>1000 Correct Answers How many proteins are required to see
life sustained in small organisms like bacteria?
1 Correct Answers Ideally, control and experimental groups
should differ in how many variables?
1. A cargo of proteins sythnesized in the ER binds to the
receptors in the ER membrane
2. Coat proteins bind, the vesicle begins to bud from the
membrane, and V snares are incorporated
3. The vesicle continues to bud and eventually pinches off of the
ER membrane.
4. After vesicle is released, the coat is shed.
5. The vesicle binds to the target membrane by a V-snare/T-
snare interaction.
,6. The vesicle fuses with the target membrane to deliver the
protein cargo to its target destination Correct Answers What are
the steps involved in co-translational protein sorting from
vesicles in the endoplasmic reticulum?
1. A protein destined for the mitochondrial matrix is made in the
cytosol, where chaperone proteins keep in in an unfolded state.
2. A matrix-targeting sequence on the protein binds to a receptor
on the outer mitochondrial membrane
3. Cytoplasmic chaperone proteins are released as the protein is
transferred to a channel in the outer mitochondrial membrane.
4. The protein is then transferred to a channel in the inner
mitochondrial membrane.
5. Chaperone proteins in the mitochondrial matrix bind to the
protein as it enters the matrix.
6. The matrix-targeting sequence is cleaved by an enzyme in the
matrix, the chaperones are released, and the protein folds into its
active structure. Correct Answers What are the steps involved
in post-translational sorting of a protein to the mitochondrial
matrix?
1. Glycogen
2. Starch
3. Cellulose Correct Answers Rank the following
polysaccharides of glucose in order of most branched form to
least branched form:
1. SRP binds to the ER signal sequence on the polypetide and
pauses translation
2. SRP binds to a receptor in ER membrane and docks the
ribosome over a channel.
, 3 SRP is released and translation resumes
4. The growing polypeptide is threaded through the channel and
across the ER membrane.
5. The polypeptide is released into the ER lumen Correct
Answers What are the steps in cotranslational protein sorting?
A difference in charged ion balance on either side of a cellular
membrane. Correct Answers Define membrane potential
A eukaryotic cell has a nucleus; a prokaryotic cell does not.
Correct Answers What is the difference a prokaryotic cell and a
eukaryotic cell?
A few hundred to a few thousand Correct Answers How many
mitochondria are typically found in a Eukaryota cell?
Above 7 has a lower [H+] and is basic Correct Answers What is
a base?
Actin filament Correct Answers two intertwined strands of
protein often found near the plasma membrane
Active Transport Correct Answers Energy source used to drive
transport from low to high concentration.
All organisms are composed of one or more cells; Cells are the
smallest unit of life; Cells come from pre-existing cells via cell
division Correct Answers List the three principles of the cell
theory:
