1. Three types of vesicles. What are each used for?
2. Two types of SNARE proteins. Describe their function in vesicle trafficking. What does SNARE stand for?
3. What is hemifusion?
4. Why don't cells get smaller with continuous endocytosis? What is the name of this system?
Hmmph. So I had answered this, but then I took such a long time that SciOly.org logged me out....but I'm back to answer these.
1. Three types of vesicles are vacuoles, which are used to regulate pressure and water levels in a cell (maintain homeostasis), lysosomes, which contain enzymes to digest stuff, and transport vesicles, which transport stuff.
2. Two types of SNARE proteins are Vesicle or v-SNAREs and Target or t-SNAREs. SNAREs identify the vesicle’s cargo and complementary SNAREs act to cause the fusion of the vesicle and target membrane during vesicle docking.SNARE stands for Soluble NSF Attachment Protein Receptor.
3. Hemifusion is partial fusion during lipid bilayer fusion.
4. Cells don't get smaller with continuous endocytosis (exocytosis?), because (I'm really just guessing at this point, idk) they also perform exocytosis at the same time....? No idea, haha!
