Question

During aerobic respiration, energy is released in a stepwise manner and ATP formation takes place with the help of this energy. What will happen if this energy is released at a single step instead of in parts?

• A. Incomplete oxidation of glucose take place
• B. All the amount of energy can be utilized by the cell as more ATP molecules are produced
• C. Maximum amount of this energy is wasted in the form of heat and cell may die
• D. Cell will follow anaerobic path of respiration

Answer 1

The correct option is C Maximum amount of this energy is wasted in the form of heat and cell may die

Aerobic respiration proceeds in a series of steps, which also increases efficiency - since glucose is broken down gradually and ATP is produced as needed, less energy is wasted as heat. If this energy is released at a single step maimum amount of energy will be wasted in the form of heat.
