The answer is 'c<span>hemical energy to mechanical energy'. Within a car engine, a fuel and air mixture is ignited, thereby releasing chemical energy. The fuel air mixture is ignited in a cylinder, and the expanding gasses resulting from the combustion push a moving piston within the cylinder, thereby producing mechanical energy. The piston rotates a crankshaft which ultimately turns the cars wheels through a system of gears.

Answer:
RNA polymerase
Explanation:
The RNA polymerase is an enzyme used in the transcription of genes in DNA to make mRNA. RNA polymerase binds on the promoter region based on the sequences that can be identified by the enzyme’s active site. A mutation can distort the interaction between the promoter region and the enzyme’s active site hence throttle up or inhibit transcription.
Keens cycle connects glycolysis and the citric acid cycle.
