1. Which of the following is a true statement
regarding protein sorting?
The mRNA of a secreted protein is localized to
the ER prior to translation
The ribosomes associated with the ER can only
translate mRNAs for secreted or membrane proteins
All proteins that need to reach a destination
other than the cytosol contain an N-terminal signal

After the N-terminal signal is translated a stop
codon halts translation until the ER is reached
A vesicle going from the Golgi to the ER will have all the
following except for?
COPI coat proteins
t-SNAREs
v-SNAREs
KDEL-containing proteins
Two proteins need to interact physically with each other.
Protein 1 is rich in lysine, arginine, and histidine. Of the
following, which would protein 2 need in its sequence in order to
make this interaction possible? Select the two options that
apply
Proline

Asparagine
Glutamic acid
Glutamine
Aspartic acid
An equal amount of two enzymes (A1 and A2) were put in
individual test tubes. The Km values are as follows: A1<A2. In
which of the following conditions should you expect to see an equal
amount of product from both tubes?
Competitive inhibitor added only to A2

Competitive inhibitor added only to A1
Higher concentration of substrate added to A2
than to A1
Equal concentration of substrate added to both
tubes
Higher concentration of substrate added to A1
than to A2
If there are equal amounts of an ion on both sides
of the membrane there will be no transport even if a channel is
open
True
False
