Enzymes ______. (choose all that apply)

catalyze chemical reactions
usually allow reactions to move in either direction
bind specific substrates with their active site
some require phosphorylation to energize the enzyme substrate complex

must have complimentary shape and charges to match their substrates at the active site

most chemical reactions in the body would move at a normal rate quickly enough to regulate our cells metabolic without the assistance of enzymes

the same enzyme may be reused multiple times to catalyze conversion of substrates to products

enzymes usually do not work alone; in most cases they function with other enzymes in complex metabolic pathways
