ATP is hydrolyzed into ADP in the following reaction: ATP+H 2 OâADP+P i +free energy. Like most chemical reactions, the hydrolysis of ATP to ADP is reversible. The reverse reaction combines ADP + P i to regenerate ATP from ADP. Since ATP hydrolysis releases energy, ATP synthesis must require an input of free energy. ADP is combined with a phosphate to form ATP in the following reaction: ADP+P i +free energyâATP+H 2 O. ATP and Energy Coupling
Getting Started. Fouled, damaged, or worn out spark plugs can lead to a variety of engine problems, such as misfires, hard starts, increased emissions, and poor fuel economy. For most vehicles, you should replace your spark plugs every 30,000 miles (consult your owner's manual for your specific interval).
Spark plugs are responsible for igniting the fuel that your engine uses to run. When you turn your key, a small voltage of power is sent to the ignition coil, where it is transformed into high voltage currency. This high voltage currency is sent through the ignition cables to the spark plugs.he number of spark plugs in the car is the same as the number of cylinders, although some vehicle manufacturers will use two spark plugs per cylinder. Over time, the spark plugs wear out and require replacement.
