2. Melanosomes are specialized lysosomes that store pigments for eventual release by exocytosis. Various cells such as skin and hair cells then take up the pigment, which accounts for their characteristic pigmentation. Mouse mutants that have defective melanosomes often have pale or unusual coat colors. One such light-colored mouse, the Mocha mouse has a defect in the gene for one of the subunits of the adaptor protein complex AP3, which is associated with coated vesicles budding from the trans Golgi network. How might the loss of AP3 cause a defect in melanosomes

Which survival need shortage would most affect articular cartilage's ability to rebound after joint compression, and why does it have this effect? which survival need shortage would most affect articular cartilage's ability to rebound after joint compression, and why does it have this effect? nutrients, since the majority of cartilage is made out of polysaccharide glycosaminoglycans (gags). water, since it makes up to 80% of cartilage's content and cushion articular bone surfaces. normal body temperature, since higher temperatures would slow down necessary biochemical reactions. oxygen, since cartilage cells receive this gas directly from nearby blood vessels?
