The Krebs cycle charges only ADP, but the energy contained in ATP can be transferred to one of the other nucleosides by means of an enzyme called nucleoside diphosphate kinase. This enzyme transfers the phosphate from a nucleoside triphosphate, commonly ATP, to a nucleoside diphosphate such as guanosine diphosphate (GDP) to form guanosine triphosphate (GTP).
Bigger jets allow more fuel and smaller jets allow less. The rejetting process figures out which size jets is needed to keep an engine running with the right mixture. Too little fuel and the engine may starve or overheat at high RPMs.Too much fuel and the engine could flood and bog out.hares & Saves. Save. Replacing an exhaust with a carburetor-type engine is more than just bolting on a new pipe. Whether itâs a car or motorcycle or scooter, you are likely going to need to make sure your carburetor is running with the correct jetting for the new exhaust.
Similarly, rapid cooling of the catalytic converter, such as by being submerged in water, can cause the internal honeycomb structure to break apart and obstruct the exit to the exhaust pipe. If the catalytic converter becomes plugged, engine efficiency will decrease noticeably. If you are at all concerned about the performance of your catalytic converter, call into your nearest Kwik Fit for a free exhaust check.
