The transition state of an enzyme- catalysed reaction that converts a substrate to a product a) is a transient intermediate formed along the reaction coordinate of the reaction b) has higher free-energy than either the substrates or products c) is the most populated species along the reaction coordinate d) is increased in concentration because the enzyme binds tightly to it e) determines the velocity of the reaction select one: a. a, b, d and e b. a and c c. a only d. d and e e. a, b, c and e

Fugu, also known as puffer fish, is a sushi delicacy that can also be lethal. puffer fish contain a powerful toxin that can kill an adult a few hours after ingestion. sushi chefs who prepare fugu must be specially trained because any contamination of the toxin-free areas of the fish can be deadly. recently this toxin has been put to good use, as scientists have discovered that a purified form of it can treat severe pain in cancer patients. this recent scientific discovery would fall under which area of chemistry? applied biochemistry pure organic chemistry pure physical chemistry applied inorganic chemistry
