enzymes Flashcards
what are enzymes?
large proteins that catalyse reactions
what is the effect of temperature on enzymes? ( as the )
as the temperature increases the rate of reaction increases because enzyme and substrate molecules move around faster and collide more frequenly
at what ph or temperatures can the enzymes active site change?
at extremes of PH or very high temperatures
what is it called when the enzymes cannot catalyse?
the enzyme has been denatured
what are the digestive enzymes?
amylase, proteases, lipases
what are the sites of production for amylase?
salivary glands, pancreas, small intestine
what are the sites of production for proteases
stomach, pancreas, small intestine
what are the sites of production for lipase?
pancreas, small intestine
what is the catalysed reaction for amylase?
starch -> glucose
what is the catalysed reaction for proteases?
proteins -> animo acids
what is the catalysed reaction for lipases?
lipids -> fatty acids and glycerol
what allows the enzymes to adapt to work well in environments with different ph value?
the different optimum ph values
