Answer:
a. True.
Explanation:
Even though the cells in our body rely on glucose as a source of energy, they can replace glucose's energy with lipids or proteins' energy. In the brain's case, this is not possible since the blood-brain barrier, which is a highly selective barrier between the blood and the extracellular fluid in the central nervous system, allows the passage of glucose as the only source of energy. This is why maintaining the correct levels of glucose is crucial for the metabolism in the brain.

The molecule shown below is a molecule that is generally termed as the energy currency molecule of the cell, and that is ATP.
The components of it include:
1. Adenine nitrogenous base, the far left
2.Ribose, sugar the same sugar found in RNA molecules, middle.
3. Triphosphate - 3 covalently bound phosphate groups ready to split apart as they don't typically like being bonded in that manner, due to charges on phosphate, being negatively charged.
Deoxyribose+phosphate group+polymerase can be found in DNA molecule.
