Mexican redbud (Cercis canadensis ssp. Mexicana) trees have a rounded and dense form that is broad and compact. The stems on Mexican redbuds are thicker than other redbud species, as well as more rigid. They grow 15 to 25 feet tall and have pink to purple spring-blooming flowers. The dark-green, leather-like leaves on Mexican redbud trees grow 2 to 6 inches long and have a glossy appearance as the tree ages.
enzymeâsubstrate complex. A Dictionary of Biology. Â© A Dictionary of Biology 2004, originally published by Oxford University Press 2004. enzymeâsubstrate complex The intermediate formed when a substrate molecule interacts with the active site of an enzyme. Following the formation of an enzymeâsubstrate complex, the substrate molecule undergoes a chemical reaction and is converted into a new product.
In chemistry, a substrate is typically the chemical species being observed in a chemical reaction, which is organic in nature and reacts with a reagent to generate a product. In synthetic and organic chemistry, the substrate is the chemical of interest that is being modified. In biochemistry, an enzyme substrate is the material upon which an enzyme acts. When referring to Le Chatelier's principle, the substrate is the reagent whose concentration is changed.
