Los gatos gordos se pueden producir por dos genes independientes. El genotipo "oo" genera un gato gordo y estéril, llamado obeso; su alelo dominante "O" da lugar a crecimiento normal. El genotipo recesivo "aa" también produce un gato gordo y estéril llamado adiposo, mientras que su alelo dominante ocasiona crecimiento normal. ¿Qué proporciones fenotípicas de gatos gordos frente a normales podemos esperar en F1, siendo los padres de genotipo OoAa?

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.

i think this picture will you.
