BIO 1404: POST LAB QS QUESTIONS
WITH COMPLETE SOLUTIONS!!
1 of 89
Term
was each enzyme specific for one substrate or was there some
overlap? why?
Give this one a try later!
yes, we said that at a higher temp it each enzyme solution makes each
would increase the co2 production more acidic or basic
, it wouldn't be a problem yes, because enzymes
because it is specific to only are specific to one
one substance reaction
Don't
know?

Term
Why does the solution change to a yellow color after you
blow on it?
Give this one a try later!
CO2 reacts with oxygen to CO2 reacts with glucose to
become carbonic acid become carbonic acid
CO2 reacts w/water CO2 reacts with light to become
to become carbonic acid
carbonic acid
Don't know?

Term
what would happen if you increase the substrate
concentration?
Give this one a try later!
, speed up the reaction have no effect
have no effect on the reaction rate. slow down the reaction
Don't know?

Term
Do free amino acids have peptide bonds?
Give this one a try later!
no free amino acids do
not react positively and
it yes, free amino acids are
reflected in our always in a bonded state
experiment when the
amino acid solution
tested negative
no, free amino acids only yes, free amino acids form
react with sugars and not with strong peptide bonds in
proteins solution
Don't know?

Term
How does the rate of O2 production differ when
calculated using just the endpoint data (20 minutes) verses
plotting a trendline? why?
Give this one a try later!
the trendline is consistent
the trendline shows a
while the plotted data
random rate of change
isn't bc the trendline is
an avg rate of change
from the data
the trendline is less reliable the endpoint data is always more
than individual data points accurate
Don't know?

Are all three threads in focus at 40X?
Give this one a try later!
