Generally which factor regulates the enzyme activity. (a) Light (b) Temperature (c) Water (d) Humidity
Answers
"(b) Temperature regulates the enzyme activity.
Enzymes are basically a protein molecule that takes the role of biological catalysts. The enzyme activity is affected by the following factors:
(a) Enzyme concentration: With increase in the enzyme concentration, the activity linearly increases.
(b) Substrate concentration: The enzyme activity increases with increase in substrate concentration and saturates, for a little quantity of enzyme. This saturation point is called the limiting rate beyond which there is no increase in enzyme activity.(c) Temperature: Enzyme activity is maxi mum within an optimal temperature range. Sub-optimal ranges have low activity as the chains in the enzymes are restricted in movement. Under other conditions, temperature beyond the optimal range also leads to low activity as the protein denatures.(d) PH: Enzyme activity peaks for every enzyme within its optimal pH range. (e) Activators: Certain enzymes show maximum activity under specific metallic cautions such as Mg2+, Ca2+ etc.
