- Enzymes and Digestion
- Digestion is the process of breaking down food into substances that can be used by the body
- Chemical composition of food
- Many molecules in our food are polymers (proteins, carbs)
- Large, complex molecules composed of long chains of monomers - small, basic molecular units
- Physical Digestion
- Food is broken down into smaller pieces by teeth
- Moves to stomach where it is broken down further by churning movement of stomach muscles
- Breaking food down into smaller pieces gives it a larger SA - makes chemical digestion faster
- Moves to stomach where it is broken down further by churning movement of stomach muscles
- Food is broken down into smaller pieces by teeth
- Chemical Digestion
- Break down large, insoluble molecules into smaller, soluble ones
- HYDROLYSIS
- Splitting up of molecules by adding water to the chemical bonds that hold them together
- Name of enzyme is hydrolases
- Food molecules are built up again into large molecules, these molecules are incorporated into body tissues
- Assimilation: incorporating absorbed molecules into body tissues
- Food molecules are built up again into large molecules, these molecules are incorporated into body tissues
- Name of enzyme is hydrolases
- Splitting up of molecules by adding water to the chemical bonds that hold them together
- HYDROLYSIS
- Break down large, insoluble molecules into smaller, soluble ones
