Gut Bacteria & Digestion

Science · Organisms & Life Processes · conceptual

Explain the role of gut microbiome bacteria in digestion, including breaking down dietary fibre and contributing to a healthy gut environment

Sign in to track this

What mastery looks like

  • Explains that many gut bacteria are beneficial, not harmful
  • Describes what gut bacteria do that human digestive enzymes cannot (e.g. break down fibre)
  • Explains what might happen if the gut microbiome is disrupted

Check your understanding

If Gut Bacteria & Digestion heard that there are billions of bacteria living in our gut, could they explain why that's actually helpful for digestion rather than something to worry about?
