In this video Paul Andersen explains how the three types of catalyst classes act to speed up reactions. Acid-base catalysts either add or remove a proton from one of the reactants. Surface catalysts provide active sites where reactants...

Enzyme Basics & How Do They Lower Activation Energy

This video provides a comprehensive overview of the human digestive system, including the two types of digestion (mechanical and chemical), the three basic food types (carbohydrates, proteins, and fats), and the enzymes involved in...

This video is a lecture presentation about digestive enzymes and how our bodies process the food we eat to extract important nutrients from it. The presenter explains the two types of digestion - mechanical and chemical, and focuses on...

Through animation and video footage students will learn that there are two basic types of catalysts, heterogeneous and homogeneous. Students will come to understand that catalysts have many practical applications and that scientists use...

This video is a lecture presentation on the human digestive system. The lecturer begins by defining digestion and explaining the two types, chemical and mechanical digestion, and how they work together. The three basic food types,...
