biomolecules/carbon compounds lab? For each
indicator list the substance that it tested for.
The indicator for proteins was Biurets Reagent.
The indicator for lipids was Sudan III.
The indicators for carbohydrates were Iodine
(starch) and Benedicts (monosaccharides).
You must answer in complete a
sentence!

rate of reactions, control cell processes, help
form bones and muscle, transport
substances into and out of the cell, and help
fight disease.
Answer in complete sentences!
8. What are the functions of carbohydrates,
lipids, and nucleic acids?
Living organisms use carbohydrates as their
main energy source.
Lipids are stored energy in living organisms.
Nucleic acids store and transmit hereditary
or genetic information.
You must answer in a complete
sentence!
9. How do enzymes help speed up chemical
reactions in living organisms?
Enzymes speed up chemical reactions by
lowering the activation energy of a reaction.
You must answer in complete
sentences!
10. What is a validity measure?
A validity measure is a step taken during an
experiment to ensure that the data collected
shows what it is supposed to show. For
example, calibrating equipment, washing
glassware and running positive/negative
controls are all validity measures.
Write a hypothesis for this
experiment!
11. You want to know if studying improves grades.
To test this you take 50 sophomores with the same
GPA (3.0) and have half of them review biology
concepts using flashcards for 10 minutes a day; the
other students do not (they play Pacman instead).
You will compare the average test scores of the two
groups.
If 25 sophomores (3.0 GPA) review biology concepts with
flashcards for 10 minutes a day while 25 sophomores (3.0 GPA)
play Pacman instead, then the reviewing group will have a higher
test average than the Pacman group because reviewing helps
improve long-term memory of facts and concepts.
