The rate data from an enzyme catalyzed reaction with and without an inhibitor present is found in the image.
Question: what is the KM and Vm and the nature of inhibition
1. Estimate the concentration of an enzyme within a living cell. Assume that:
(a): fresh tissue is 80% water and all of it is intracellular
(b): the total soluble protein represents 15% of the weight
(c): all the soluble proteins are enzymes
(d): the average molecular weight of the proteins is 150,000
(E): about 100 different enzymes are present

- The following data were recorded for the enzyme catalyzed conversion of S -> P Question: what would the rate be at 5.0 x 10-5 M [S] and the enzyme concentration was doubled? Also, the rate given in the table is from product accumulation after 10 minuets of reaction time. Verify these rates represent a true initial rate (less than 5% turnover). Please helparrow_forwardThe following data was obtained on isocitrate lyase from an algal species. Identify the reaction catalyzed by this enzyme, deduce the KM and Vmax , and determine the nature of the inhibition by oxaloacetate. Please helparrow_forwardIn the table below, there are sketches of four crystals made of positively-charged cations and negatively-charged anions. Rank these crystals in decreasing order of stability (or equivalently increasing order of energy). That is, select "1" below the most stable (lowest energy) crystal.
