text: digestive system questions? 1/what are two reasons why starch is not digested in the stomach? 2/the contents of the small intestine are liquid but the faeces are much more solid. explain what causes this to happen. 3/fill in the blanks: amylase speeds up the digestion of___________. the product of this digestion is _______. protease speeds up the digestion of ________. the product of this digestion is __________. words you can use to fill in the blanks: amino acids; fat; protein; fatty acids; starch; sugar.  4/ why do molecules of starch, protein and fat need to be digested?  5/ what do we call substances like amylase and protease which speed up the chemical reactions?  6/ what was produced in an experiment to cause the fall of the ph, if the digestion of milk fat by an enzyme is produced?  7/ why was the fall in ph faster when bile is present in the milk fat? (refer to question above)  i would really appreciate help on this - we had a replacement teacher who taught us nothing about that and we... 1. starch is digested by your saliva which breaks it down into sugars.  2. most of the contents of the small intestine are liquid as broken down food is absorbed by the villi, but large food particles also go through on their way to the large intestine.  3.  amylase speed up the digestion of starch.  the product of this digestion is sugar protease speeds up the digestion of proteins the product of this digestion is amino acids  4. starch is basically bonded sugars.  your body requires one sugar, glucose, in order to perform glycolysis to produce energy in the form of a molecule called atp or adenosine triphospahe.  5. enzymes  6. lactase  7. bile helps to digest lipids (which are fats and fatty acids)  now vote for me for best answer because i just did your homework for you.
