Salivary glands: Salivary glands secrete the enzyme amylase in saliva, allowing it to break down carbohydrates. This process facilitates digestion and absorption of essential nutrients in the body. 2. Gullet: In the digestive system, the Oesophagus (food pipe) is located within the Gullet. WebInto the enzyme fits certain molecules like a key. The enzyme begins to break down the molecule once this has happened. When the molecule is broken up the enzyme remains the same shape.---picture of this---Enzymes work best at low temperatures (from 5°C-45°C). The optimum temperature for enzymes is between 37°C- 40°C (body temperature). the paleobiology database paleobiodb.org
