Front 1

enzyme

Back 1

large protein molecules produced by body cells, they are catalysts

Front 2

catalysts

Back 2

increase the rate of chemical reaction without themselves becoming part of the product

Front 3

hydrolases

Back 3

digestive enzymes are hydrolytic enzymes or this ..

Front 4

substrates

Back 4

the molecules which are acted upon by enzymes

Front 5

controls

Back 5

specimens or standards against which experimental samples are compared

Front 6

salivary amylase

Back 6

enzyme produced by the salivary glands and secreted in the mouth

Front 7

positive starch test

Back 7

trying to find out if starch is present in your sample, you add iodine, if the solution turns blue-black this is a ....

Front 8

negative starch test

Back 8

trying to find out if starch is present in your sample, you add iodine, if the solution stays its original color of brown this is a ....

Front 9

positive sugar test

Back 9

trying to find out if sugar is present, you add benedict's solution, the solution turns green-orange this is a...

Front 10

negative sugar test

Back 10

trying to find out if sugar is present, you add benedict's solution, the solution does not change this is a....

Front 11

enzyme assay

Back 11

the chemical method of detecting the presence of digested substances

Front 12

cellulose

Back 12

plant sugar, humans can break down to an extent

Front 13

trypsin

Back 13

an enzyme produced by the pancreas, hydrolyzes proteins to small fragments

Front 14

BAPNA

Back 14

synthetic trypsin substrate consisting of a dye covalently bound to an amino acid. fake protein

Front 15

trying to find out if trypsin has broken down a peptide bond, the sample turns yellow, this indicates...

Front 16

negative hydrolysis test

Back 16

trying to find out if trypsin has broken down a peptide bond, the sample remains clear, this indicates...

Front 17

glucose

Back 17

sugar, disaccharide

Front 18

peptidase

Back 18

an enzyme that breaks down protein

Front 19

pepsin

Back 19

enzyme released by the chief cells in the stomach, breaks down protein

Front 20

pancreatin

Back 20

the enzymatic product of the pancreas, includes enzymes that digest proteins

Front 21

pancreatic lipase

Back 21

this enzyme hydrolyzes fats and oils to there component to their component monogylcerides and two fatty acids, or glycerol and 3 fatty acids

Front 22

optical density

Back 22

the measure of the amount of light absorbed by solution. This precisely measures how much BAPNA digestion occurred

Front 23

bile

Back 23

a secretory product of the liver, not an enzyme, this emulsifies fats, breaks them down. Emulsified fats provide a larger surface area for enzyme activity

Front 24

deglutition (swallowing)

Back 24

this occurs in two phases buccal (voluntary) and pharyngeal-esophageal (involuntary)

Front 25

segmental movement

Back 25

the local constrictions of the organ that occur rhythmically. Function by increasing the rate of absorption by mixing foodstuffs and digestive juices and in propulsion of food into the small intestine

Front 26

peristaltic movement

Back 26

major means of propelling food through most of the digestive vicera. Waves of contraction followed by waves of relaxation. involved more in food movement the mixing
