How do our bodies use fats?
To store energy To protect organs As insulation To store vitamins All of the above
14
In order to form a protein, what has to happen?
Multiple monosaccharides have to join together by losing water Multiple disaccharides have to join together by adding water Multiple monomers have to join together by losing water Multiple amino acids have to join together by adding water
15
True or false: a condensation reaction is the same as a hydrolysis reaction.
16
When a substrate fits into an enzyme and the enzyme forms around the substrate this…
Is called the Lock and Key Hypothesis A coenzyme is needed Is called the Induced Fit Hypothesis An inhibitor is present
17
What happens in noncompetitive inhibition?
The inhibitor competes with the substrate for the active site The inhibitor bonds permanently with the enzyme The inhibitor reversibly binds with the substrate The inhibitor binds with the enzyme at a place other than the active site
