In the lab, metabolic poisons can be used to study ATP synthesis and oxygen consumption. Many of these poisons have – or have had – other uses, from diet aids to animal poisons to antibiotics.
Poison Action
oligomycin binds to F0 and blocks the proton channel
carbon monoxide inhibits cytochrome oxidase by reacting with heme a3
trifluorocarbonylcyanide-
phenylhydrazone (FCCP) increases membrane proton permeability
antimycin prevents electron flow between cytochrome b and
cytochrome c
bongkrekic acid binds to inward‑facing site of ATP‑ADP translocase
Classify the metabolic poisons as electron transport inhibitors, uncoupling agents, ATP synthase inhibitors, or transport inhibitors.

Even though the ostrich is a flightless bird, ostriches still possess wings that stretch approximately two meters across when fully extended. scientists speculate that when dinosaurs became extinct, some of the birds that lived during that time became land dwellers since they were able to consume the food that the dinosaurs once ate. over time, these species grew larger and heavier. eventually, the ostrich species became too big to fly. the wings found on ostriches are known as a. analogous structures. b. homologous structures. c. vestigial structures. d. symmetrical structures.
