Acute porphyria is a disorder that affects how your body makes red blood cells (RBC). Your body needs a chemical called porphyrin to make heme, a part of RBC that carries oxygen. Porphyria prevents your body from creating enough enzymes to control the process, and porphyrin builds up. High...
When you heat your meat up to higher temperatures above 170 degrees, hemichrome levels rise further, and the myoglobin turns intodenatured metmyoglobin. This is what gives well-done meat its dark brown appearance. While these color changes are the result of temperature increases, it must be sai...
Each hemoglobin molecule consists of globin (two alpha and two beta polypeptide chains) and a heme group attached to each polypeptide chain. Each hemoglobin can bind up to four oxygen molecules.Answer and Explanation: Macrophages in the spleen, liver, or red bone marrow phagocytose damaged or ...
In the human body, what makes blood a viscous fluid? With aging, the pH of blood ___. a) increases b) decreases c) remains the same What is the first change in arterial blood gases with diarrhea? a. increased bicarbonate ion b. decreased bicarbonate ion c. increased carbonic acid ...
Question: What color is your blood? What Determines the Color of Blood? The color of blood is mostly determined by a protein found in blood called hemoglobin. Hemoglobin is the protein responsible for distributing oxygen to the blood to be carried around the body. ...
Hemoglobin is made up offour proteinsorganized around the iron-carrying heme group. These proteins are called globins, and each hemoglobin molecule has two alpha and two beta-globins. Sickle cell disease changes adult beta-globin. Instead of two alpha and two healthy beta chains, sickle cell ...
What if we look at fertility as a state of being rather than ones ability to reproduce. Could shifting our thoughts about what it means to be fertile enhance our lives?
This illness results when the bone marrow makes insufficient blood for the body. The condition results in lower than expected levels of RBCs, white blood cells (WBCs), and platelets. It may either be inherited or acquired. Acquired cases may come on suddenly or develop slowly. There are seve...
meats, and seafood). Since the body doesn't absorb non-heme iron as well as heme iron, plant-based eaters need to consume nearly twice as much iron to get their fill, per the NIH. And luckily, these crunchy hemp hearts can help herbivores easily amp up their iron intake, says Gans....
