,The type of bond that forms to join monomers (such as sugars and amino acids) into polymers
(such as starch and proteins) is a(n) __________ bond.

Covalent - CORRECT ANSWER - Covalent
Generally, animals cannot digest (hydrolyze) the glycosidic linkages between the glucose
molecules in cellulose. How then do cows get enough nutrients from eating grass?
The flat teeth and strong stomach of herbivores break the cellulose fibers so that the cows get
enough nutrition from the cell contents.
They have to eat a lot of grass.
Cows and other herbivores are exceptions and make some cellulose-digesting enzymes.
Microorganisms in their digestive tracts hydrolyze the cellulose to individual glucose units.
All of the listed responses are correct. - CORRECT ANSWER - Microorganisms in their
digestive tracts hydrolyze the cellulose to individual glucose units.
In what polysaccharide form do plants store glucose to be available later as an energy source?
, fatty acids
starch
protein
glycogen
cellulose - CORRECT ANSWER - starch

C51H98O6
C45H84O8PN
C6H12O6
C22H49O10N5
C25H43O8 - CORRECT ANSWER - C6H12O6 (CH2O)
At a conference, the speaker's grand finale was sautéing mealworms (insect larvae) in butter and
serving them to the audience. They were crunchy (like popcorn hulls) because their exoskeletons
contain the polysaccharide __________.
cellulose
