Which of the following ionic species is present in hemoglobin and responsible for transformation of oxygen ?
- A$\text{Ca}^{+2}$
- B$\text{Co}^{+3}$
- Correct answerC$\text{Fe}^{+3}$
- D$\text{Mg}^{+2}$
Solution
Hemoglobin is an iron-containing metalloprotein found in red blood cells, responsible for the transport of oxygen in the body.
The central metal ion in the heme group of hemoglobin is iron (specifically $\text{Fe}^{+2}$ in its active state). Among the given options, the iron species is the correct choice.
Answer: $\text{Fe}^{+3}$
The central metal ion in the heme group of hemoglobin is iron (specifically $\text{Fe}^{+2}$ in its active state). Among the given options, the iron species is the correct choice.
Answer: $\text{Fe}^{+3}$
Hence, the correct answer is option: 'C'.
