Concept explainers
(a)
Interpretation:
The metabolic products formed from pyruvate in anaerobic conditions in the body need to be determined.
Concept Introduction:
In anaerobic conditions, there is no requirement of oxygen. Anaerobic condition is fifteen times less effective than aerobic condition.
(b)
Interpretation:
The metabolic products formed from pyruvate in anaerobic conditions in yeast needs to be determined.
Concept Introduction:
In anaerobic conditions, there is no requirement of oxygen. Anaerobic condition is fifteen times less effective than aerobic condition.
(c)
Interpretation:
The metabolic products formed from pyruvate in aerobic conditions need to be determined.
Concept Introduction:
In anaerobic conditions, there is a requirement of oxygen.

- The oxidation of 1 mol of glucose supplies enough meta-bolic energy to form 36 mol of ATP. Oxidation of 1 mol of a typ-ical dietary fat like tristearin (C₅₇H₁₁₆O₆) yields enough energyto form 458 mol of ATP. (a) How many molecules of ATP canform per gram of glucose? (b) Per gram of tristearin?arrow_forwardwhat is the definition of energy from a metabolic perspective?arrow_forwardHow much energy is released as ATP from the complete oxidation of stearic acid (CH3(CH2)16COOH)?arrow_forward
- Glucose is the preferred energy source of the brain, Why?arrow_forwardDescribeenergy consumed vs released in reactions. Differentiate between endergonic vs exergonic reactions, anabolism vs catabolism, and coupled reactions.arrow_forwardWhat key metabolic intermediate is formed from the catabolism of all three major classes of foods: carbohydrates, lipids, and proteins?arrow_forward
- Trypanosomes living in the bloodstream obtain all their free energy from glycolysis. They take up glucose from the host’s blood and excrete pyruvate as a waste product. In this part of their life cycle, trypanosomes do not carry out any oxidative phosphorylation, but they do use another oxygen-dependent pathway, which is absent in mammals, to oxidize NADH. Would this pathway be necessary if the trypanosome excreted lactate rather than pyruvate? Explain.arrow_forwardIn the pathways of cell metabolism, 1) glycolysis does NOT occur in the mitochondria, AND 2) the proton gradient in oxidative phosphorylation occurs through an ACTIVE transport process. True Falsearrow_forwardWhich metabolic pathway is directly responsible for the production of the most ATP molecules?arrow_forward
