    different pH solutions as well as to measure the absorbance of catecholase in solutions with different concentrations of potato juice and phosphate buffers. Absorbance of the enzyme catecholase was at an optimum level when pH was close to neutral. When pH was acidic or basic‚ the catecholase was less effective. Also‚ when there was a higher concentration of potato juice and a lower concentration of phosphate buffer‚ absorbance of the enzyme increased. Introduction According to Edmund J. Stellwag
