Active Site - Attachment of substrate Often a water-free cavity Pouch-like Substrate - Substance acted upon enzyme Also called as chemical reactant Allosteric Site - Another cavity, other molecule other than substrate (inhibitors) May bind regulator molecules and,thereby. Be significant to th...

An enzyme maybe defined as a: - Biological catalysts The Michaelis-Menten Constant in the rate of conversion of substrate to product is determined by: - Substrate concentration and rate of dissociation of enzyme-substrate complex Isoenzyme - The electrophoretic property is different for each isoe...

Physiology - - The study of function Homeostasis - - maintenance of the same state - maintaining order - requires energy and a means to utilized the energy Glucose Fatty Acids Amino Acids Volatile Fatty Acids Ketone - - Sources of energy

Catalyst - 1. Chemical or biological substance or structure that lowers activation energy 2. Accelerates the rate of a chemical rxn Enzymes - Biological catalysts that are capable of performing multiple rxns (are recycled). They can be proteins or RNA, are faster than chemical catalysts, and act ...

Which of these statements is correct? A) A catalyst decreases the activation barrier by different amounts for the forward and reverse reactions. B) A catalyst decreases the activation barrier by the same amount for both the forward and reverse reactions. C) A catalyst increases the activation b...

enzymes increase reactions by lowering the activation energy-which is the energy needed to go from the reactant to the transition state. The transition state is called the enzyme substrate complex - function of enzymes Classes of enzymes: oxidoreductase-oxidation/reduction reactions, transferase-...
