AnswerClick to flip back
A
all of these
💡 Explanation:
- in certain conditions such as starvation when sufficient amount of glucose is not present in the blood the foremost priority of the body is to provide brain with the sufficient amount of glucose.
- So for the other body parts the energy that is to be provided can be done by the use of other substrates instead of glucose.
- First alternative of glucose is fatty acid which is stored in the body. These fatty acid molecules are converted to acetyl coA by the process of beta oxidation and used in the kerbs cycle to provide the cell with energy.
- Glycerol is also a fatty acid which is used as the other fatty acid in the kerbs cycle.
- Amino acids are the part of protein molecules which are usually not stored in the body but can be used in the kerbs cycle whenever they are provided to the cell.
- Therefore the answer 'all of these' is correct.
