During the process of digestion, complex insoluble macromolecules must be hydrolysed into smaller, soluble monomers before they can be absorbed into the body.
Complete the table below by identifying the missing terms for (i), (ii), and (iii).
| Large food molecule | Digestive enzyme | Major product(s) of digestion |
|---|---|---|
| (i) | Amylase | Maltose |
| Protein | (ii) | Amino acids |
| Lipid | Lipase | Fatty acids and (iii) |
Following chemical digestion, the resulting monomeric subunits are absorbed across the specialized wall of the ileum (small intestine). Describe three distinct structural adaptations of the ileum wall that facilitate the highly efficient absorption of these nutrients.
