Practice question
Question
Measurement of the absorbance of a solution containing NADH in a path length of 1cm cuvette at 340 nm shows the value of 0.31. The molar extinction coefficient of NADH is 6200 M ⁻¹ cm ⁻¹ . The concentration of NADH in the solution is ___ μM (correct to integer number).
Explanation
Understanding enzyme kinetics reveals substrate binding and catalytic efficiency determine reaction rates. Therefore Option NAT is correct because it reflects active-site specificity and regulation, which underpins key processes in biochemistry.
