Animation showing the catalytic mechanism in the Haber process that produces ammonia (NH3) from nitrogen (N2) and hydrogen (H2) gas. The catalyst used is a metal, usually iron. The animation shows a molecule of nitrogen (dark blue) attaching to …

Sometimes, scientists need to make a reaction happen faster. If you want to speed up a reaction, you could increase the energy of the reactants by increasing their temperature, or you could add...

This animation shows a solid state catalysis. This animation shows the solid state catalytic hydrogenation of an alkene. This animation shows the basic function of a enzyme as a catalyst. This animation shows the change in potential energy as two molecules collide.

2014年12月31日 · Animation shows what takes place on the molecular level in a catalyzed reaction. Potential energy curves show the relationship between uncatalyzed and catalyzed reactions. Collaborator: Professor Richard E. Powell, University of California, Berkeley. Produced in cooperation with the Manufacturing Chemists' Association. The film...

In the accompanying animation, we look at a reaction in which an enzyme holds a substrate molecule at the enzyme's active site and facilitates the molecule's conversion into a product. We will examine the relative rates of this reaction in the presence or absence of the enzyme, as well as in the presence of enzyme inhibitors.

Catalysis of Enzymes. The process of enzyme catalysts is shown in this animated video. To undergo a reaction the molecule must overcome a energy barrier which some times can be produced by putting heat from outside.

2022年2月3日 · Enzymes are involved in essential biological cellular processes in all living organisms. This animation provides a visual explanation about how enzymes catalyse cellular processes.
