Which of the following is true for anabolic pathways?
A
They occur only in animal cells.
B
They are involved in the breakdown of glucose during cellular respiration.
C
They consume energy to build complex molecules from simpler ones.
D
They release energy by breaking down complex molecules.
Verified step by step guidance1
Understand the definition of anabolic pathways: Anabolic pathways are metabolic processes that build complex molecules from simpler ones, requiring an input of energy.
Differentiate between anabolic and catabolic pathways: Anabolic pathways consume energy to synthesize complex molecules, whereas catabolic pathways release energy by breaking down complex molecules.
Analyze the options given: The first option states that anabolic pathways occur only in animal cells, which is incorrect as they occur in all living cells. The second option describes a process involved in catabolic pathways, specifically cellular respiration, which is not related to anabolic pathways.
Evaluate the third option: It states that anabolic pathways consume energy to build complex molecules from simpler ones, which aligns with the definition of anabolic pathways.
Consider the fourth option: It describes the release of energy by breaking down complex molecules, which is characteristic of catabolic pathways, not anabolic pathways.
