• Why do biological molecules in food have to be digested ?

  Absorption - Need to be broken down into smaller molecules first to be absorbed by our villi and into the rest of our body
• What are proteins broken down into ?

• Which enzyme breaks down maltose ? What is it broken down into ?

  Enzyme: Maltase Product : Two Glucose molecules

  Broken down by amylase into maltose molecules
• What is bile and how does it help with lipid digestion ?

  Bile is a yellow - greenish liquid released from gall bladder

  • It emulsifies lipids which increases the surface area for lipase enzymes to break them down
