Question
Describe the influence of temperature on enzyme action.

Answer

Enzymes generally function at a narrow range of temperature. The temperature at which the enzyme shows its maximum activity, is called its optimum temperature. The enzyme activity decreases at temperatures below and above the optimum temperature. At low temperatures, the enzyme is inactive, while at high temperature, the enzyme is denatured and so it loses its activity.

Biology teacher was teaching cell cycle in the class. She taught that cell is the basis from which life exists. Also explained well about cell cycle. Robin who was a bright student was facing difficulties in understanding the topic he reached home and asked her sister who is a student of biology in a college about details of cell cycle and cell theory. She explained him that according to cell theory, cells arise from pre-existing cells and the process involved is cell division. Sexually reproducing organisms start their life from a single cell, called zygote, and cell divisions do not stop with the formation of a mature organism, but continue throughout the life.
