hope this helps!</span>
