Answer:
b. reducing molecules
Explanation:
Nicotinamide adenine dinucleotide (abbreviated NAD +, and also called diphosphopyridine nucleotide and Coenzyme I), is a coenzyme found in all living cells. The compound is a dinucleotide, as it consists of two nucleotides linked through their phosphate groups with a nucleotide that contains an adenosine ring and the other that contains nicotinamide.
In metabolism, NAD + participates in redox reactions (oxidoreduction), carrying electrons from one reaction to another.
Coenzyme, therefore, is found in two forms in cells: NAD + and NADH. NAD +, which is an oxidizing agent, accepts electrons from other molecules and becomes reduced, forming NADH, which can then be used as a reducing agent to donate electrons. These electron transfer reactions are the main function of NAD +. However, it is also used in other cellular processes, especially as a substrate for enzymes that add or remove chemical groups of proteins, in post-translational modifications. Due to the importance of these functions, the enzymes involved in the metabolism of NAD + are targets for drug discovery.

Dna is shaped as a double helix and has weak hydrogen bonds. They contain complementary base pairs (adenine and thymine) and (guanine and cytosine).
Hope this helps.
Answer:
In the boreal forest the ground thaws more and does not have a permafrost layer. This allows trees to take root. Compose an argument for categorizing mountains and polar regions as terrestrial biomes. Mountains and polar regions have these characteristics and provide land on which certain plants and animals can live.
