Web26 nov. 2024 · 3.1 Biological molecules. All life on Earth shares a common chemistry. This provides indirect evidence for evolution. Despite their great variety, the cells of all living organisms contain only a few groups of carbon-based compounds that interact in similar ways. Carbohydrates are commonly used by cells as respiratory substrates. WebThe key (substrate) has a specific shape (arrangement of functional groups and other atoms) that allows it and no other key to fit into the lock (the enzyme).

WebLesson Explainer: Enzyme Action. In this explainer, we will learn how to describe the properties of enzymes and outline the lock-and-key theory of enzyme action. All chemical reactions require an input of energy to get started, called the activation energy. Catalysts speed up the rate of reactions without being used up themselves.
