Answer:
1. The pathway of a red blood cell from the right ventricle to the brain is:
<em>Right ventricle → pulmonary arteries → lungs → pulmonary veins → left atrium → left ventricle → artery aorta → arterial vessels → brain
.</em>
2. The substance that forms hemoglobin in red blood cells when it passes through the lungs is oxyhemoglobin.
Explanation:
Red blood cells are structures present in the blood, whose function is to transport oxygen (O₂) and carbon dioxide (CO₂). This process requires travel throughout the body, through the blood vessels, and gas exchange at the pulmonary and tissue level.
1. A red blood cell in the right ventricle contains carbon dioxide and must pass to the lungs to be oxygenated. The route it takes from there includes Right ventricle (minor circulation) → pulmonary arteries → lungs → pulmonary veins → left atrium → left ventricle → (joining the major circulation) artery aorta → arterial vessels → brain
.
2. The red blood cell or erythrocyte contains a molecule, called hemoglobin, which has an iron core that allows it to bind to O₂ and CO₂ in order to transport them. The affinity for one molecule or another depends on the presence of a certain gas in a certain place.
When the red blood cell passes through the lungs, the concentration of O₂ is higher than CO₂, so the latter is released and O₂ binds to hemoglobin, a conjugation that is called oxyhemoglobin.
Answer:
Centrioles are located near the nucleus and help organize cell division.
Answer:
The ATP molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. In this form, energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.
In a process called cellular respiration, chemical energy in food is converted into chemical energy that the cell can use, and stores it in molecules of ATP. ... When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy stored in the bond that the cell can use to do work.
