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.

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.
Substrate-level phosphorylation is a type of chemical re action that results in the formation of adenosine triphosphate (ATP) by the direct trans fer of a phosphate group to adenosine diphosphate (ADP) from a reactive intermediate. substrate. Molecule that undergoes a change in a re action catalyzed by an enzyme.) ~ s bind to the active site of an enzyme and convert the ~ s into products. 5) The three dimensional shape of the enzyme and of the active site determines its activity. 6) The way in which a ~ fits into an active site is often referred to as the lock and key model.
