Question

Define an enzyme and explain the properties:specificity, affinity and saturation

Answer 1

Enzymes are biological molecules that are produced by the plant or animal or a body itself that use to enhance the activity of the chemical reaction happening in the body.

Mainly enzymes are like catalyser they use to make the speed fast of the reaction and without which the reaction goes very slow.

Like in digestion system they use to break a large molecule into a smaller one for.the body so that they can be digested easily.

"Enzyme speed up the chemical reaction in the body with the help of it active site binding to the substrate in order to form a product.

They use to modify their active site according to the substrate and forms a complex with them called enzyme substrate complex and then they use to provide the specific required product.

One the product is attached they detaches from.the substrate and gets ready for another one.

They use to make the activity faster by binding to substrate.

Enzymes acts on the substrate that can be any molecule for example a carbohydrate on which they will act and break them into small pieces of sugar and glucose.

PROPERTIES OF THE ENZYMES:

SPECIFICITY - This is the property of the enzyme which shows that enzymes are so specific in nature that they use to perform only those work or function for which they are meant for.'

Specific enzyme binds to a specific substrate to perform a specific function.

They are very specific for there work they need specific temperature and ph to work.

They are very specific for their work like lipase is a enzyme for lipid breakdown , protease for the peptide broke down.

AFFINITY - Enzymes are the proteins which have a specific affinity for there substrate they shows the lock key system for the processes.

When active site of enzyme forms a particular shape for the sustrate and shows a great affinty for that binds to it and gives the product.

THE affinity of the enzyme is affected by the concentration of the substrate if there a very high substrate then the afiinity gets decreased.

SATURATION - SATURATION is the property of the enzyme at after which that no further reaction can occur.

It means this is the point at which enzyme goes into the saturation and now no increase in the enzyme activity can occurs whether the susbrate concentration is high.
