biological molecules

• biological molecules


  building blocks to make cells and other key structures required to make living organisms
• biological catalysts


  speed up reactions without being used up in reactions
• calorimetry


  energy from food
• digestive enzymes


  break down large molecules into smaller molecules
• catalyst


  substance that increases the speed of a reaction without being changed or used in the process
• enzymes


  speed up metabolism or chemical reactions in the body
• metabolism


  whole sum of reactions that occur throughout the body with each other that provide the body with energy
• peristalsis


  circular muscle contraction to move the bolus (food) in the gut
• denaturing enzymes


  an enzyme that has lost its normal 3D structure and therefore it is no longer able to function
• synthesis reaction

• decomposition reaction


  breaking down of a more complex substance into 2 or more simple substances
• optimum


  conditions under which a particular enzyme is most active
