Fill in the blanks: 11., the three level of regulation of metabolism is adjusted to,,. The regulation of 12. enzymes involves. There are two ways to regulate the structure of 13. enzymes. 14. enzymes are chemically modified in common ways such as,, and so on. 15., in the chemical modification of enzymes, the modification of enzymes with two forms is achieved by the action of the enzyme. 16. regulates the amount of enzymes by altering enzymes and thus regulating the rate and intensity of metabolism. 17. hormones can be divided into two categories according to the location of the hormone receptor at the site of the cell. 18. the characteristics of glucose, lipid and protein metabolism are enhanced and inhibited during stress.
