Questions & Step-by-Step Solutions

Which enzyme is involved in the Krebs cycle during respiration? (2022)
  • Step 1: Understand that the Krebs cycle is a part of cellular respiration, which helps produce energy.
  • Step 2: Identify that enzymes are proteins that help speed up chemical reactions in the body.
  • Step 3: Learn that the Krebs cycle has several steps, and each step is facilitated by a specific enzyme.
  • Step 4: Recognize that the first step of the Krebs cycle involves the enzyme called citrate synthase.
  • Step 5: Conclude that citrate synthase is important because it helps start the Krebs cycle by combining two molecules to form citrate.
