1) Which of the following statements about transport into the mitochondria is FALSE?
a) The signal sequence on proteins destined for the mitochondria is recognized by a receptor protein in the outer membrane of the mitochondria.
b) Proteins that are transported into the mitochondria are unfolded as they are being transported.
c) Transport of proteins into the mitochondria requires SRP and the SRP receptor.
d) After a protein is made in the cytosol it must move through two protein translocators to reach the inner mitochondrial matrix.
2.Which coat protein is involved in vesicle formation during endocytosis â vesicle forms from plasma membrane and fuses with endosomes?
a) COPI
b) COPII
c) v-SNARES d) Clathrin
3. Which of the following statements about vesicular membrane fusion is TRUE?
a) Membrane fusion does not always immediately follow vesicle docking.
b) The interactions of the v-SNAREs and t-SNAREs pull the vesicle membrane and the target organelle together so that their lipids can intermix.
c) NSF and SNAP disassemble the SNARE complex so the SNAREs can be recycled.
d) All of the above are true.
