Why are v-SNAREs recycled from the plasma membrane but not t-SNAREs? How does this reconcile with how SNAREs mediate vesicle fusion?
a) v-SNAREs are recycled because they are involved in vesicle fusion events, whereas t-SNAREs are not.
b) v-SNAREs are recycled due to their role in endocytosis, while t-SNAREs are degraded in lysosomes.
c) v-SNAREs are recycled to maintain cellular homeostasis, while t-SNAREs are degraded for regulatory purposes.
d) v-SNAREs are recycled because they facilitate vesicle trafficking, while t-SNAREs are degraded as part of membrane turnover.
