Final answer:
Transition metals like iron, copper, and silver play essential roles in biological systems, facilitating various biochemical processes such as oxygen transport and energy production.
Step-by-step explanation:
The speciation of metal/inorganic elements carries significant importance in biological systems. Transition metals, such as iron, copper, and silver, play crucial roles in various biochemical processes. For example, iron is a vital component of hemoglobin, the protein responsible for oxygen transport in red blood cells.
Copper is crucial for enzymes involved in energy production, while silver possesses antimicrobial properties. These elements facilitate electron transfer reactions, small molecule reactions, and catalytic processes critical for life.
