BCH4024 OC Sp25 E2 Q41: Common genetic causes of severe adult obesity are loss-of-function mutations in the melanocortin signaling pathway. One effect of these mutations is aberrantly low levels of activated protein kinase A (PKA) in certain cells of the hypothalamus. What type of mutation would most likely produce low levels of activated PKA?

BCH4024 OC Sp25 E2 Q40: If a membrane fatty acid composition resulted in a melting temperature (Tm) or transition temperature of 41°C for the plasma membrane of a hybrid cell, how would the membrane respond to changes in temperature if the cells are induced to express cholesterol?
