Determine if the statement is true or false, and why. “The key to cell differentiation is that only some of the genes in a cell are expressed at any one time.” A. False, it should read “The key to Protein Synthesis is that only some of the genes in a cell are expressed at any one time.” B. False, it should read “The key to cell differentiation is that only one of the genes in a cell is ever expressed at any one time.” C. True D. False, it should read “The key to cell differentiation is that all of the genes in a cell are expressed at the same time.”

Lactase is essential for digesting lactose in milk. this enzyme is specific for this sugar. why? molecules and active sites vary in size; only properly sized molecules can fit. there is a precise compatibility between the active site and the lactose molecule. specificity refers to the action of the enzyme, such as hydrolysis, and relatively few molecules can be hydrolyzed. reaction-specific enzymes assume a fit by folding around the most numerous substrate molecules.
