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.
First, in glycolysis (glucose becomes pyruvate), 2 ATP are produced by substrate-level phosphorylation. Next, 2 more ATP are created in the citric acid cycle (oxidation of organic molecules, generating #NADH# and #FADH_2#), by substrate-level phosphorylation.
