D
Protein synthesis
Verified step by step guidance
1
Understand the concept of catabolic processes: Catabolic processes involve the breakdown of complex molecules into simpler ones, releasing energy in the process.
Identify the processes listed: DNA replication, Glycolysis, Photosynthesis, and Protein synthesis.
Analyze each process: DNA replication is the synthesis of DNA, Photosynthesis is the synthesis of glucose from carbon dioxide and water, and Protein synthesis is the creation of proteins from amino acids. All these are anabolic processes, which build complex molecules.
Focus on Glycolysis: Glycolysis is the breakdown of glucose into pyruvate, releasing energy in the form of ATP. This is a classic example of a catabolic process.
Conclude that Glycolysis is the correct answer as it involves the breakdown of a complex molecule (glucose) into simpler molecules (pyruvate) with the release of energy.
