Question

difference between respiration and combustion​

Answer 1

Step-by-step explanation:

Respiration :-

1. It is a slow process.

2. It takes place at the body temperature.

3. It occurs in the living cells.

4. The energy is released in the several stages.

5. It is a biochemical process.

6. ATP or Adenosine Triphosphate is released.

7. Enzymes are required.

8. It occurs in the cell cytoplasm.

Combustion :-

1. It is a fast process.

2. It takes place at high ignition temperature.

3. It is non - cellular.

4. The energy is released that once as heat.

5. It is a physico - chemical process.

6. ATP or Adenosine Triphosphate is not released.

7. Enzymes are not required.

8. It occurs in the mitochondrial matrix.

Answer 2

$\boxed {\green{answer}}$

• Respiration is the phenomena where an organic compound is broken down via oxidation to release energy, CO2 and water. It occurs inside the living cells to obtain energy. Oxygen is needed in the final stage of respiration i.e. in electron transport chain where it gets converted to water. It takes place due to various enzymes.

• Whereas combustion is the burning of any substance at high temperature. It can produce energy in the form of heat and light. It needs oxygen continuously. It does not take place inside living cells. It does not require enzymes.
