Which Statement Could Be Used as Part of a Description

question 215

Multiple Choice

Which statement could be used as part of a description of how carbohydrate, lipid, and protein are linked through catabolic and anabolic pathways?

• A) Glycolysis and fermentation only partially oxidize glucose, while the citric acid cycle and oxidative phosphorylation allow for full oxidation of glucose and transfer of its free energy to ATP.
• B) Metabolic pathways for lipids, proteins, and carbohydrates all share the same characteristic, in that they represent a series of separate chemical reactions that together accomplish a complex chemical transformation.
• C) Metabolic pathways are compartmentalized in the cell, which allows physical boundaries to organize the large numbers of metabolic interconversions taking place at any one time in a cell.
• D) Glycolysis and the citric acid cycle occupy a central position in cell metabolism, connecting to lipid, protein, and carbohydrate breakdown and synthesis through small molecule intermediates.
• E) Metabolism is a cyclical process of energy conversion in which chemical energy is harvested from nutrients in catabolic reactions and used to synthesize new molecules in anabolic reactions.
