Amphibians usually have lungs but they can also absorb oxygen through their moist skin. Their body temperature also varies according to their surroundings. Amphibians also reproduce by external fertilisation and lag eggs.
All redox chemistry of the pyridine nucleotide coenzymes takes place at the 4-position of the pyridine ring.
<h3>What are pyridine nucleotide coenzymes?</h3>
The pyridine nucleotide coenzymes are specific coenzymes responsible for oxide reduction reactions during cellular respiration.
The pyridine nucleotide coenzymes include nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP) and they function by accepting/donating electrons during chemical reactions of the cellular respiration.
In conclusion, all redox chemistry of the pyridine nucleotide coenzymes takes place at the 4-position of the pyridine ring.
