Which of the following functions are performed by enzymes? fighting disease creating movement regulating cell processes sending chemical messages
Weegy: Enzymes function as organic catalysts. [ A catalyst is a chemical involved in, but not changed by, a chemical reaction Enzymes allow many chemical reactions to occur within the homeostasis constraints of a living system. enzymes also increase the rates of chemical reactions by at least a millionfold so i would say processes sending chemical messages ] (More)

Enzymes are used during chemical reactions that take place within the body. What do enzymes change to affect the chemical reactions that take place in living cells? a. The products of the reaction. c. The temperature of the reaction. b. The speed of the reaction. d. The pH of the reaction.
Weegy: d. The pH of the reaction. Enzymes are shaped proteins, normally produced by organisms to catalyse chemical reactions. [ They function in a similar way to chemical catalysts, by lowering (or occasionally raising) the 'activation energy' for a specific reaction, and are not used as a reactant. oweing to the nature of enzymes, as proteins, they function optimally at a set temperature and pH, as their presence outside these conditions is often to the detriment of the protein structure, or instead, in the case of low temperatures, slows the reaction and frequently fails to meet the activation energy. Enzymes will usually speed up a chemical reaction, and will additionally facilitate it when it would otherwise not occur. ] User: The elements or compounds produced by a chemical reaction are known as reactants. true or false (More)
