In which cell is the respiratory pigment haemoglobin found in humans?
Show answer & explanation
Correct answer: A
Explanation
Red Blood Cells (RBCs) -
In humans, the respiratory pigment hemoglobin is found primarily inside red blood cells (erythrocytes).
Function: Hemoglobin binds oxygen (O2) from the lungs and transports it to all body tissues. It also helps bring carbon dioxide (CO2) back to the lungs. Structure: It is an iron-containing protein. The presence of iron is what gives blood its red appearance.
Feature: Red blood cells lack a nucleus, allowing for more hemoglobin and oxygen.
