Vedclass · Answer

(B) Plant hormones are chemical substances that regulate plant growth and development. They are synthesized by the plant in very small quantities. Unlike enzymes,which act as catalysts and are not consumed in the reaction,hormones are often expended or metabolized during the physiological processes they regulate. However,in the context of typical biological comparisons,hormones are required in extremely low concentrations compared to many other regulatory molecules,though they differ fundamentally from enzymes because they are not catalytic proteins that remain unchanged after a reaction.

In which of the following respects do plant hormones differ from enzymes?
