mouth-breaks down food. o esophagus. tube to stomach. Stomach- producesaads to kill baciena and break down food.. liver - produces bile with lipase small intestine- breaks food more large intestine = absorbs water pancreas = produces amylase & protease. Digestion turns large insoluble molecules injo smaller soluble ones biology • ingestion • muscles contact in oesophagus-peristalsis • Stomach makes food into acid liver makes bile, bilestored in gall bladder. · small intes absorbs huments • large inter absorbs water • faeces stored in rectum egestion = pushed out of anys. 3 Lock and key Model ($ enzyme + substrate enzyme enzyme + subškate tproduct.

They cause the break down of substrates during digestion.. "amylase - carbs into glucose profecse - proteins into amino lipase - fats in to fatty acids. Amylase salivary glands, pancrease, small intestine protease stomach, pancrease, small intestine. lipase -pancreas, small intestine. The food diffuses (absorption) from the small intestine into the blood and diffuses into cells. no Tissue a group of cells with similar structure and function working together. organ - a collection of tissues working together to perform a specific function. eg. Pancreas is an organ that makes hormones to control blood sugar, and some of the enzymes to digest food. organ system - a multicellular organism is made up of a mumber of organ systems working together.
