Although compartmentalization allows cells to perform a variety of functions, there can be energetic costs to compartmentalization. in particular, cells expend energy to move certain molecules across membranes. in the mitochondria, the transmembrane gradient established by the electron transport chain plays an important role in the movement of molecules across the mitochondrial inner membrane. which of the following processes involve directly expending this gradient to move molecules into the matrix? (select two answers)

import of proteins into the mitochondrial matrix coupled to atp hydrolysis antiport of malate into the matrix and a -ketoglutarate out of the antiport of glutamate into the matrix and aspartate out of the matrix symport of inorganic phosphate and hydrogen ions into the matrix symport of pyruvate and hydrogen ions into the matrix

The tasmanian devil, a marsupial carnivore, is facing extinction due to devil facial tumor disease (dftd) which causes bulging cancerous lumps and lesions to erupt around the face and neck — often causing enough deformation to make seeing or eating difficult. dftd has evolved into a contagious cancer, a trait that is unique among cancers. devil mating behavior involves biting around the head and neck, allowing cells from one individual — especially cells from the crumbly dftd tumors — to be transferred to the wounds or face of a new individual. this marsupial was once found across australia, but sea levels rose, isolating the tasmanian population, while the australian population went extinct. what would be an outcome of genetic isolation that is likely to have impacted the spread of dftd? a) reduced territory puts diseased individuals in greater contact with non-diseased ones. b) inbreeding results in less variation in facial features so the cancer is generally fatal. c) genetic isolation has made it difficult for scientists to develop a vaccine against dftd. d) the lack of genetic variation in the immune system of tasmanian devils minimizes resistance to the disease.
