Which of the following statements about metabolism is correct?

Question

Quizplus · Accepted Answer

Metabolism refers to all the chemical reactions that take place within an organism. These include catabolic reactions (breaking down of molecules to release energy) and anabolic reactions (building up of molecules requiring energy). The sum total of these reactions is what makes up metabolism. Option B is incorrect because anabolic reactions require energy input, they do not produce energy. Option C is also incorrect because metabolic pathways can also be linear, branched or convergent/divergent. Option D is incorrect because the process of polysaccharide digestion is a catabolic process, where large carbohydrate molecules are broken down into smaller subunits, releasing energy.
