- BOnly 1 and 3 are incorrect
- C1,2,3 are correct
- DOnly 2 and 4 are incorrect
Correct answer
C. 1,2,3 are correct
Step-by-step solution
Usually carbohydrates are oxidised to release energy, but proteins, fats and even organic acids can be used as respiratory substances in some plants, under certain conditions. During oxidation within a cell, all the energy contained in respiratory substances is not released free into the cell, or in a single step. The energy released by oxidation in respiration is not used directly but is used to synthesise ATP, which is broken down whenever energy needs to be utilised. ATP acts as the energy currency of the cell.
