I. (noun)
Sense 1
Meaning:
English biochemist (born in Germany) who discovered the Krebs cycle (1900-1981)
Synonyms:
Hans Adolf Krebs; Krebs; Sir Hans Adolf Krebs
Classified under:
Instance hypernyms:
biochemist (someone with special training in biochemistry)
Context examples:
The transfer of the amino group from aspartate to alpha-ketobutyrate creates oxaloacetate, a Krebs cycle intermediate.
(Feeding Amino Groups into the Urea Cycle, NCI Thesaurus/BIOCARTA)
If oxygen is absent, electron transport and the Krebs cycle rapidly halt, leaving glycolysis and fermentation as the main means of energy production.
(Electron Transport Pathway, NCI Thesaurus/BIOCARTA)
The acetyl-CoA generated in beta-oxidation enters the Krebs cycle, where it is further oxidized to CO2, producing more reduced energy carriers, NADH and FADH2 (See Krebs cycle pathway).
(Beta-Oxidation of Fatty Acids Pathway, NCI Thesaurus/BIOCARTA)
During aerobic exercise, the rapid consumption of ATP leads to use of the proton gradient to make more ATP, increased electron transport to regenerate the proton gradient, increased oxygen consumption, and increased activity of the Krebs cycle and glycolysis to supply high energy electrons to drive electron transport.
(Electron Transport Pathway, NCI Thesaurus/BIOCARTA)
These carriers produced in the Krebs cycle, along with those produced directly in beta-oxidation, transfer their energy to the electron transport chain where they drive the creation of the proton gradient that supports mitochondrial ATP production.
