Addition polymerisation???
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>
Answer:
C) Most of the free energy available from the oxidation of glucose remains in pyruvate
Explanation:
The free energy for the oxidation of glucose to CO2
and water is -686kcal/mole and the free energy for the reduction of
NAD+ to NADH is+53 kcal/mole. Why are only two molecules of NADH
formed during glycolysis when it appears that as many as a dozen
could be formed and most of the free energy available from the oxidation of glucose remains in pyruvate
Answer:
Oil can be burned to heat water, using the steam to generate power. Or, oil can be burned under pressure to produce exhaust gasses.
