Questions & Step-by-Step Solutions

What is the role of enzymes in biological reactions? (2023)
  • Step 1: Understand that enzymes are special proteins found in living organisms.
  • Step 2: Know that enzymes help speed up chemical reactions in the body.
  • Step 3: Learn that every chemical reaction needs a certain amount of energy to start, called activation energy.
  • Step 4: Realize that enzymes lower this activation energy, making it easier for reactions to happen.
  • Step 5: Conclude that by lowering the activation energy, enzymes help reactions occur faster and more efficiently.
