Magnesium is central part of:
Correct answer: A. Porphyrin ring
- A. Porphyrin ring
- B. Phytol tail
- C. Pyrrole ring
- D. Hydrophobic part
Explanation
In porphyrin rings, the central atom is typically a metal ion, and one common metal ion found in porphyrin rings is magnesium (Mg).Explanation is given below.In porphyrin rings, the central atom is typically a metal ion, and one common metal ion found in porphyrin rings is magnesium (Mg).tral atom is typically a metal ion, and one common metal ion found in porphyrin rings is magnesium (Mg).The porphyrin ring structure consists of four pyrrole units connected together by methine bridges. The central magnesium ion coordinates with the four nitrogen atoms present in the pyrrole rings, forming coordination bonds. This coordination complex is often referred to as a metalloporphyrin.The porphyrin ring structure consists of four pyrrole units connected together by methine bridges.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
