Concept explainers
(a)
Interpretation: To determine the number of
Concept introduction: Glucose is converted to pyruvate by glycolysis
The Cori cycle is named after its discoverers, Gerty Radnitz Cori, and Carl Cori.
The molecule that contains six carbon atoms is termed as a
(b)
Interpretation: To determine the number of molecules involved in gluconeogenesis.
Concept introduction: Gluconeogenesis is an eleven-step pathway in which glucose is produced from non-carbohydrate substances. An overview of gluconeogenesis is as follows:
The molecule that contains six carbon atoms is termed as a
(c)
Interpretation: To determine the number of
Concept introduction: In the glycolysis metabolic pathway, a glucose molecule breaks down into two pyruvate molecules. Two ATP molecules and NADH reduced coenzymes are produced in the glycolysis pathway.
The molecule that contains six carbon atoms is termed as a
(d)
Interpretation: To determine the number of
Concept introduction: Lactate dehydrogenase enzymes convert pyruvate to lactate under anaerobic conditions in the human body. This anaerobic reduction of pyruvate to form lactate by enzymes is called lactate fermentation. The overall reaction equation for the conversion of pyruvate to lactate is as follows:
The molecule that contains six carbon atoms is termed as a

- Which nutrient provides energy in its most concentrated form?arrow_forwardWhat is the substrate for pyruvate dehydrogenase? a. pyruvic acid b. water c. hydrogen d. coenzyme Aarrow_forwardIn the electron transport chain, the hydrogen ions enter the inner compartment of mitochondria through special channels formed by A. ATP synthase. B. coenzyme A. C. acetyl CoA. D. oxygen.arrow_forward
- Fatty acids and triglycerides are an important source of nutrition and a dense form of stored energy. Digestion of fats yields more energy per gram than digestion of carbohydrates. Each turn on the B-oxidation spiral results in the formation of a new acetyl COA molecule. This molecule can then be used to generate more energy in A) fatty acid synthesis B) ketolysis C) glycolysis D) tricarboxylic acid cycle E) oxidative phosphorylationarrow_forwardWhich enzyme is involved in the conversion of phosphoenolpyruvate to pyruvate? a. enolase b. ketolase c. pyruvate kinase d. pyruvate oxidasearrow_forwardBased on the names of the enzymes participating in glycolysis, what would be the name of the enzyme catalyzing the activation of glycerol? A. Glycerol kinase B. Glycerol dehydrogenase C. Glycerol hydratase D. Glycerasearrow_forward
