What method of studying the brian involves the insertion of radioactive glucose (sugar) into a vein?
The method you're referring to is called positron emission tomography (PET) scan. In this procedure, a small amount of radioactive glucose is injected into a vein, allowing researchers to track its uptake in different regions of the brain. This helps visualize brain activity and metabolism, providing insights into various cognitive processes.

What method of studying the brain invovles the insertion of radioactive glucose sugar into a vein?
Positron Emission Tomography (PET) is a method of studying the brain that involves the insertion of radioactive glucose sugar into a vein. This technique is used to measure brain activity by tracking the metabolism of glucose in different regions of the brain.
Technique that measures the levels of activity of different areas of the brain by tracing their consumption of a radioactive form of glucose?
The technique is called positron emission tomography (PET). It involves injecting a radioactive form of glucose into the bloodstream, which is then taken up by active brain regions. The scanner detects the emitted positrons to create a map of brain activity.
Why do humans need carbohydrates?
Carbohydrates are the body's primary source of energy. They are broken down into glucose, which is used by cells for fuel, particularly in the brain and muscles. Carbohydrates also play a role in maintaining healthy digestion and providing a feeling of satiety.
How can stress change physiological measurements?
Stress can increase heart rate, blood pressure, and release stress hormones like cortisol, impacting the body's overall response. It can also affect blood glucose levels, digestive processes, and immune system function, leading to potential long-term health implications if stress is chronic or severe.
What would be would be most useful for detecting the brain areas that are most active as a person performs mathematical calculations?
Functional magnetic resonance imaging (fMRI) would be most useful for detecting the brain areas that are most active as a person performs mathematical calculations. fMRI measures changes in blood flow related to neural activity, providing detailed images of brain activity during specific tasks. This method can help identify regions of the brain that are involved in mathematical processing.

What method of studying the brain involves the insertion of radioactive glucose (sugar) into a vein?
The method is called positron emission tomography (PET). Radioactive glucose is injected into the bloodstream, and imaging technology detects the radioactive particles to show brain activity and metabolism. This helps researchers understand which brain areas are active during specific tasks or at rest.
How many molecules of radioactive alcohol are formed from each molecule of glucose?
One molecule of glucose can produce 2 molecules of radioactive alcohol through the process of fermentation, where glucose is converted into ethanol and carbon dioxide by yeast.
If Plants are in an illuminated chamber and are supplied with carbon dioxide that has radioactive carbon atoms. In what molecule will the radioactivity be found later?
The radioactivity will be found in glucose, as it is the product of photosynthesis where carbon dioxide is converted into glucose using light energy. The radioactive carbon atoms from the carbon dioxide will be incorporated into the glucose molecule during photosynthesis.

What is is function of glucagon?
It involves in balancing glucose level.It increases the level.
Which process involves making glucose without energy from sunlight?
Chemosynthesis
A culture of bacteria growing aerobically is fed glucose containing radioactive carbon and is then examined During the citric acid cycle radioactive would first appear in?
The radioactive carbon would first appear in citrate during the citric acid cycle. Citrate is the first intermediate formed in the citric acid cycle when acetyl-CoA combines with oxaloacetate. The labeled carbon from the glucose will be incorporated into citrate during this step.
What type of radioactive nuclide is injected into a person who is about to undergo a PET scan?
The radioactive nuclide typically used in a PET scan is fluorine-18, which is commonly attached to a glucose molecule to form fluorodeoxyglucose (FDG). This radiotracer is injected into the patient and accumulates in tissues with high metabolic activity, allowing the PET scanner to detect areas of increased glucose uptake, such as in tumors.
What tool is used in a hospital to look at blood flow in a brain?
Usually a PET scanner (positron emission tomography scanner) with radioactive glucose. Note: following this test you will be slightly radioactive for about 10 to 12 hours.
What is the process of producing glucose from non-glucose sources called?
The process of producing glucose from non-glucose sources is called gluconeogenesis. It involves converting molecules like amino acids, glycerol, and lactate into glucose in the liver and kidneys to maintain blood sugar levels.
