Enzymes and digestion Flashcards
(16 cards)
Why do large food molecules like starch, proteins, and fats need to be broken down by digestive enzymes before absorption?
What enzymes break down starch, proteins, and lipids, and what are the end products of each digestion?
label the alimentary cannel?
give the function of the mouth?
salivary glands in the mouth produce amylase enzymes in the salvia
teeth break down food
give the function of the Oesphagus?
the muscular tube that connects the mouth and stomach.
give the function of the liver?
where the bile is produced
what is the function of the gall bladder?
where bile is stored
what is the function of the large intestine?
also called the colon
where excess water is absorbed from the food
what is the function of the rectum?
the last part of the large intestine
where the faeces (made up of indigestible food) are stored before they bid you a find farewell through anus
what is the function of the small intestine?
produces protease amylase and lipase enzymes to complete digestion
this is also where the nutrients are absorbed out of the alimentary canal into the body
what is the function of the pancreas?
produces protease amylase and lipase enzymes. it releases these into small intestine
what is the function of the stomach
it pummels the food with its muscular walls,
it produces the protease enzyme, pepsin
it produces hydrochloric acid for two reasons
a) to kill bacteria
b) to give the optimum pH for the protease enzyme to work
what does bile do
neutralises stomach acid and emulsifies fat.
what is peristalsis?
how does Villi in the small intestine help with abosrption?
