Darwinism : The Most Important Contribution of the Victorian Era. Charles Darwinâs revolutionary idea of evolution sparked dramatic debate in the scientific and, most especially, religious communities, as well as inspiring a new wave of thought in the minds of the world. There was also plenty of controversy, particularly from the many believers of creationism during the Victorian era.
1. Proteases Digestion of proteins is initiated by pepsin in the stomach, but the bulk of protein digestion is due to the pancreatic proteases. Several proteases are synthesized in the pancreas and secreted into the lumen of the small intestine.
Specialised cells in the stomach wall produce large amounts of hydrochloric acid and this means that the stomach is about pH 2. The low pH provides an environment that allows the protease enzyme pepsin to be active. This starts the digestion of proteins as the food is churned around in the stomach.nzymes in the digestive system speed up the breakdown of the food. Enzymes are made in many places along the digestive system. 1  Carbohydrases-enzymes which break down carbohydrates into simple sugars. 2  Proteases-enzymes which break down proteins, ending up with amino acids.
