What do we mean when we say reaction rate? ¿De qué hablamos cuando hablamos de velocidad de reacción? Another word for reaction rate, is the speed of a reaction. Taza de reaccion y velocidad de reaccion se refieren a lo mismo How can we speed up reactions? Como podemos acelerar las reacciones quimicas? Add Enzymes/ Anadiendo Enzimas

How do enzymes work? Como funcionean las enzimas? A + B AB ENZYME AB Enzymes bind to the reactants so the chemical reaction can take place. Las enzimas se unen a los reactivos para que la reacción química puede ocurrir.

How can we speed up a chemical reaction even more? ¿Cómo podemos acelerar una reacción química? Increase enzyme concentration (Aumentando la concentracion de enzima) Increase substrate concentration (Aumentando la concentracion de sustrato)

As substrate or enzime concentration increases, the reaction rate increases & then Remains the same. Cuando la concentración de sustrato o de enzima aumenta, la velocidad de reacción aumenta inicialmente y despues se estabiliza. A + BAB + H 2 O Enzyme

As T increases, enzyme activity increases up to T = ___ and then decreases A medida que la temperatura aumenta, aumenta la actividad enzimática, hasta T = ___ y luego disminuye

What is the optimum temperature for this enzyme? Cual es la temperatura optima de esta enzima?

What is the optimal Temperature for human enzymes? Cual es la temperatura optima de las enzimas humanas?

What is the range at which this enzyme works? A que temperatura funciona una enzima?
