Cyanide (cn-) is a metabolic poison that inhibits the activity of complex iv. reduced complex iv must be able to bind to oxygen (o2) in a particular location on the enzyme called its "active site," in order to catalyze the reduction of o2. but cyanide binds in the same location, preventing complex iv from binding and reducing oxygen. for this reason, it’s called a "competitive inhibitor" of complex iv. which of the following would you expect to see in the mitochondria of cells exposed to cyanide, relative to cells that are not exposed to cyanide? (select two answers)decreased levels of reduced complex ivincreased levels of reduced complex i increased concentration of nad+ decreased atp productionincreased atp production

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
