Dissimilatory sulfate reducing bacteria utilizes:

Of the six curves labeled in the Lineweaver-Burk graph below, three represent the effects of 0 mM, 5 mM, and 15 mM of a competitive inhibitor on a hypothetical enzyme.

Which of the curves most likely represents the 5-mM concentration of the competitive inhibitor?

Chilarity of DNA is due to -

The V_max of a reaction is 2.5 and turnover of the reaction is 50. What is the total enzyme concentration of the reaction?

The rate of the reaction can be expressed in terms of rate of appearance of product and disappearance of reactant and are expressed as

Rate= -∆ [A]/ ∆t =-∆ [B]/ ∆t= ∆ [P]/ ∆t

What does the negative signs with A and B represents
