B3 Organisation And Digestive System Flashcards
Tissues
Group of cells with aimiliar struxture and function working for together.
Organs
Organs are collections of tissues. Each organ contains several tissues all working together to perform a specific function.
Organ system
A whole multicellular organism is made up of organ systems working together. Organ systems are groups of organs that all work together to perform specific functions
Catalysts
People use special chemicals known as catalysts to speedw reactions. A catalyst speeds up a chemical reaction but it is not used up in the reaction. You can use catalysts over and over again.
Digesting enzymes
Your digestibe enzymes work outside your cell. They are produced by specialised cells in glands and in the lining of your digestive systems
Digesting carbohydrates.
Starch is one of the most common carbohydrates that we eat. Its broken down into sugars in your mouth and small intestine. This reaction is catalysed by an enzyme called amylase.
Amylase
Amylase is produced in your salivary glands so the digestion of starch starts in your mouth. Amylase is also made in the pancreas .
Digesting proteins
The breakdown of protein foods such as acids is catalysed by protease enzymes. Proteases are produced by your stomach, your pancreas, and your small intestine.
