Expert Solution
Step 1: Introduction
A heme complex is a critical molecular structure found in various biological molecules, such as hemoglobin and cytochromes. It consists of a central iron atom bound to a flat, organic molecule called a porphyrin ring. This arrangement allows heme complexes to play vital roles in transporting oxygen, aiding in electron transfer reactions, and serving as catalytic centers in enzymes. The iron atom within the heme complex can change its oxidation state, making it versatile in facilitating various biochemical processes essential for life.
