The Reedy River put Greenville on the mapâand, like its meandering currents and rushing falls, is the centerpiece for its rise, fall, and triumphant rise again. It has humble beginnings. Greenvilleâs Reedy River starts with a few springs seeping out of the ground just north in Travelers Rest off Ebenezer Church Road. It gathers strength, breadth, and force as it flowsâtouching thousands of lives by the time it reaches its most prominent feature in the heart of the city.
Role of enzymes in metabolism. Some enzymes help to break down large nutrient molecules, such as proteins, fats, and carbohydrates, into smaller molecules. This process occurs during the digestion of foodstuffs in the stomach and intestines of animals. Other enzymes guide the smaller, broken-down molecules through the intestinal wall into the bloodstream.
Enzymes /ËÉnzaÉªmz/ are macromolecular biological catalysts. Enzymes accelerate, or catalyze, chemical reactions. The molecules at the beginning of the process upon which enzymes may act are called substrates and the enzyme converts these into different molecules, called products. Almost all metabolic processes in the cell need enzymes in order to occur at rates fast enough to sustain life. The set of enzymes made in a cell determines which metabolic pathways occur in that cell. The study of enzymes is called enzymology. Enzymes are known to catalyze more than 5,000 biochemical reaction types.
