(b) Determine how the reaction rate varies with substrate concentration. Rate increases substrate is added when enzyme is saturated with substrate Incorrect Rate decreases additional substrate is added when substrate concentration is low Answer Bank Rate is unchanged additional substrate is added when substrate concentration is very high

If the substrate concentration is twice the KM of an enzyme. The initial velocity (Va) is going to be of the maximum velocity (Vmax) according to Michaelis-Menten (MM) equation, Hint: Use the MM equation to arrive at the answer. O 1/2 O 1/4 O 1/3 O 2/3
Why do most living organisms have an enzyme to decompose hydrogen peroxide? Ideal Gas and Decomposition of Hydrogen Peroxide Quiz Because hydrogen peroxide is present in many foods. Because hydrogen peroxide is toxic and needs to be destroyed. Because hydrogen peroxide does not dissolve in water. Because hydrogen peroxide is produced in the liver.

Protein phosphatase 1 (PP1) helps regulate cell division and is a possible drug target to treat certain types of cancer. The enzyme catalyzes the hydrolysis of a phosphate group from myelin basic protein (MBP). The activity of PP1 was measured in the presence and absence of the inhibitor phosphatidic acid (PA).
