According to some newer sources, the ATP yield during aerobic respiration is not 36–38, but only about 30–32 ATP molecules / 1 molecule of glucose [12], because: ATP : NADH+H + and ATP : FADH 2 ratios during the oxidative phosphorylation appear to be not 3 and 2, but 2.5 and 1.5 respectively.
Carnitine O-acetyltransferase also called carnitine acetyltransferase (CRAT, or CAT) [5] (EC 2.3.1.7) is an enzyme that encoded by the CRAT gene that catalyzes the chemical reaction acetyl-CoA + carnitine ⇌ {\displaystyle \rightleftharpoons } CoA + acetylcarnitine
This is usually to accumulate high concentrations of molecules that a cell needs, such as glucose or amino acids. If the process uses chemical energy, such as adenosine triphosphate (ATP), it is called primary active transport. Membrane transport proteins that are driven directly by the hydrolysis of ATP are referred to as ATPase pumps. [10]

The illustration is, for diagrammatic purposes, of a 12 carbon fatty acid. Most fatty acids in human plasma are 16 or 18 carbon atoms long. A diagrammatic illustration of the transfer of an acyl-CoA molecule across the inner membrane of the mitochondrion by carnitine-acyl-CoA transferase (CAT). The illustrated acyl chain is, for diagrammatic ...
At cytoplasmic conditions, where the ADP/ATP ratio is 10 orders of magnitude from equilibrium, the ΔG is around −57 kJ/mol. [12] Along with pH, the free energy change of ATP hydrolysis is also associated with Mg 2+ concentration, from ΔG°' = −35.7 kJ/mol at a Mg 2+ concentration of zero, to ΔG°' = −31 kJ/mol at [Mg 2+ ] = 5 mM.

ATP synthase, also called complex V, is the final enzyme in the oxidative phosphorylation pathway. This enzyme is found in all forms of life and functions in the same way in both prokaryotes and eukaryotes. [67] The enzyme uses the energy stored in a proton gradient across a membrane to drive the synthesis of ATP from ADP and phosphate (P i).
