|
to test for the presence of starch what testing solution would you use? what color would it turn?
|
-Lugols
-from amber to dark blue |
|
|
to test for the presence of simple sugars what testing solution would you use?
|
Benedicts
|
|
|
to test for the presence of protein what testing solution would you use?
|
Biurets
|
|
|
which of the substances that were tested contained simple sugars? why what color did they change?
|
-milk, glucose, maltose
-green, yellow, orange, red |
|
|
which of the substances that were tested contained protein? what color did they change?
|

|
|
How do we know that amylase catabalized the starch?
|
Because less starch particles are visible because starch has been broken down effectively by the enzyme at body temp.
|
|
|
How can you prove the enzyme amylase broke down the substrate?
|
You would add benedicts and boil the solution which turns it a dark orange which verifies that there are disaccarides and trisaccharides present.
|
|
|
After boiling the solution with bennedicts why did it not turn red?
|
because there are no monosaccharides
|
|
|
what is an example of a simple sugar (monosaccharide)?
|
glucose
|
|
|
what is an example of a simple sugar (disaccharide)?
|
lactose, sucrose, maltose
|
|
|
What is an example of a complex sugar (polysaccharide)?
|
starch
|
|
|
what is an example of a protein?
|
milk proteins
|
|
|
what is the substrate for amylase?
|
water and starch
|
|
|
what is the end product for amylase?
|
disaccharides and trisaccharides
|

|
|
|
The kidneys are behind the peritoneum, what is that called?
|

|
|
|
what is the function of the urethra?
|
exits urine into the outside world
|
|
|
what is the function of the renal capsule?

|
|
|
what is the path that urine follows to drain out of the kidneys?
|
minor calyx-->major calyx--> renal pelvis--> ureter
|
|
|
what is the function of the ureters?
|
prevents backflow when bladder fills and ureters crimp
|

|
|
|
what is the process that happens to nutrients after digestion?
|
absorption
|
|
|
what is the molecule produced as a result of an enzymatic process?
|
product
|
|
|
what is the definition of chemical digestion?
|
enzymes breaking down the bonds of food macromolecules
|
|
|
what does starch digest into? by what enzyme?
