What do we call the chemical that cells need to work and reproduce?
Cells need many chemicals, but perhaps you are thinking of DNA.
Do you need to fast before a cbc lab test?
No. It is not necessary to fast for a CBC. Generally tests like Lipid profiles and Glucose testing are ones that will require you to fast. CBC is a test that deals with your blood cells.

What Substance used in all cells to release energy?
I really need help to answer this question because the other answer is not right.Also people need to learn to not put wrong answers on because it is reallly annoying.And finally i am doing homework and am really boreddd :(
Why do you need oxgen?
Oxygen is needed by every living cell in your body in order to release the energy needed for life through the process of cellular respiration (ie. "burning" the calories found in glucose, or blood sugar). Without oxygen, cells cannot get energy and they will die.
What organ does not need insulin?
Every organ is made up of many cells and each of these cells need glucose for the provision of energy. Glucose molecules cannot enter the cells however unless they are each joined with a molecule of insulin. This is why the blood glucose is raised with diabetes. No insulin, then no glucose entering the cells. Hope this helps.
What two organs dont need insulin to breakdown down glucose?
first of all, insulin dosent break down glucose, it just facilitates its entry into cells secondly the answer you are probably looking for is: in the brain and in the eyes, glucose can enter both sites without need for insulin but also know that exercise causes the muscles to become insulin independent as well
Is glucose found in urine?
If your body doesn't take the glucose from the blood into the cells by using insulin, the glucose will be lost in the urine. Since you need glucose for your cells to survive, you need the insulin. If no insulin is produced or too little is, you are a diabetic and have to take some form of artificial insulin.
What hormone is required for the normal use of glucose in the body?
Insulin is the hormone that allows cells to take up glucose. Insulin is synthesised and released from the beta cells in the islets of langerhans of the pancreas. Its release is stimulated by high blood glucose levels.
Why would a doctor advise a drip of glucose than oil or fat when oil or fat contains more energy than glucose?
Cells require glucose. Glucose is delivered faster to the cells than fat or oil. In diabetes, the person may need administration of insulin along with glucose. Insulin is like a key to "unlock" the cell's door, to transport glucose into the cell. Diabetics do not produce enough insulin, so they need pills or injections of insulin.
Do insulin change cell permeability to glucose?
There is no mention of cell permeability in the Wikipedia article. What insulin does is increase the transport of glucose within cells. As the cells use insulin more, the blood sugar decreases. Certain cell types need insulin to get proper glucose levels, so that is why someone with diabetes might be hungry all the time and still losing weight. So cells can starve even when the blood glucose levels are high.The insulin receptors regulate the number and operation of transporter proteins. Insulin tells fat cells to store glucose. It also tells the pancreas to not release glucagon. Glucgon causes the liver to convert stored glycogen to glucose. So insulin helps prevent that process.
How does insulin effect blood sugar and how does this relate to type 1 and type 2 diabetes?
Insulin is the chemical released from the pancreas (in non-Diabetics) to lower blood sugar whenever we eat. Type 1 Diabetics are insulin dependent (need to inject themselves with insulin to stay at a healthy blood sugar level) and Type 2 Diabetics who don't necessarily look after themselves well may need to become insulin dependent.
What foods lower my blood sugar?
Lowering your blood sugar is important to avoid pre-diabetes, diabetes, insulin resistance and overweight issues. Lowering your blood sugar naturally keeps your health vital and strong. Here's how it works: You eat something and the stomach and intestines breaks the food down into glucose. The cells need glucose for energy, but for the cells to be able to use glucose they also need insulin which the pancreas emits in the response to glucose.
Could you die if you had diabetes and didn't take your insulin?
Without insulin glucose can't enter cells that require it to generate energy, the body therefore passes out the message that it lacks fuel. This will result in a desire for eating sweet things in huge quantities, the body believes it's starving even though you are eating, however it can't use the fuel. The brain can survive with this pure glucose diet; however other body cells need insulin to allow the access of the glucose. Excess glucose is passed via the kidneys, leading to huge volumes of urine being produced, and an excessive thirst - two key signs of diabetes mellitus. So yes, you will die if you do not take your insulin.
What does insulin do to blood glucose?
Insulin response comes about from receptor tyrosine kinase. When insulin binds to the alpha portion of the RTK, the receptors dimerize. This results to its beta intracellular portion to autophosphorylate. This creates a binding site for IRS-1. When IRS-1 is activated, it recruits glut-4 receptors, allowing glucose to be taken in from the blood (therefore blood conc. will fall under insulin)
Which two hormones are responsible for the balancing of the glucose in the blood?
Actually there are about eight glucose regulating hormones in the blood. But the three you need to know are the following. Insulin- Lowers glucose blood concentration Glucagon- Increases glucose blood concentration Thyroxine- Increases glucose blood concentration They are used for different purposes however. Find out more on some revision sites or wikipedia
Why does insulin in the blood increase after meals?
Insulin controlls how the glucose injested is turned into fat. It also controls how much is removed to be turned into glycogen in the liver and muscles. It controls the amount of glucose transported to cells and respiration. Therefore, when we eat our pancreas supplies more insulin to be able to cope with the levels of sugar that we take in after meal times.Diabetics can produce too much insulin or too little insulin. Insulin injections need to be taken before meal times (consult a doctor) for diabetics in order to get the sugar to the cells. If the insulin is not administrated then the body will use reserves of glucose from the fat and muscles to respire and grow etc.
