The metabolic rate can be measured in different ways: As a general rule, the greater the mass of an organism the higher that organism’s metabolic rate is. Organisms with high metabolic rates ...

Mar 2, 2024 · Michaelis-Menten Kinetics. Two 20 th century scientists, Leonor Michaelis and Maud Leonora Menten, proposed the model known as Michaelis-Menten Kinetics to account for enzymatic dynamics. The model serves to explain how an enzyme can cause kinetic rate enhancement of a reaction and explains how reaction rates depends on the concentration of ...
Definition. Reaction rate is the speed at which a chemical reaction occurs, typically measured by the change in concentration of reactants or products over time. This concept is crucial in understanding enzyme kinetics and how enzymes influence the speed of biochemical reactions, particularly through models like Michaelis-Menten, which ...
Measuring metabolic rate. The sum of all metabolic reactions in the body can be measured as a function of oxygen consumption, carbon dioxide production and heat production. Oxygen is needed in aerobic respiration, carbon dioxide is a byproduct of respiration, while heat is lost energy by many reactions. The higher these variables, the higher ...
