WebThis assay measures the reduction of cytochrome c by NADPH-cytochrome c reductase in the presence of NADPH. The absorption spectrum of cytochrome c changes with its oxidation/reduction state. Upon reduction a sharp absorption peak is observed at 550 nm. The reduction ofcytochrome c is monitored by the increase of cytochrome c absorbance … WebNov 14, 2024 · When people ingest cyanide ion, the cyanide binds strongly to the enzyme that transfers electrons from cytochrome c to oxygen. This blocks the enzyme from functioning. Why does this cause death so quickly? Cyanide poisoning victims often feel like they are suffocating and breathe deeply and rapidly before death. Why do you think they …

Cyanide is toxic to clover plants because they use cytochrome c oxidase for ATP synthesis in the chloroplasts. Cyanide is nontoxic to clover plants because they carry out electron transport in chloroplasts rather than in mitochondria. WebControl of Respiration by Cytochrome c Oxidase in Intact Cells.
