Question

for cellular respiration lab we had germinated peas and then we had germinated peas that we boiled for five minutes. when you boil the peas do they become non-germinated? is CO2 produced in both germinating and non germinating peas?

Answer 1

Cellular respiration is the process of breakdown of Sugars to produce carbon dioxide and water and ATP. ATP is the energy currency of the cell which is used by the cell for its growth and metabolic activities.

Cellular respiration is enzymatic process. We know that all the enzymes work at a specific pH and temperature which is called as optimum pH and optimum temperature. Any deviation from the optimum value is detrimental to the catalytic power of enzyme.

In the given question we have boiled some of the seeds. So after boiling, all the enzymes would have been denatured. This will result in the inability of enzyme catalysed cellular respiration and therefore there will be no production of carbon dioxide in germinating seeds.

But the test tube which are not boiled, cellular respiration will take place on carbon dioxide will also be produced.

Carbon dioxide is produced during cellular respiration. During germination, the plant needs ATP for seed germination and in non germinating seeds, the plant need ATP for its growth. So cellular respiration and therefore carbon dioxide will be produced in both the cases.
