What is produced when yeast respires anaerobically?

Answer and explanation

Correct answer: A. Ethanol and carbon dioxide, together with a small amount of ATP

  1. Step 1: Yeast is a fungus that ferments sugar when oxygen is absent. Step 2. The products are ethanol and carbon dioxide, and only a little energy is released. Answer: ethanol and carbon dioxide. Why not the others: lactic acid is made in animal muscle, oxygen is not a product, and carbon dioxide with water is aerobic respiration.
