Joel Toomer Chemical reactions take place at different speeds. Chemical reactions which have high rates of reaction, are very quick, meaning that a shorter period of time lapses between the start and finish of the experiment. These experiments are often very volatile as a greater change is happening...

Photosynthesis is the process used to trap light energy and convert it to chemical bond energy, forming organic compounds. Photosynthesis is divided into two groups: the light reactions and the dark reactions. The light reactions produce ATP, NADPH and oxygen. The dark reactions use this energy to c...
