I think it is D) Both processes involve energy transformations
hope this helps:)
Answer:
Something studied on the molecular level is the water.
Explanation:
Water is a molecule formed by two hydrogen atoms and one oxygen atom, whose chemical representation is H₂O. It is a molecule whose polarity makes it a universal solvent of other polar molecules.
The molecular level corresponds to the level of organization where two or more atoms unite to form molecules or substances, united by chemical bonds. H₂O is studied at this level due to its chemical structure.
With respect to other options:
- <u><em>Hydrogen and oxygen</em></u><em> are atoms, and correspond to the level of atomic organization.</em>
- <u><em>Protons</em></u><em> are particles that are part of an atom, and correspond to the subatomic level.</em>
In the citric acid cycle, the acetyl group of each molecule of acetyl-CoA is converted into two molecule of carbon dioxide and water. It is the pathway that connects carbohydrates ,fat and protein metabolism.
The cycle which carried out by eight enzymes that completely oxidase acetate by which two carbon molecules in the form of acetyl -CoA into two carbon dioxide and water molecules.6- carbon glucose molecule is split into two 3- carbon molecules called pyruvate , which needs in order to create acetyl CoA.
Citric acid cycle is also known as krebs cycle or TCA cycle it is the series of chemical reactions to release to releases stored energy through the oxidation of acetyl-CoA from carbohydrate, fats and protein.
