D Botulism can cause muscle weakness, paralysis and the inability to breath. This is due to the action of botulinum toxin, which cleaves SNARES in affected cells. What process in affected cells is blocked by the destruction of SNARES? O Fusion of secretory vesicles to the plasma membrane and neurotransmitter release. O The initial tethering of neurotransmitter-filled secretory vesicles at the membrane. O Endocytosis of neurotransmitters for reuse. O Transport of neurotransmitter-filled secretory vesicles towards the membrane. Question 3 During oxidative phosphorylation, reactive oxygen species are sometimes released that can damage mitochondria. What is the name of the process by which a cell can remove/eliminate damaged mitochondria? O Phagocytosis Pinocytosis O Autophagy 2 pts O Apoptosis
Which statement accurately describes the modification process for plasma membrane glycoproteins? O Glycosylation and oligosaccharide modification occurs solely in the Golgi apparatus. O None are correct because only cytosolic proteins are glycosylated. O Glycosylation and oligosaccharide modification occurs solely in the endoplasmic reticulum. O Glycosylation begins in the ER and modification of the attached oligosaccharide continues in the Golgi apparatus. O Glycosylation begins in the Golgi apparatus and modification of the attached oligosaccharide continues in the ER Question 5 Which of these is not connected to the endomembrane system by vesicle trafficking? O lysosomes O Golgi apparatus O mitochondria O endoplasmic reticulum O All of these are connected by vesicle trafficking. 2 pts
