Question

The enzymes act between the temperature range of
(a) 35 degrees - 40 degrees
(b) 30 degrees - 35 degrees
(c) 40 degrees - 45 degrees
(d) 50 degrees and above

Answer 1

Hint Enzymes are proteins which act as catalysts which help in accelerating biological as well as chemical reactions and it is also called as substrates which convert substrates into different molecules known as products.

Complete answer
- Enzymes are biological catalysts which accelerate chemical reactions in organisms. Optimum temperature is the temperature at when there is maximum enzyme activity. In humans, this temperature is 37.5 degree Celsius, which is the same as the normal body temperature. A rise in temperature above 40 degree Celsius results in denaturation of the proteins of enzyme.This option is correct.

Additional information In digestive systems enzymes break down larger complex molecules into smaller molecules for eg-Glucose for helping the body to use as a fuel.
Liver enzymes work to breakdown toxins in the body for that it uses a range of enzymes.
In DNA replication enzymes help in the process by unwinding the DNA coils and copying the information.
So, the correct answer is, ‘(a) 35 degrees - 40 degrees’.

Note Enzymes are found in our body. Enzymes are used for a proper digestive system. Digestive enzymes are produced in the pancreas, stomach and small intestine. There are 3 main types of digestive enzymes
- Amylase breaks down starch and carbohydrates into sugars.
- Protease breaks down proteins into amino acids.
- Lipase breaks down lipids, which are fats and oils, into glycerol and fatty acids.
