Understand the concept of anabolic pathways: Anabolic pathways are those that build complex molecules from simpler ones, requiring energy input. They are the opposite of catabolic pathways, which break down complex molecules into simpler ones, releasing energy.
Analyze the given options: Fermentation, Glycolysis, Photosynthesis, and Beta-oxidation. Determine which of these processes involve the synthesis of complex molecules.
Consider Photosynthesis: This process involves the conversion of carbon dioxide and water into glucose and oxygen, using energy from sunlight. It is a classic example of an anabolic pathway because it builds glucose, a complex molecule, from simpler substances.
Evaluate the other options: Fermentation and Glycolysis are catabolic processes that break down glucose to release energy. Beta-oxidation is also a catabolic process that breaks down fatty acids to generate acetyl-CoA and energy.
Conclude that Photosynthesis is the correct example of an anabolic pathway, as it involves the synthesis of glucose, a complex molecule, from simpler molecules, with the input of energy from sunlight.
