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

At steady state, air at 200 kpa, 325 k, and mass flow rate of 0.5 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. the inlet cross-sectional area is 6 cm2. at the duct exit, the pressure of the air is 100 kpa and the velocity is 250 m/s. neglecting potential energy effects and modeling air as an 1.008 kj/kg k, determine ideal gas with constant cp = (a) the velocity of the air at the inlet, in m/s. (b) the temperature of the air at the exit, in k. (c) the exit cross-sectional area, in cm2
