The human digestive system relies on various specialized biological catalysts to hydrolyze large, insoluble food molecules into smaller, soluble nutrients that can be absorbed into the bloodstream.
The table below outlines key information regarding different digestive enzymes.
Complete the table by giving the missing information for (i), (ii), (iii), and (iv).
| Type of enzyme | Example | Site of production | Optimum pH |
|---|---|---|---|
| (i) | pancreatic lipase | pancreas | (ii) |
| carbohydrase | pancreatic amylase | (iii) | 8.0 |
| protease | pepsin | stomach | (iv) |
Explain why pancreatic amylase and pepsin require different optimum pH levels to function efficiently.
