NEET BIOLOGY

Detailed explanation-1: -Iron from food comes in two forms: heme and non-heme. Heme is found only in animal flesh like meat, poultry, and seafood. Non-heme iron is found in plant foods like whole grains, nuts, seeds, legumes, and leafy greens.

Detailed explanation-2: -It’s common for people to think that iron and haemoglobin are the same thing, but they’re actually quite different. Iron is a component of haemoglobin and is also found in other parts of the body. It’s possible to have a normal haemoglobin level but be low in iron.

Detailed explanation-3: -Red blood cells use a molecule called hemoglobin to transport oxygen around the body. To make hemoglobin, cells require iron to build a component called heme. If an individual does not get enough iron in their diet, the body cannot produce enough red blood cells, or the cells lack hemoglobin.

Detailed explanation-4: -Heme is an iron-containing molecule that is important for many biological processes. Heme combines with globin proteins to form hemoglobin, which carries oxygen in red blood cells from the lungs to the rest of the body.
