What percentage of energy released by aerobic respiration of glucose is captured by ATP?

Anaerobic respiration metabolism regenerates the ______________ required for glycolysis.

A total of ______________ molecules of ATP are produced by glycolysis.

Each turn of the Krebs cycle directly produces ______________ molecule(s) of ATP.

Beta-oxidation of an 18 carbon fatty acid will yield _____ acetyl CoA molecules.

Which amino acid serves as a channel through which other amino acids can form keto-acids?

Ketone bodies are produced by

One glucose would generate ______________ NADH molecules via the Krebs cycle.

The Cori cycle converts ______________ to pyruvic acid.

The Cori cycle involves formation of glucose made by gluconeogenesis in the liver from lactic acid produced by fermentation in skeletal muscles.

Skeletal muscle contains glucose 6-phosphatase to produce free glucose from glucose 6-phosphate.

Glycolysis would be inhibited by
