How do enzymes affect chemical reactions? [Facts!]

WebHow does your body speed up these important reactions? The answer is enzymes. Enzymes in our bodies are catalysts that speed up reactions by helping to lower the activation energy needed to start a reaction. Each enzyme molecule has a special place called the active site where another molecule, called the substrate, fits. WebThis article highlights how enzymes acts as catalysts to speed up chemical reactions within cells. As we consider how biochemistry can explain how cells function and provide solutions to some of society’s major challenges, it is important to think about how reactions take place inside cells. jfe スチール 年収 高卒 https://4ceofnature.com
