The Effect of pH on a Food Preservative September 18‚ 2012 Objective: To study the affect of pH on a food preservative. Chemical Equation: C6H5COONa + HCL ------ C6H5COOH + NaCl Procedure: This experiment was started with a clear solution of sodium benzoate and HCl was added to it‚ ultimately producing benzoic acid. First‚ .3395 g of sodium benzoate was weighed‚ then it was dissolved in water‚ causing it to disassociate into ions. Next‚ 3M of HCl were added drop wise to the solution

What is the biological significance of having two different types of terminators in transcription? Transcription in prokaryotes is terminated by factors called rho-dependent and rho-independent terminators; Rho is a ring-shaped protein and is the main factor required for termination (Leland‚ 2010). The rho-dependent and rho-independent terminators play a major role in the separation of an RNA transcript from the DNA template which signifies the end of transcription. However‚ the exact process is

studying the effect of pH on catalase activity. Catalase by scavenging hydrogen peroxide to water and oxygen is an important enzyme of cell defense mechanisms against oxidative stress in all living organisms (Dat et al.‚ 2003). Cells use catalase because it is the most efficient enzyme as an antioxidative enzyme which lowers hydrogen peroxide or superoxide to accumulate to toxic levels in plant growth (Bowler et al. 1992). The formula that involves catalase as the enzyme is . pH is a measure of the
