Feb 2, 2015 · 3 Answers. All electrochemistry is relative. And any time you have a reduction or oxidation reaction, you are dealing with an electrochemistry problem. NADH is "more energetic" than NAD+ because the hidden assumption is that energy levels are relative to reaction with the atmosphere. NADH can react with oxygen in the atmosphere to release energy.

Rotational Energies The classical energy of a freely rotating molecule can be expressed as rotational kinetic energy. where x, y, and z are the principal axes of rotation and I x represents the moment of inertia about the x-axis, etc. In terms of the angular momenta about the principal axes, the expression becomes.

Both of these coenzymes play crucial roles in this. Each molecule of NAD + (or NADP +) can acquire two electrons; that is, be reduced by two electrons. However, only one proton accompanies the reduction. The other proton produced as two hydrogen atoms are removed from the molecule being oxidized is liberated into the surrounding medium.Larger molecules feature internal rotations, where a group of atoms rotates with respect to the rest of the molecule. In general, internal rotations are torsions about rotatable bonds, which are often not freely rotatable. ... is the moment of inertia with the reduced mass \(\mu\) and \[B = \frac{h}{8 \pi^2 I c}\] is the rotational constant.The eight steps of the cycle are a series of chemical reactions that produces two carbon dioxide molecules, one ATP molecule (or an equivalent), and reduced forms (NADH and FADH 2) of NAD + and FAD +, important coenzymes in the cell.
