if your brain has been starved of oxegen for 12 minutes due to a heart attack what can happen

Explain why DNA replication must occur before mitosis starts?
DNA replication mus occur before mitosis starts. Mitosis is another word for cell division and so there must be two copies of DNA for each cell at the end stage.
What is an ischemic cell?
an ischemic cell is a cell that is deprived of o2 and there forth has switched from aerobic metabolism to anaerobic . eventually this will cause the cell to burst because the ATP production is not sufficient to maintain the cell environment
How many layers of cells does oxygen diffuse through before it reaches a red blood cell?
millions of cells
Name the substance in red blood cells that combines with oxygen?
The protein "Hemoglobin" is responsible for the red color. Each hemoglobin molecule can bind up to 4 oxygen atoms. When fully loaded with oxygen atoms the protein takes on a more bright red color. When deprived of oxygen the protein takes on a darker red/blue color.
Which is the smallest organisms that lack cell wall and it is smallest living cell which can survive without oxygen?
Which is the smallest living cell which lacks cell wall and can survive without oxygen
Why is the lack if of oxygen in the brain cell able to cause death?
Cells anywhere in the body (especially in the brain) will die if deprived of oxygen enriched blood for long.
When a cell is deprived of oxygen its lysosomes tend to burst and release their contents into a cell what happens to the cell?
Since lysosomes produce digestive enzymes, the cell will literally start to eat itself. Lysosomes even do this on purpose sometimes to recycle old cells. That's why the lysosomes are nicknamed suicide sacks.
What is happening to the genetic material just before a cell leaves interphase and starts prophase of cell division?
replicating
What role did diffusion play in the changes you observed?
Before diffusion there is a higher concentration of oxygen molecules outside the cell than inside the cell. After diffusion the concentration of oxygen molecules is the same outside and inside the cell.
Explain why DNA replication must occur before mitosis starts?
DNA replication mus occur before mitosis starts. Mitosis is another word for cell division and so there must be two copies of DNA for each cell at the end stage.
What if a cell receives no oxygen or food?
The cell would die. A cell is just like you. A cell can not live with out oxygen or food!
In many this process follows mitosis?
The process that follows mitosis in cells is cytokinesis. Cytokinesis is the process of the cell dividing the daughter cell from the original cell before the process starts again.
Why is the oxygen important to blood and to the cell?
because oxygen brings food to the cell
What is an ischemic cell?
an ischemic cell is a cell that is deprived of o2 and there forth has switched from aerobic metabolism to anaerobic . eventually this will cause the cell to burst because the ATP production is not sufficient to maintain the cell environment
What two gases are exchange in the cell?
oxygen and carbon dioxide. oxygen is delivered by the blood into the cell and oxygen from the cell is is given to the blood in exchange to be expelled by the lungs.
In many cells this this process follows mitosis?
The process that follows mitosis in cells is cytokinesis. Cytokinesis is the process of the cell dividing the daughter cell from the original cell before the process starts again.
How many layers of cells does oxygen diffuse through before it reaches a red blood cell?
millions of cells
