HERE IS AN IMAGE OF RED BLOOD CELLS (ERYTHROCYTES). THEY ALWAYS HAVE A DISTINCTIVE BICONCAVE DISC SHAPE. THE CELLS CONTAIN NEITHER NUCLEI, NOR OTHER ORGANELLES, BUT ARE PACKED WITH HEMOGLOBIN. A.WHAT IS THE FUNCTIONAL ADVANTAGE OF GIVING UP ALL OFTHE STRUCTURES THAT WOULD USUALLY BE FOUND IN A EUKARYOTIC CELL?B. WHAT IS THE ADVANTAGE OF HAVING A BICONCAVE STRUCTURE?

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.
