O2 is required for aerobic respiration to take place. Aerobic respiration is required to make ATP. ATP is required in a very large number of biological processes. If there is no ATP, then these processes cannot take place (almost every biological process uses ATP at some point).
The red blood cells. This is because it will increase surface area for the absorption of oxygen.
Yes, thats the lack of sleep. Agitation or loss extreme loss of appetite are a sign of killed cells.
Unlike the other cells in your body red blood cells do not have DNA or a nucleus. They do contain hemoglobin, a protein which allows your red blood cells to carry oxygen and other gases.
Red blood cells lack a nucleus and organelles, such as mitochondria, which are present in white blood cells. This allows red blood cells to have more space to carry oxygen and carbon dioxide through the bloodstream efficiently.
The red blood cells themselves do not take any action to get more oxygen, but the kidneys sense a lack of oxygen and produce more erythropoietin (hormone responsible for producing red blood cells) and this in turn increases oxygen levels
Carbon monoxide attaches to the red blood cells, and prevents them from taking on oxygen. When oxygen cannot be transported to the tissues of the body (brain, heart) they die from lack of oxygen.
Lack of Oxygen over time could cause brain damage. :\ and death.
oxygen
Infection poisioning overheating or lack of oxygen
Brain cells can only survive for 3 minutes without a supply of oxygen.
For the most part, oxygen is used to help cells generate energy from carbon sources. Some cells can use oxygen to generate toxins which are used to kill pathogens.
This is a biology question, but the answer is Prokaryotic. ------------------------------------------------------------------------------------ Red blood cells also lack a nucleus.
Iron is needed to produce haemoglobin, which is the part of the blood that carries oxygen throughout the body. A lack of haemoglobin means less oxygen available to be utilised by cells for energy
Me too quero saber
Lack of oxygen in the cells. Cellular respiration requires oxygen. Without oxygen, the cells acquire the energy they need from lactic acid fermentation. (This is the cause of muscle pain after workouts).
cellular respiration if there is enough oxygen. Lactic Acid fermentation if there is a lack of oxygen.
A heart attack occurs when blood flow to the heart is blocked, causing a lack of oxygen to the heart muscle cells. This lack of oxygen leads to cell damage and death. The damaged cells release harmful substances that can trigger inflammation and further damage surrounding cells.
