There will be no cellular respiration in the respirometer. Reason being all the enzymes and proteins which are known for cellular respiration for the germinating seeds they have denatured fully, after they are being exposed into boiling water.

The peas will be very cooked. If temperature increases, the oxygen will also increase. If the temperature increases further, then the cellular respiration rate in peas decreases because the temperature becomes very high and the peas will be denatured.

The boiled seeds gives zero measurement for the rate of oxygen consumption in the respirometer.

Further Explanation:

The respirometer is an apparatus used to measure the gaseous exchange, specifically the rate of oxygen uptake, providing the indication of the respiratory metabolism activity. Hence by the use of this apparatus we can observe the rate of oxygen uptake in mung beans or any other small living material.

Seeds can be used as the sample for the measurement of gaseous exchange but for the measurement only the living material can be used and if we boil the sample the cells may die and the respiration process gets stopped. Therefore the rate of oxygen consumption will be zero.

During respiration process organism releases carbon dioxide which is absorbed the solution containing potassium hydroxide.

Parts of the respirometer:

1. It consists of one vessel which contains the organism or the sample.

2. Another vessel that acts as the thermobarometer that measures the small changes in temperature or the pressure which causes air in the vessel to either expand or contract.

3. Therefore alteration in the manometer level are due to the activities of respiring sample.
