Amino acids serine, aspartic acid and phenylalanine are present on the active site of an enzyme. Explain which forces may be involved in binding the drug to the enzyme if the drug inhibits the holding of substrate on the active site of enzyme .

Which forces are involved in holding the drugs to the active site of enzymes ?

Explain the role of allosteric site in enzyme inhibition?

Drugs which bind to the receptor site and inhibit its natural function, are called

Which of the following minerals activate the enzymes involved in respiration?

Make a chart (with diagrammatic representation) showing a restriction enzyme, the substrate DNA on which it acts, the site at which it cuts DNA and the product it produces.

Fill in the blanks: The activity of enzyme inhibtied when modualtors bind to it is known as .......................... inhibition.

Enzymes are proteins. These are long chains of amino acids linked to each other by peptide bonds. Amino acids have many functional groups in their structure. These functional groups are many of them at least, ionisable. As they are weak acids and bases in chemical nature, this ionization is influenced by pH of the solution. For many enzymes, activity is influenced by surrounding pH. This is depicted in the curve below: explain briefly.

Activation energy for the acid catalysed hydrolysis of sucrose is 6.22 kJ mol^-1 , while the activation energy is only 2.15 kJ mol^-1 when hydrolysis is catalysed by the enzyme sucrase. Explain.
