Document Summary
Destructive process: anabolism consists of processes that synthesis larger of more complex chemical compounds from smaller chemical building blocks, using energy. Enzymes are protein catalysts that play two main roles: they speed up chemical reactions and regulate them. Most biochemical reactions do not occur on their own. Enzymes represent one of the means by which cells take charge of their own biochemistry. Catalyst is a molecule that accelerates a reaction without being altered itself. Enzymes have substrates and products: the substrates are the initial reactants of the reaction that the enzyme, the products of the enzyme are the compounds produced by the reaction. catalyzes. Names of enzymes usually end in (cid:498)-ase(cid:499) Enzyme- catalyzed reactions exhibit hyperbolic or sigmoid kinetics. For an enzyme molecule to catalyze a reaction, it must combine with a molecule of substrate to form an enzyme-substrate complex.
