What else can I help you with?
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 process involves making glucose without light energy form the sun?
Gluconeogenesis is the process that involves making glucose from non-carbohydrate precursors, such as amino acids and glycerol, without the need for light energy from the sun. This process typically occurs in the liver and kidneys to maintain blood glucose levels when dietary sources are limited.
The digestion of maltose involves the?
enzymatic breakdown of maltose into glucose molecules by the enzyme maltase in the small intestine. This process allows for the absorption of glucose into the bloodstream for energy production and other metabolic processes.
How is glucose transported into the cell and what mechanisms are involved in this process?
Glucose is transported into the cell through a process called facilitated diffusion. This process involves the use of specific proteins called glucose transporters, such as GLUT proteins, which help move glucose across the cell membrane. These transporters bind to glucose molecules and facilitate their passage into the cell, allowing for the uptake of glucose for energy production.
What method of studying the brain involves the insertion of radioactive glucose into a vein?
PET - Positron Emission Tomography
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.
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.
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.
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.
If you expose a photosynthesizing plant to water that contains both radioactive H and radioactive O in which of the products of photosynthesis will the radioactive H and O show up?
In photosynthesis, water (H₂O) is split during the light-dependent reactions, releasing oxygen and producing energy-rich compounds. If a photosynthesizing plant is exposed to water containing radioactive hydrogen (H) and radioactive oxygen (O), the radioactive hydrogen will be incorporated into glucose and other organic molecules, while the radioactive oxygen will be released as a byproduct during the formation of molecular oxygen (O₂). Thus, radioactive H will appear in the glucose, and radioactive O will be found in the released O₂.
What is is function of glucagon?
It involves in balancing glucose level.It increases the level.

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.
Which process involves making glucose without energy from sunlight?
Chemosynthesis
