Which conversion is controlled by insulin?

The conversion of glucose to glycogen is activated and controlled by insulin. Conversion of glucose to glycogen is called glycogenesis.

Glycogen is the principal form in which glucose is stored. The storage is done in the liver and also in muscle cells.

Glycogenesis is stimulated by the hormone insulin and takes place when blood sugar levels are sufficiently high to allow excess glucose to be stored in the liver and muscle cells.

Insulin facilitates the uptake of  glucose into muscle cells though it is not  required for the transport of glucose into liver cells. However insulin has a profound effect on glucose metabolism  in liver cells stimulating glycogenesis and inhibiting glycogenolysis, the breakdown of glycogen to glucose. 

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.

hi~~

i would say that hybridization occurs frequently in nature, because there are many types of hybrids that have occurred naturally, such as the mule (male donkey + female horse)
