What are the characteristics of enzymes? |
|
Answer» Enzymes-characteristics: (i) Approximately all the enzymes are proteinaceous in nature. An enzyme/protein has a primary structure (amino acid sequence of protein). Enzyme like protein has secondary and the tertiary structure. (ii) The backbone of protein chain folds upon itself, chain criss-crosses itself and so several crevices or pockets are made out. One pocket is known as ‘active site'. So the enzymes, through their active site, catalyse reactions at a high rate. (iii) The enzymes get denatured at a high temperatures (above 40°C). The enzymes isolated from organisms who live under extremely high temperatures e.g., hot vents and sulphur springs, are stable and retain their catalytic power at high temperatures (upto 80°-90°C). |
