Amount of energy needed for a reaction to proceed

How does competitve inhibitors differ from non-competitive inhibitors?

Competitive inhibitors are the similar shape as the substrate and slow down the rate of reaction similar to non-competitve, however the competitve is reversible but the non competitve is not as it attaches to a different side of the active site but change

What is a coenzyme?

Small, organic, non protein molecule which attaches to the active site for a short period of time. they change as tghe reaction takes place but chnages back unlike products. the role is to carry chemical groups between enzymes so they link together enzyme

What is ethylene glycol poisoning?

Found in antifreeze, not itself poisonous but if taken in to the body it is borken down by an enzyme in the liver called alcohol dehydrogenase. the final product is oxalic acid which is extremely toxic.

What should you drink if you do take in ethylene glycol?

take ethanol as this acts as an inhibitor, slowing the reaction rate by competing for the active site on the alcohol degydrogenase
