Question

chemical reactions that yield energy from macronutrients rely on the participation of numerous coenzymes. match the following b vitamins to their coenzyme forms.
thiamin pyrophosphate (tpp) coenzyme a (coa) nicotinamide adenine dinucleotide phosphate (nadp)
flavin adenine dinucleotide (fad) pyridoxal phosphate (plp) flavin mononucleotide (fmn)
nicotinamide adenine dinucleotide (nad)
thiamin riboflavin niacin
pantothenic acid vitamin b - 6 reset

Explanation:

• Thiamin: Thiamin pyrophosphate (TPP) is the coenzyme form of thiamin. It plays a crucial role in carbohydrate metabolism, specifically in the decarboxylation of alpha - keto acids.
• Riboflavin: Riboflavin has two coenzyme forms, Flavin adenine dinucleotide (FAD) and Flavin mononucleotide (FMN). These coenzymes are involved in redox reactions in the electron transport chain and various metabolic pathways.
• Niacin: Niacin forms two coenzymes, Nicotinamide adenine dinucleotide (NAD) and Nicotinamide adenine dinucleotide phosphate (NADP). NAD is involved in redox reactions in catabolic pathways (e.g., glycolysis, citric acid cycle), while NADP is more prominent in anabolic pathways (e.g., fatty acid synthesis).
• Pantothenic Acid: Coenzyme A (CoA) is the coenzyme form of pantothenic acid. It is involved in acyl group transfer reactions, such as in the citric acid cycle (acetyl - CoA) and fatty acid metabolism.
• Vitamin B - 6: Pyridoxal phosphate (PLP) is the coenzyme form of vitamin B - 6. It is involved in amino acid metabolism, including transamination, decarboxylation, and racemization reactions.

Answer:

Thiamin: Thiamin pyrophosphate (TPP)
Riboflavin: Flavin adenine dinucleotide (FAD), Flavin mononucleotide (FMN)
Niacin: Nicotinamide adenine dinucleotide (NAD), Nicotinamide adenine dinucleotide phosphate (NADP)
Pantothenic Acid: Coenzyme A (CoA)
Vitamin B - 6: Pyridoxal phosphate (PLP)
