sB1h enzyme activity

Question 1

describe the effect of temp on enzyme activity

Answer 1

increase temp - activity of the enzyme ( rate of reaction gets faster)
past the optimum - activity of enzymes go rapidly down to 0 because HIGH TEMP - enzymes vibrate - shape of active site changes,substrate doesn’t fit, active site denatured ( no longer catalyse the reaction)

Question 2

effect of substrate concentration on enzyme activity

Answer 2

low substare concentration - free active sites
too much substrate - all active sites filled, no free active sites to increase the rate of reaction

Question 3

effect of pH on enzyme activity

Answer 3

pH more acidic or alkaline - activity down to 0 ( active site denatures )

Question 4

what is optimum pH temp of an enzyme

Answer 4

enzyme fastest possible rate, maximum frequency of collision between enzyme and substrate
