Catalyzing peptide bond formation in ribosomes

Verified step by step guidance

Understand the role of riboflavin in biochemical processes: Riboflavin (vitamin B2) is a water-soluble vitamin that primarily functions as a precursor for the coenzymes flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD). These coenzymes are essential for redox reactions in cellular metabolism.

Analyze the first option: 'Acting as a coenzyme in redox reactions.' Riboflavin-derived coenzymes (FMN and FAD) are directly involved in redox reactions, such as those in the electron transport chain and oxidative phosphorylation. This option aligns with the known biochemical role of riboflavin.

Evaluate the second option: 'Facilitating the storage of triglycerides.' Riboflavin does not play a direct role in triglyceride storage. This process is primarily regulated by enzymes and hormones like insulin, not by riboflavin or its coenzymes.

Assess the third option: 'Serving as a direct source of genetic information.' Riboflavin is not involved in genetic information storage or transmission. DNA and RNA are the molecules responsible for genetic information, not vitamins like riboflavin.

Consider the fourth option: 'Catalyzing peptide bond formation in ribosomes.' Peptide bond formation is catalyzed by the ribosomal RNA (rRNA) within the ribosome, not by riboflavin or its coenzymes. This option is incorrect.
