The correct Answer is:
To solve the question regarding the energy released per gram from different respiratory substrates (wheat starch, potato starch, and dry starch), we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Substrates**: The question mentions three substrates: wheat starch, potato starch, and dry starch. All of these are rich in carbohydrates, specifically starch. 2. **Understand Energy Release**: The energy released per gram from a respiratory substrate is referred to as its physiological value. This value indicates how much energy can be obtained from a specific substrate when it is metabolized. 3. **Determine the Physiological Value of Starch**: The physiological value of starch is approximately 4.0 kilocalories per gram. This value is consistent across different types of starch, as they all provide similar energy when metabolized. 4. **Compare the Energy Release**: Since all three substrates (wheat, potato, and dry starch) are primarily composed of starch, they will all yield the same amount of energy per gram when used as a respiratory substrate. 5. **Conclusion**: Based on the above points, the energy released per gram is the same for all three substrates. Therefore, the correct answer to the question is that the energy released per gram is the same in all cases. ### Final Answer: The energy released per gram would be the same in all cases. ---
