Question

Along with the heat; sound & light are also produced during burning of fuel. Similarly, whether the sound & light are produced during oxidation of nutrients in cell?

Answer 1

No inside a cell only light energy is changed into chemical. no sound is produced

Answer 2

The reactions where heat is produced along with other products is known as an exothermic reaction. When a fuel is burnt heat,sound and light are produced.

When food is oxidized by our body(respiration) then heat,light and sound are produced along with energy.


So,both the reactions are similar in a way that both of them are exothermic reaction.


Hope Helps.
