What else can I help you with?
What a physiological process in humans that utilizes either active transport or passive transport to generate a body function?
absorption of urea from bloodi only know one, i was hoping that someone could give some more. I know that the kidneys use active transport to absorb urea, and nitrogen from the blood. (Low concentration of urea, excess water etc. to a high concentration in the kidneys)
When will urea prills absorb moisture?
Urea prills can start to absorb moisture when exposed to high humidity or damp conditions. This absorption process can begin relatively quickly depending on the moisture levels in the surrounding environment. It is important to store urea prills in a dry place to prevent clumping and caking.
Is urea osmotically active?
Yes, urea is considered to be osmotically active. It can contribute to the osmotic pressure of a solution by attracting water molecules and affecting the overall concentration of solutes.
Is lipid absorption active transport?
No, lipid absorption is primarily a passive process. It occurs through simple diffusion in the small intestine, where lipids are broken down into smaller molecules and then absorbed into the bloodstream. Some specialized transport proteins may facilitate the absorption of certain lipids, but it is not considered active transport.
Why absorption rate of galactose is more than glucose?
The absorption rate of galactose is higher than glucose because galactose is transported into enterocytes by a secondary active transport mechanism that involves a carrier protein, which allows for faster absorption. In contrast, glucose is primarily absorbed through facilitated diffusion, which is a slower process.

When nutrients move from the digestive system and to the bloodstream?
That's called the process of absorption. The biological processes that allow absorption are diffusion and osmosis.

What is the process called when urea is formed?
It's called the Bosch-Meiser urea process. See https://en.wikipedia.org/wiki/Urea

Is urea produced from ammonia?
Yes, urea is produced from ammonia in a process called the Haber-Bosch process. In this process, ammonia is combined with carbon dioxide to produce urea, which is a common nitrogen-containing fertilizer.
How can one make urea?
Urea can be made by reacting ammonia with carbon dioxide in a process called the Haber-Bosch process. This reaction forms urea and water as products.
What is the process that requires the use of energy to move materials across a membrane?
Active transport is the process that requires the use of energy to move materials across a membrane. This process involves the movement of molecules against their concentration gradient, requiring energy input from the cell.
Absorbtion of digested food?
It is a process by which diffusible nutrients transfered from the gut into the blood or lymph by physico-chemical process and active transport. No absorption occurs in buccal cavity and very little absorption takes place in the stomach e.g. of alcohol. Particullarly all absorption takes place through the small intestine.
Why absorption rate of galactose is more than glucose?
The absorption rate of galactose is higher than glucose because galactose is transported into enterocytes by a secondary active transport mechanism that involves a carrier protein, which allows for faster absorption. In contrast, glucose is primarily absorbed through facilitated diffusion, which is a slower process.
How is urea reabsorbed?
40-50 % of filtered urea is reabsorbed through passive diffusion in the Proximal Convoluted Tubules. Loop of Henle, Distal Convoluted Tubules and Cortical Collecting Ducts are impermeable to urea. But secretion of urea happens in descending Loop of Henle (This helps to maintain the osmotic gradient in the medulla of the Kidney). There is also re-absorption of urea in the medullary collecting ducts.
