The diagram represents an experiment investigating how protease digests the protein in egg albumen. The protease came from a human stomach. In which test-tube will the protein be digested most quickly?
- Aegg albumen + protease
- Begg albumen + dilute hydrochloric acid
- Cegg albumen + dilute hydrochloric acid + protease
- Degg albumen + dilute hydrochloric acid + boiled protease
