How many atoms are in 155g of calcium? How many oxygen molecules can hemoglobin carry? The atomic number of oxygen is 8. What is the mass number of an oxygen atom with 7 neutrons? The atomic number of oxygen is 8. What is the mass number of a oxygen atom with 7 neutrons?
Each molecule of hemoglobin contains four iron atoms, and each iron atom can bind with one molecule of oxygen (which contains two oxygen atoms, called O2) for a total of four oxygen molecules (4 * O2) or eight atoms of oxygen for each molecule of hemoglobin. The iron in hemoglobin gives...
During respiration, after the oxygen enters the lung, explain how the oxygen molecules move from air into blood. Also, list the type of cells and molecules involved in this process. Explain the innervations of the respiratory system...
once oxygen can be obtained through breathing. However, in sickle cell disease and beta thalassemia, people have faulty versions of the adult gene. Casgevy reverses the switch to adult hemoglobin so that patients
They help break down nutrients into smaller, more easily absorbed molecules. For many, taking these supplements can help relieve bloating by minimizing the fermentation that can occur when nutrients aren’t fully digested. This fermentation process can draw in gas, leading to bloat and discomfort. ...
Draw water up to the surface from lower layers:Lotions that do this arehumectants. They have a special chemical structure that creates bonds with water molecules. This lets them pull water molecules to the skin's surface like a magnet. ...
DNA molecules carry genetic instructions for our cells. Most of the time that DNA is tightly coiled缠绕 around proteins. A new study shows that the coiled DNA acts much like the string on a yo-yo. And that’s good, because by being rolled up, each cell can store a lot of instructions...
Each molecule of hemoglobin contains four iron atoms, and each iron atom can bind with one molecule of oxygen (which contains two oxygen atoms, called O2) for a total of four oxygen molecules (4 * O2) or eight atoms of oxygen for each molecule of hemoglobin. The iron in hemoglobin gives...
O2 is transported from the lungs to the bodies tissues by binding to the iron atoms of haemoglobin in red blood cells, changing their colour from blue to red. Haemoglobin is a tetrameric molecule that can sequentially bind four oxyg...
During blood cell formation, why is the nucleus ejected from the normoblast? 1. To increase the space for hemoglobin 2. To increase cell surface area 3. To decrease cell volume 4. To increase space for carrying carbon dioxide molecules. ...
