`Name:______________________________#___
This is a model of a __________________________________. There are __________ subunits present. Another name for a subunit is
_________________________. If this is a model of starch , the whole thing is an example of a ________-saccaride. Each individual subunit is
then called a ________________________________. The word saccharide refers to ________________. C6H12O6 is called a simple sugar
or ___________________. The lab test performed for simple sugars used __________________________ solution as the
____________________________. It turned from _______________________ to ___________________________ when the test tube was
___________________________. The test performed for starch used _______________________________. The solution turned from red to
____________________ if the test was positive.
This molecule below ( in the long form) would test ______________(+ or -) with Benedict’s solution and test ______________(+ or -) with
Lugol’s Iodine solution.
If you wanted to break up the long chain you could use an_____________________. An example of an enzyme is __________________. This
enzyme is found in your __________________________. It will break down the complex__________________ found in a cracker to a
simple______________________. Design an enzyme shape that could be used to digest the starch. Draw it in an appropriate spot of the
molecule below.

These are several different models of the monomers that make up a protein.
These monomers are called _______________________________. In order for them to be joined together, a water
molecule must be removed. One part of the water molecule is the H and the other part is the_______________. When
water is created as a by-product in the joining of the molecules, the process is called dehydration _________________.
Cut out the molecules and put them in this order: cysteine—valine--glycine—serine—phenylalanine-alanine—
You will now join them together by cutting out the necessary –OH and –H. You only cut them out when
you join 2 together. Cut on the solid black lines of the–OH and –H. Save the -OH and –H and put them
next to each other to make water. How many water molecules do you make from joining these 6
subunits?___________________. What do you notice about the ends where you join the 2 subunits?
___________________________________. The bond that joins the tow amino acids together is called a
____________________ bond. Many amino acids joined together are called a
___________________________________. It takes about _____________ amino acids joined together
to make a _______________________. Three uses of proteins in the human body are:
_______________________________________________________________________________.
