What is the catalyst in a metabolic pathway?

A catalyst in a metabolic pathway is typically an enzyme that speeds up the rate of a specific chemical reaction without being consumed in the process. Enzymes achieve this by lowering the activation energy required for the reaction to occur, allowing metabolic processes to proceed efficiently within the cell.

-55mV


What describes a catalyst?

A character who makes events happen.


What is one way to overcome activation energy and why does it work?

One way to overcome activation energy is by increasing the temperature of the reactants. This works because higher temperatures provide the molecules with more kinetic energy, leading to more frequent and forceful collisions. As a result, a greater proportion of molecules can achieve the energy required to surpass the activation energy barrier, facilitating the reaction.


Which substance can affect the rate of a chemical reaction without itself being changed or used up during the reaction?

The answer you're looking for is a "catalyst". Unless you are in Chemistry 12, you don't need to know that reaction equations with more than 3 molecules on the reactants' side consist of several steps, in which intermediates (things that are produced/used and involved in the reaction, but are reused or produced before the end) like catalysts come into the reaction. Catalysts influence reaction rate, but do not show up in the final equation of an overall reaction. They are sometimes listed over the "arrow" in the equation. Inhibitors slow reactions, and are the opposite of catalysts in that way. Source - Chem 12 Student under Jim Nattrass

How can I mix the Liquid Rubber to repair the roof leaks?

To mix Liquid Rubber for repairing roof leaks, follow the manufacturer's instructions for the specific product you're using. Typically, you'll need to combine the Liquid Rubber with an appropriate hardener or catalyst if required. Use a clean container and a mixing tool to thoroughly blend the components until you achieve a uniform consistency. Apply the mixture promptly to the affected area using a brush, roller, or spray, ensuring good coverage for effective sealing.
