Reactions

Activation Energy, Coenzymes, Heat
This lesson discuses the minimum energy that must be put into a chemical system.What happens when a reactant goes to a product, the activation energy that passes to get from the reactant to the product. What a catalyst does, how it decreases. An explanation of how enzymes are large proteins made up of polypeptide chains. What vitamins function as coenzymes and how it helps the enzyme increase rate of reaction. What happens when heat enzymes come into play and what blocks enzymes.

4.6 Chemical Equations Part E: Photosynthesis
This video shows an animation of photosynthesis and respiration reactions, and how these two are connected in the biological world. It explores the energy relationships between them, and shows how photosynthesis is an endothermic reaction, respiration is exothermic. The value of plants' ability to photosynthesise is emphasised.
