Published	09/24/2023	Strong reducing agents are highly {{c1::negative::positive/negative}} and strong oxidizing agents are highly {{c1::positive::positive/negative}}.&nbsp…
Published	09/24/2023	Oxygen has a {{c1::high::high/low}} reduction potential
Published	09/24/2023	NAD+ has a {{c1::low::high/low}} reduction potential which is why it is used early on in the electron transport chain.
Published	09/24/2023	Humans use {{c1::chemoorganotrophic}} metabolism, where organic compounds are used to produce energy and carbon flow.
Published	09/24/2023	Bacteria use {{c1::chemolithotrophic}} metabolism, where inorganic compounds produce energy and they take CO2 out of air to create organic compounds.&…
Published	09/24/2023	Plants (and some bacteria) use {{c1::phototrophic}} metabolism, where light is used to produce energy. Organic compounds can also be used.
Published	09/24/2023	Chemolithotrophs are mostly {{c1::autotrophic}}, obtaining carbon from CO2.
Published	09/24/2023	Reducing power for biosynthesis in chemolithotrophs comes directly from {{c1::inorganic compounds (if sufficiently low E0 )}} or from {{c2::rever…
Published	09/24/2023	Chemotrophs obtain energy from the oxidation of inorganic compounds through the {{c1::electron transport chain (like chemoorganotrophs) }}
Published	09/24/2023	{{c1::Sulfur oxidizing bacteria}} were the first to be discovered to oxidize inorganic compounds and was discovered by Sergei Winogradsky (1880s) stud…
Published	09/24/2023	Oxidation of inorganic compounds by O2 (O2 as electron acceptor) can generate sufficient energy for {{c1::ATP synthesis }}
Published	09/24/2023	Sulfur oxidizing bacteria store sulfur through a bunch of {{c1::sulfur granules}} on its surface
Published	09/24/2023	What's the Winogradsky Column?
Published	09/24/2023	How is hydrogen sulfur oxidized?
Published	09/24/2023	Sulfite is an important intermediate in the oxidation of sulfur and is oxidized by two pathways: {{c1::sulfite oxidase pathway}} and {{c1::adenosine p…
Published	09/24/2023	What relationship does bacteria have with tubeworms?
Published	09/24/2023	What are the two basic facts of life?
Published	09/24/2023	What did the original microorganism have to do to produce energy in an atmosphere with no O2 and an earth with no organic compounds?
Published	09/24/2023	What does the amount of energy released in a redox reaction depend on?
