Consider an enzyme catalysed reaction treated with inhibitor. Enzyme kinetic was analysed with Eadie Hofstee equation. A plot of V0 versus V0/[S] for an enzyme-catalyzed reaction is shown below. The control curve was obtained in the absence of inhibitor. Which effect is shown on the enzyme activity when an inhibitor is added to the reaction mixture?

#Unit 5. Developmental Biology
Normally, the FgfR3 protein (a receptor tyrosine kinase) is activated by a fibroblast growth factor and signals the chondrocytes to stop dividing and begin differentiating into cartilage. This signal is mediated by the Stat protein, which is phosphorylated by activated FgfR3 and then translocated into the nucleus. Inside the nucleus, Stat activates the genes encoding a cell cycle inhibitor, the p21 protein. The mutation in FgfR3 causes the lethal condition thanatophoric dysplasia. This condition may be achieved by:
A. Mutations in the extracellular domain of the FgfR3 protein
B. Mutations in the tyrosine kinase intracellular domain of the FgfR3 protein
C. Mutations in the transmembrane domain of the FgfR3 protein

Following are some facts regarding C3 and C4 Plants
a.) In C4 plants the reduction is caused by the additional energy requirements such as 1 ATP per CO2 from C3 plants
b.) C4 leaves are exposed to low O2 concentrations, the quantum yields for CO2 fixation remain constant while C3 leaves are exposed to low O2 concentrations quantum yield increases
c.) C3 leaves are exposed to low O2 concentrations, photorespiration is maximized
d.) Plant with the C4 metabolism need more rubisco than C3 plants to achieve a given rate of Photosynthesis
