$\%$ You have determined that Dr$.$ Sooss was in possession of antimycis A$!$ You have now determined which inhibitor that each scientist was stadying. You return to the hospital, where you meet the physicians working on De$.$ Tamm's case. He is still unconscions, bot they have some lab results for yoe. Aer you ready?

Dr$.$ Tamm has no accumalation of NADH or succinate. In fact, both levels are low. Additionally, all the intermodiates of be ETC that the doctors tested are in a mixtere of reduced and otidized states. However, they do note that there is sliphtly more of the oxidiued form of every comples and intermediate than would be expected in a heathy person.

Which ETC inhibitor could have caused these rewults, and who tried to kill De$.$ Tamm?

Rotenone caused these revalts, so De$.$ Stralaje is the attempted manderer!

KCN caused these rewalis, $50$ DE $.$ Hoo is the atiempted manderer!

Astimycin A caused these revults, se DV$.$ Sooss is the attempted menderer!

A combination of all theee iehibitors caused these resels, se all three sciendist collaboraind to mander Dr$.$ Tamm!

Nowes of the three inhibitors could have caused there resula, so Dr$.$ Trme's condition is not due lo attempted homicide after all!
