COM

Features
Read full description

COM simulates experiments with isolated mitochondria in an incubation chamber fitted with an oxygen electrode (oxygraph). Add mitochondria, substrates, ADP, inhibitors and uncouplers one after another and follow, in real time, O₂ consumption and the electrical potential of the inner membrane (Δψ). The challenge is to find out what each compound does: which ones stimulate oxygen consumption, which ones inhibit it, where each electron transport chain inhibitor acts and how uncouplers separate respiration from ATP synthesis. • 15 compounds: malate, pyruvate, α-ketoglutarate, succinate, TMPD + ascorbate, ADP + phosphate, rotenone, malonate, antimycin A, cyanide, carbon monoxide, oligomycin, 2,4-dinitrophenol and FCCP • Recording of dissolved O₂ and Δψ, with a numbered history of every addition • Several experiments side by side for comparison • Question guide for undergraduate classes and an answer table for teachers • Portuguese, English and Spanish Current version of the COM simulator, created in 1997 at the Educational Technology Laboratory (LTE), Institute of Biology, University of Campinas (Unicamp), and used in biochemistry courses ever since. Part of BIOQUÍMICA +30. Free, no ads, no sign-up and no data collection. Works offline.

Have you tried yourself to assemble the coat of the Ebola virus? I have and my results in interactive 3D virtual reality you can enjoy here for free! In addition to the ebola virus, you can explore here also the structure of the HIV (HIV=human immunodeficiency virus) virus, influenza virus, adenovirus and bacteriophage - the strange but very important virus that infects only the bacterial cells and has played a very important role in the genetics (as well as the adenovirus).
