enzymes
enzymes are protein which speedup chemical reaction inside living organism by minimizing the activation energy,they are biological catalysts.
function enzymes
the most important function of enzymes is to help in digestion ,the process of turning the food we eat energy for e.g enzymes in our saliva intestines stomach and pancrease the brake down protein carbo hydrate in fact enzymes also halp in breathing ,nerve function muscle building
the most comman digestive enzyme are carbohydrate, lipase and protein
Mechanism of Enzyme Action
Lock and key model
Ind used fit model
Lock and key model
in 1994,German chemist email fisher give lock and key model to describe lock and key model to describe mechanisms of enzyme action
according to this model as a specific key open a specific lock like wise a specific attached with specific substrate
Induced fit model
in 1958,american biologist Danial koshland propose induce fit model to modify lock and key model
according to this shape of enzymes not fixed enzymes change its according to the shape of given l available substrata
specificity of enzyme
about 2000 enzymes are know today
enzyme are very specific t words their substrate
proteases only break down proteins
lipase only brake down lipids
amylase only brect
