A TCD is any sign, signal or marking that involves traffic. A speed limit sign is a type of TCD. A TCD ticket is a lesser violation carrying only 2 points. Even the lowest level speeding violation carries 3 points and the stigma of a speeding violation.
Beta oxidation of both Fatty acids produces both FADH2 and NADH. How many ATP can be made by oxidative phosphorylation from the FADH2 and NADH produced by one turn of the Fatty acid spiral? Answer: 5, Don't have a clue why.
Coupled reactions are also used to generate ATP by phosphorylating ADP. The nonspontaneous reaction of joining ADP to inorganic phosphate to make ATP (Equation 8, below and Figure 2, above) is coupled to the oxidation reaction of NADH or FADH2 (Equation 9, below).
