 Context examples 

When ATP is needed, this acetyl-CoA can enter the Krebs cycle to drive oxidative phosphorylation.

(Acetyl Group Shuttle Pathway, NCI Thesaurus/BIOCARTA)

This NADH comes primarily from the Krebs cycle in the mitochondrial matrix and is therefore directly accessible to electron transport.

(Malate-Aspartate Shuttle Pathway, NCI Thesaurus/BIOCARTA)

Excess amino acids in the body can be used as a source of energy, with their carbon skeleton converted to metabolic intermediates such as acetyl-CoA or intermediates in the Krebs cycle.

(Feeding Amino Groups into the Urea Cycle, NCI Thesaurus/BIOCARTA)

About 350 enzymes involved in glycolysis and the Krebs cycle, formation of cyclic-AMP and ATP, cellular signal transduction and protein and nucleic acid synthesis are dependent on magnesium.

(Magnesium Acetate, NCI Thesaurus)

Glycolysis and the Krebs cycle are also closely linked to the energy needs of the cell.

(Electron Transport Pathway, NCI Thesaurus/BIOCARTA)

The citrate cycle (TCA cycle, Krebs cycle) is an important aerobic pathway for the final steps of the oxidation of carbohydrates and fatty acids.

(Citrate Cycle (TCA Cycle) Pathway, NCI Thesaurus/KEGG)

The propionyl-CoA produced in this manner is converted to succinyl-CoA that then enters the Krebs cycle.

(Beta-Oxidation of Fatty Acids Pathway, NCI Thesaurus/BIOCARTA)

The oxidation of fatty acids is an important source of energy for ATP production in mitochondria through the entry of acetyl-CoA into the Krebs cycle.

(Mitochondrial Carnitine Palmitoyltransferase Pathway, NCI Thesaurus/BIOCARTA)

This gene plays a role in the Krebs cycle.

(FH Gene, NCI Thesaurus)

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).
