Here are the essential concepts you must grasp in order to answer the question correctly.
Coenzymes
Coenzymes are organic molecules that assist enzymes in catalyzing reactions. They often act as carriers for chemical groups or electrons during metabolic processes. In the context of biochemical reactions, coenzymes are crucial for facilitating the transfer of atoms or functional groups, thereby enhancing the efficiency of enzymatic activity.

Hydrogenation
Hydrogenation is a chemical reaction that involves the addition of hydrogen (H2) to a carbon–carbon double bond, converting it into a single bond. This process is significant in organic chemistry and biochemistry, as it alters the saturation of organic compounds, impacting their reactivity and stability. Understanding hydrogenation is essential for grasping how certain coenzymes function in metabolic pathways.

NADH
NADH (Nicotinamide adenine dinucleotide) is a key coenzyme in cellular metabolism that plays a vital role in redox reactions. It acts as an electron carrier, picking up hydrogen ions and electrons during metabolic processes, particularly in the conversion of substrates in glycolysis and the citric acid cycle. In the context of hydrogenation, NADH is often involved in the reduction of double bonds, making it essential for understanding the biochemical pathways that involve these reactions.
