3 reactions we performed: Reaction 1: Excess PFK1 Vmax=1625uMol/min (w/ excess pfk1) [S] or Lab determined substrate conc. = 0.3mM Km determined through literature = 20mM v=(1625uMol/min)*(4.6mM)/(20mM)+(4.6mM) v=303.861789 uMol/min Reaction 2(control): No PFK1 Reaction 1: Excess PFK1 Vmax=0uMol/min (w/ excess pfk1) [S] or Lab determined substrate conc. = 0mM Km determined through literature = 0mM v=(0uMol/min)*(0mM)/(20mM)+(0mM) v=0 uMol/min Reaction 3: Less PFK1 Vmax=100Mol/min (w/ excess pfk1) [S] or Lab determined substrate conc. = 1.25mM Km determined through literature = 20mM v=(100uMol/min)*(3.5mM)/(75mM)+(3.5mM) v=41.1764706 uMol/min 303.86/41.1765= 7.37945187 times increase with the presence of excess PFK1. Time for biofilm formation overall: 24-48 hours for visible EPS Average thickness=20uM Average length= 80uM Average height=5uM Volume=l*w*h 20*80*5= 8000uM3 36 hours in mins= 2160 min 8000/2160 volume/ time= umol/min 3.7037037 uMol/min This shows that the rate of reaction for the formation of biofilm is less than the rate of reaction for the catalyzed PFK1 reaction indicating that the degradation done by the enzyme will be greater than the rate of formation allowing for the biofilm to be degraded instead of just formed at a lower rate
