Which Statement Could Be Used as Part of a Description

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.
