Ident: Q Flashcards
where is protein digested?
stomach and small intestine (duodenum)
where is protein absorbed?
small intestine (jejunum)
protein energy?
not the main energy source, inefficient energy source for a horse
where is fibre digested?
caecum
where is fibre absorbed?
colon
energy produced by fibre?
after being converted to VFA can be stored or used straight away for slow release (aerobic) energy
where is starch digested?
small intestine (duodenum)
where is starch absorbed?
small intestine (jejunum)
energy produced by starch?
converted to glucose that can be stored or used as fast release (aerobic and anaerobic)
where is sugar digested?
SI (duodenum)
where is sugar absorbed?
SI (jejunum)
energy produced by sugar?
converted to glucose, can be stored or used as fast release (aerobic and anaerobic)
where is fat digested?
SI (duodenum)
where is fat absorbed?
SI (jejunum)
energy produced by fats?
converted to fatty acids that can be stored or used for slow release (aerobic) energy
explain how protein is digested in the stomach and SI
food mixed with pepsin (enzyme that aids protein digestion) and hydrochloric acid (helps to break down solid particles)
enzymatic degradation of protein by protease (pancreatic secretion)
explain how fibre is digested in the caecum and absorbed in colon
plant material broken down by the microbial population. Fibre is converted to VFA and the passed into the colon where absorbed.
explain how starch is digested in SI
enzymatic degradation of starch by amylase (pancreatic secretion)
explain how sugar is digested in SI
amylase
explain how fats are digested in SI
bile released from the liver emulsifies fats and stimulates lipase secretion from the pancreas. Enzymatic degradation of fat/oil by lipase
capacity of stomach, SI and LI
stomach (18L)
SM (55-70L)
LI (86L)
