Plant Structure The mitochondria were known in the nineteenth century to be osmotically active on the basis of evidence that mitochondria are surrounded by a semi permeable membrane the mitochondrial matrix is hypertonic to the cellular cytoplasm the mitochondrial matrix is hypotonic to the cellular cytoplasm mitochondria were derived from a symbiotic bacterium mitochondria are surrounded by a semi permeable membrane the mitochondrial matrix is hypertonic to the cellular cytoplasm the mitochondrial matrix is hypotonic to the cellular cytoplasm mitochondria were derived from a symbiotic bacterium ANSWER DOWNLOAD EXAMIANS APP
Plant Structure Why do some redox reactions in cells result in the transfer of electrons from a reductant with a higher standard redox potential to an oxidant with a lower standard redox potential? Redox potentials are defined under standard conditions, and cellular conditions are typically not standard conditions Electrons always go from reductants with high redox potentials to oxidants with low redox potentials None of these The rules governing oxidation and reduction apply only in vitro, and not in vivo Redox potentials are defined under standard conditions, and cellular conditions are typically not standard conditions Electrons always go from reductants with high redox potentials to oxidants with low redox potentials None of these The rules governing oxidation and reduction apply only in vitro, and not in vivo ANSWER DOWNLOAD EXAMIANS APP
