breaking down food
Cards in this deck (38)
- 1the digestive system breaks down large insoluble molecules into ?smaller molecules
- 2what does the chemical breakdown of food depend ondigestive enzymes
- 3name the 3 types of food moleculescarbs, proteins and fats
- 4name some carbs ?bread potatoes rice
- 5what are carbs made ofh2o , c ,o2
- 6what is the simplest carbsugar
- 7how does sugar develop into starchit is built up
- 8name a complex carbstarch
- 9what are digestive enzymes that break down carbs are calledcarbohydrase
- 10name another group of carbohydrasesamylase
- 11what is amylases jobbreak down starch into sugar
- 12when starch is broken down into sugar wheere can it be absorbedsmall intestine
- 13starch into sugar can be broken down in g_______glucose by other carbohydrates
- 14where is amylase present and made and releasedsaliva and made in the pancreas and released into the small intestine
- 15what enzyme breaks down proteinsprotease
- 16describe the process protease to amino acidsprotease(enzymes) -->shorter chains -->amino acids
- 17name a protease in the stomachpepsin
- 18what type of conditions does pepsin work best atacidic
- 19what is the ph of the acid produced in the stomachph 2-3
- 20what does the optimum of a ph meanreached its limit everything will stay at a constant
- 21why is ph 2-3 a good condition for pepsinit can break down protein as fast a possible
- 22is the small intestine an alkaline or antacidalkaline
- 23what is the small intestines best working conditionph 8
- 24what enzymes digest fatslipases
- 25what is produced by lipase'sfatty acids and glycerol
- 26what is formed by fats and oils trying to mixglobules
- 27globules form?watery digestive juices
- 28what do large globules have ?small surface areas to volume ratio
- 29largue globules have small surface area to volume ratio meaning?lipases can ony break fat molecules slowly
- 30where is bile fromgall bladder
- 31what forms an emulsionbile breaks down the large globules into tiny droplets
- 32bile e______ fatemulsifies
- 33what is good about having a large surface areathe smaller droplets allow the lipase break down the fat molecules rapidly
- 34when is bile releasedafter a fatty meal
- 35what makes faeces brownBILE
- 36what makes faeces brownBILE
- 37what word ending are usually enzymease
- 38name two jobs for bileneutralises the acid from the stomach.
produces a slightly alkaline environment
