Question

Q- In biological system, the metal ion involved in dioxygen transport besides fe is .
(1) Co
(2) Zn
(3) Mg
(4) Cu​

Answer 1

Answer:

Zn is the correct answer

Answer 2

In a biological system, the metal ion involved in dioxygen transport besides Fe is Cu.

• The majority of living things need molecular oxygen to survive.
• A protein that transports dioxygen is the essential element. The dioxygen-binding site, or so-called "active site," in each of the three chemically different carriers that have developed and are still present today, is a complex of either copper or iron.
• Copper or iron transition-metal complexes are at the heart of biological dioxygen transport.
