Which of the following statements correctly differentiates between catabolic and anabolic pathways?
A: Catabolic pathways consume energy to build complex molecules, while anabolic pathways release energy by breaking down complex molecules.
B: Catabolic pathways are "downhill" avenues that release energy, whereas anabolic pathways are "uphill" avenues that consume energy.
C: Cellular respiration is an example of an anabolic pathway, while the synthesis of a protein from amino acids is a catabolic pathway.
D: Catabolic pathways involve the formation of bonds, while anabolic pathways involve the breaking of bonds.
Explanation
Catabolic pathways, also known as breakdown pathways, release energy by breaking down complex molecules and are described as 'downhill.' Anabolic pathways, or biosynthetic pathways, consume energy to build complex molecules from simpler ones and are described as 'uphill.'
