What is the difference between an antiporter and a symporter in terms of their mechanisms of transport?
An antiporter moves two different molecules in opposite directions across a cell membrane, while a symporter moves two different molecules in the same direction.
Does glucose enter a cell by active transport?
GLUT1 is a passive protein transport. Glucose with GLUT1 can only be transported from high to low concentration. With the sodium - glucose symporter it's possible to transport glucose from low to high concentration.
What ways can cells move things by active transport?
. One method is that transport proteins in the cell membrane "pick up" molecules from outside the cell and carry them in, while using energy in the process. A second method is that the cell membrane surrounds a particle and takes it in.
What is the difference between an antiporter and a symporter in terms of their mechanisms of transport?
An antiporter moves two different molecules in opposite directions across a cell membrane, while a symporter moves two different molecules in the same direction.
What A symporter will transport across the cell membrane.?
2 different ion or molecule in the same direction
Why will inhibition of the symporter lead to an increase in urine volume?
Inhibition of the symporter, which typically reabsorbs sodium and other solutes in the renal tubules, reduces the reabsorption of these substances back into the bloodstream. As a result, more sodium and solutes remain in the tubular fluid, leading to increased osmolarity of the urine. This osmotic effect draws more water into the urine through osmosis, ultimately increasing urine volume. Consequently, the overall reabsorption of water is decreased, leading to diuresis.
What happens to glucose in the small intestine?
It gets absorbed into the blood stream via Lumen and a Glucose/Na+ symporter, Na+/K+ atpase and glucose 2 uniporter, but essentially is absorbed into the blood stream.
What is the glucose hitching a ride with?
Glucose hitches a ride with sodium through a symporter protein on the cell membrane. This process is known as secondary active transport, where the energy stored in the sodium gradient is used to transport glucose into the cell against its concentration gradient.
Movement of glucose across cell membrane of intestine?
Glucose can move via two ways: 1. With the Sodium/glucose pump. As sodium is diffusing back into the cell the glucose will attach itself (co-transport) as a symporter across the membrane. The sodium is going with the gradient and the glucose is moving against its gradient. Therefore, Indirect active transport via a symporter as a co-transporter. 2. By facillitated diffusion by attaching itself to a proten carrier glucose will move with the gradient into the cell. This means that glucose it the only molecule that can enter or leave a cell under two different transportation modes.
What is the energy source for co-transport?
The energy source for co-transport is typically the concentration gradient of one substance that is established by an active transport process. This concentration gradient drives the movement of another substance against its own concentration gradient through a symporter protein.
What part of the nephron do thiazide diuretics work on?
Thiazide diuretics primarily act on the distal convoluted tubule of the nephron. They inhibit the sodium-chloride symporter, leading to reduced reabsorption of sodium and chloride ions. This action increases urine output and decreases fluid retention, making thiazides effective in treating conditions like hypertension and edema.
Do Thiazide Diuretics decrease renal excretion of Phosphate?
No, Thiazide Diuretics actually increase renal excretion of Phosphate. They inhibit the sodium-chloride symporter in the distal convoluted tubule of the kidney, leading to increased excretion of sodium, chloride, and also phosphate.
What is they carrier type that moves two dilutes in the same direction across a membrane?
The carrier type that moves two solutes in the same direction across a membrane is known as a symporter. Symporters facilitate the simultaneous transport of two different molecules or ions, typically one along its concentration gradient and the other against its gradient. This process is often coupled with the movement of ions like sodium or protons, which provides the necessary energy for the transport.
Which type of active transport protein moves two molecules into the cell at the same time?
The type of active transport protein that moves two molecules into the cell at the same time is called a symporter. Symporters utilize the energy from the movement of one molecule down its concentration gradient to drive the simultaneous transport of another molecule against its gradient. This mechanism is crucial for various cellular processes, including nutrient uptake and ion regulation.
Does glucose enter a cell by active transport?
GLUT1 is a passive protein transport. Glucose with GLUT1 can only be transported from high to low concentration. With the sodium - glucose symporter it's possible to transport glucose from low to high concentration.
