Endothermic reaction
100
Name one monosaccharide we discussed in class
glucose, fructose, galactose
200
Which macromolecule has the element phosphorus???
Nucleic acid

Why are lipids important in the function of a cell?
They make the cell membrane waterproof
200
Where do chemical reactions take place on an enzyme?
the active site
200
Is this an endothermic or exothermic reaction?
exothermic
200
What is the difference between monomers and polymers?
Polymers are multiple monomers put together.
300
Which macromolecules have only carbon, hydrogen, and oxygen?

300
Which 2 macromolecule would you find in the blubber of a walrus?
lipids and nucleic acids
300
Give 3 factors that could influence or affect the function of an enzyme.
temperature, pH, and substrate concentration
300
Which line is showing the experiment without a catalyst?
dotted
300
What is the difference between competitive and non competitive inhibition?
competitive- the wrong substrate binds to the active site so the enzyme can't function
non competitive- the wrong substrate binds to an area on the enzyme that is not the active site, which changes the shape of the enzyme so it can't function
