type, (TRUE )
3. Enzyme concentration describes how fast an enzyme converts a substrate to the product ANS
(False)
4. Based on the background reading of LDH and the muscle types you are studying ANS it is
expected that LDH would be higher in the glycolytic (Fast-twitch) muscle ,(TRUE)
5. The purpose of homogenizing samples after placing them in a lysate buffer is to break open cell
membranes to access proteins from subcellular fractions and organelles ANS (TRUE)
6. The Lowry assay measures protein concentration ANS (True)
7. A student has a Bradford assay standard curve pf y=1.11x + 0.002 and an absorbance value of an
unknown samples of 0.668. The student calculated the protein concentration to be 0.74 ug/ml ANS
(TRUE)
8. The beers-lambert law utilizes the extinction coefficient of a given wavelength. The distance it
passes through the sample and the concentration of the solution to calculate the indirect relationship
between absorption and protein concentration ANS (FALSE)
9. During tissue homogenization protein was the only macromolecule released from the cell
membrane. As well as the organelle membranes and cytoplasm. ANS (FALSE)
, 10. You generally set the absorption of a blank solution in spectroscopy equal to zero before your
experiment so that you do not measure unwanted background absorbance in your cuvette ANS
(TRUE)
11. Freezing and thawing samples is an example of a sample homogenization technique ANS
(TRUE)

16. There will be no significant difference in HSP-70 activity between fish in cold water vs fish in
warm water is an example of a hypothesis ANS (FALSE)
17. When testing more than one variable during an experiment. A multiple group design was the most
appropriate experiments set up ANS (TRUE)
18. If you pipette 50uL of stock muscle cell culture into 250uL of water you have made a 1;5 (5 fold
dilution) ANS false
19. 200uL is equal to 0.2 mL ANS (True)
20. Substrate concentration has a greater effect on reaction rate than enzyme concentration ANS
(FALSE)
