Multiple Choice

How does DNA influence the synthesis of lipids, carbohydrates, and steroids in a cell?

By directly converting DNA sequences into lipid, carbohydrate, and steroid molecules

By serving as a structural component of these molecules

By encoding enzymes that catalyze the biosynthetic pathways for these molecules

By acting as a cofactor in the chemical reactions that produce these molecules

Verified step by step guidance

Understand the role of DNA in cellular processes: DNA contains the genetic instructions for synthesizing proteins, including enzymes, which are crucial for catalyzing biochemical reactions.

Recognize that DNA does not directly convert into lipids, carbohydrates, or steroids. Instead, it encodes the information to produce enzymes that facilitate their synthesis.

Learn that enzymes are specialized proteins encoded by genes in DNA. These enzymes catalyze specific steps in biosynthetic pathways for lipids, carbohydrates, and steroids.

Explore examples of biosynthetic pathways: For instance, enzymes encoded by DNA are involved in fatty acid synthesis (lipids), glycolysis and gluconeogenesis (carbohydrates), and steroidogenesis (steroids).

Conclude that DNA indirectly influences the synthesis of these molecules by encoding the enzymes required for their production, rather than serving as a structural component or acting as a cofactor in the reactions.
