Glucose concentration decreases in body fluids when cells take up glucose for energy production, storage, or use in metabolic pathways. This uptake helps regulate blood glucose levels and maintain a balance in the body's energy supply. Additionally, insulin plays a key role in facilitating glucose uptake into cells, contributing to the decrease in glucose concentration in body fluids.
Muscle requires glucose, and so there is not the same concentration of glucose in blood entering and exiting a muscle. The exiting blood will be lower in glucose.
Insulin is the hormone that decreases blood glucose levels by facilitating the transport of glucose from the bloodstream into body cells for energy production and storage.
Yes
This process is known as glycogenolysis, where stored glycogen in the liver is broken down into glucose and released into the blood to maintain blood glucose levels.
Insulin causes a decrease in the concentration of blood glucose by promoting the uptake of glucose into cells, especially muscle and adipose tissue. It also stimulates the storage of glucose as glycogen in the liver and muscle.
Regulating blood glucose concentration
glucagon
Glucose in the filtrate is reabsorbed from the nephron back into the bloodstream through the walls of the renal tubules. This process occurs mainly in the proximal convoluted tubule, where glucose transporters actively reabsorb glucose to maintain its concentration in the blood. If there is excess glucose that cannot be reabsorbed, it may be excreted in the urine.
Glucagon is catabolic and increases blood glucose levels, insulin is anabolic decreases blood glucose levels.
i know it's higher than corresponding blood glucose concentration from 10 - 15%
The concentration of glucose is typically higher in plasma (blood) compared to cerebrospinal fluid because glucose is actively transported from blood into the brain. Normal CSF glucose levels are around 60-70% of plasma glucose levels.
