Introduction:
Every enzyme present in the cell catalyzes the reactions of the cell. There is a non protein part that is associated with the enzyme, which is called a cofactor or prosthetic group. These cofactors are responsible for the proper functioning of the enzymes. Enzyme cannot perform in the absence of cofactors.
To determine: Similar reactions of citric acid cycle with the conversion of isocitrate into α- ketoglutarate.
Introduction:
Conversion of isocitrate into α- ketoglutarate is a decarboxylation process and it occurs in the presence of the enzyme isocitrate dehydrogenase. This enzyme reduces isocitrate to yield α- ketoglutarate. This reaction is the third step of the citric acid cycle, the similar reactions may take place in the whole cycle.

- The following data were recorded for the enzyme catalyzed conversion of S -> P. Question: Estimate the Vmax and Km. What would be the rate at 2.5 and 5.0 x 10-5 M [S] ?arrow_forwardPlease helparrow_forwardThe 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_forward
- The 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. Select "2" below the next most stable (next lowest energy) crystal, and so forth. A B 鹽 (Choose one) +2 C +2 +2 (Choose one) D 鹽雞 (Choose one) (Choose one)arrow_forward1.
