Why does bacterial meningitis cause a greatly lower than normal percentage of glucose to be present in CSF?
Bacterial meningitis disrupts the blood-brain barrier, allowing bacteria to enter the cerebrospinal fluid (CSF) and consume glucose as a nutrient source. This results in a decreased percentage of glucose in the CSF due to increased utilization by the bacteria. Additionally, the inflammatory response in the brain during bacterial meningitis can also affect glucose levels in the CSF.
Is glucose the preferred source of enery for the brain?
Yes, glucose is the preferred source of energy for the brain. The brain relies on glucose for fuel as it cannot store or produce energy from other sources. Adequate glucose supply is crucial for proper brain function and cognitive performance.
What is glucose the prefered source of energy for?
Glucose is the preferred source of energy for the brain, as it can cross the blood-brain barrier and be readily used by brain cells for their functions. Additionally, many other tissues in the body, such as red blood cells and kidney medulla, rely primarily on glucose for energy production.
What is the principle source of energy for brain cells?
Glucose is the primary source of energy for brain cells. It is broken down through a process called glycolysis to produce ATP, the primary energy currency of cells, which is used to power various cellular functions in the brain.
Is the blood brain barrier effective against glucose?
The blood-brain barrier (BBB) is effective at regulating the passage of substances between the bloodstream and the brain, but it does allow certain essential molecules, such as glucose, to cross. Glucose is transported into the brain via specialized glucose transporters, primarily GLUT1, which facilitate its entry to meet the energy demands of brain cells. Therefore, while the BBB is selective, it is not impermeable to glucose, ensuring that the brain receives the necessary nutrients.
Is glucose the primary fuel used by the brain and nervous system?
true
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 percentage of brain was used by Albert Einstein?
20 %
Is fat is the primary fuel for the brain?
While the brain can use both glucose and ketones for fuel, it has a preference for glucose. However, during periods of fasting or on a ketogenic diet, the brain can efficiently use ketones, which are produced from fat breakdown, as an alternative fuel source.

What is the best source of glucose for the brain?
The best source of glucose for the brain is carbohydrates, which are broken down into glucose during digestion and provide the brain with the energy it needs to function properly.
Is glucose the preferred source of enery for the brain?
Yes, glucose is the preferred source of energy for the brain. The brain relies on glucose for fuel as it cannot store or produce energy from other sources. Adequate glucose supply is crucial for proper brain function and cognitive performance.
How much percentage did newton used his brain?
Isaac Newton use his brain to its maximum level he use his brain to 110 %
Is glucose a source of energy for brain cells?
yes, glucose is the only source of energy for brain cells
Which type of glucose is not degraded in muscle?
according to what i read online it's the blood glucose, as the muscle leaves this blood for the brain use, because brain doesn't store glucose or glycogen as liver and muscle, and the only supply of glucose to brain is via blood glucose
Honey has the largest percentage of what?
Honey has the largest percentage of natural sugars, primarily fructose and glucose.
What is glucose the prefered source of energy for?
Glucose is the preferred source of energy for the brain, as it can cross the blood-brain barrier and be readily used by brain cells for their functions. Additionally, many other tissues in the body, such as red blood cells and kidney medulla, rely primarily on glucose for energy production.
