What is the process that actively moves substances from the blood into the nephron?
in the ascending limb of the loop of Henle
What is the process of reabsorption as it occurs in nephrons?
Glucose reabsorption takes place in the proximal renal tubule. This tubule is a portion of the nephron that contains fluid. The functions of the nephron include the reabsorption and secretion of various substances like ions, glucose, and amino acids.
Is endocytosis an example of diffusion?
Endocytosis is NOT an example of diffusion. It is an example of active transport whereas diffusion is a type of passive transport. The difference lies in the fact that diffusion does not require energy to take place, and endocytosis does.
This transport process moves substances agaisnt a concentrating gradient and requires energy?
active transport
What process requires cells to expend energy in the form of ATP?
active transport
What is the nephron process?
The nephron process is where the blood enters the glomerulus and is absorbed. It is then processed through the kidney's and turned into urine.
An example of passive transport process is?
Diffusion, filtration, and osmosis. Diffusion.
What part of the nephron is involved in the glomerular filtration process of urine formation?
filtration takes place only at glomeruli part of nephron and nowhere else.
What is the process that actively moves substances from the blood into the nephron?
in the ascending limb of the loop of Henle
This is a nephron process that results in a substance in blood entering the already formed filtrate?
secretion
Which structure of the kidney actually carries out the purification process?
The basic filtering unit is called a nephron.
The process by which the renal tubule actively moves substances from the blood into the nephron to be excreted?
Tubular secretion
What is the movement of material through a membrane?
This movement occurs through several mechanisms.
Name the excretory unit of kidney?
The nephrons are where the filtration process occurs. If you want a more complex answer, ask about the process itself.
Most materials are reabsorbed from nephron tubules into surrounding blood vessels by the process known as?
Selective reabsorption
The process of filtration takes place in a structure called the?
It takes place in a part of the kidney called the nephron.
How the cell obtain water without using energy?
The most common form of transport for water into and out of cells is normally through the process of osmosis.This is the diffusion of water molecules from an area of high water potential to low water potential, and therefore doesn't require energy.For example, if there is a higher concentration of water outside the cell as opposed to inside the cell, then water will diffuse into the cell across the partially permeable membrane to give a net gain of water inside the cell. This is because it is travelling down the water potential gradient. Therefore the cell will gain water without using energy.In the kidney, there is a structure called the nephron. Water is lost through ultrafiltration and needs to be gained back so that we do not waste the water. 65% of the water is diffused back into the blood stream through osmosis as the water potential is higher in the nephron than the surrounding blood capillaries. More water then diffuses out of the nephron into the surrounding cells of the kidney. This is achieved through the active transport (using energy) of ions out of the nephron into these surrounding cells. Ions are solutes thus the water potential of the cells is reduced while the water potential of the nephron is increased. As a result, more water diffuses by osmosis out of the nephron and remains in the body.
