Active transport is a process that requires energy to move molecules across a cell membrane. In the case of glucose entering muscle cells, active transport proteins use energy to pump glucose molecules against their concentration gradient, allowing them to enter the cell even when there is a higher concentration of glucose outside the cell. This process ensures that muscle cells have a constant supply of glucose for energy production and muscle function.

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 is Movement from high glucose to low glucose?
Movement of glucose from an area of high concentration to an area of low concentration is known as passive transport or diffusion. Glucose molecules move down their concentration gradient in this process, requiring no energy input from the cell.
What are the example of active transport?
Examples of active transport include the sodium-potassium pump, which maintains the concentration gradients of sodium and potassium ions across cell membranes, and the transport of glucose by glucose transporters in the intestine and kidney. These processes require energy in the form of ATP to move molecules against their concentration gradients.
Does active transport require a transport protein?
Active transport requires the use of ATP because in active transport things move against the concentration gradient. Usually there is a protien pump (which is a form of a transport protien) that does this.
Identify 2 methods of Active transport?
Two methods of active transport are primary active transport, which uses energy in the form of ATP to move molecules against their concentration gradient, and secondary active transport, which uses the energy stored in an ion gradient to drive the movement of other molecules.

What is Movement from high glucose to low glucose?
Movement of glucose from an area of high concentration to an area of low concentration is known as passive transport or diffusion. Glucose molecules move down their concentration gradient in this process, requiring no energy input from the cell.
Is mineral movement into plant root an active transport or passive transport?
Mineral movement into plant roots is typically an active transport process. It requires energy to move minerals against their concentration gradient from the soil into the plant roots. Transport proteins such as pumps or carriers are involved in this process to facilitate the movement of minerals into the plant.
How does glucose concentration affect active transport?
Glucose concentration can affect active transport by influencing the rate of transport. In some cases, a higher glucose concentration can lead to an increased rate of active transport to maintain cellular homeostasis. Conversely, a lower glucose concentration may result in decreased active transport activity until a balance is restored.
The movement of glucose molecules across a plasma membrane from an area of lower glucose concentration to an area of higher glucose concentration occurs due to?
active transport, specifically through a process known as secondary active transport or cotransport. This process relies on the use of energy generated by the concentration gradient of another molecule, usually sodium ions, to drive the movement of glucose against its gradient.
Do cells in villi uptake glucose by active transport?
Yes, cells in the villi of the small intestine uptake glucose through active transport using specific membrane transport proteins like SGLT1. This process involves the movement of glucose molecules against their concentration gradient, requiring energy in the form of ATP.
How can glucose not pass through membranes?
Glucose is a polar molecule that cannot readily pass through nonpolar lipid bilayers of cell membranes. It requires specific transport proteins such as glucose transporters to facilitate its passage into and out of cells through facilitated diffusion or active transport. This selective transport process helps maintain glucose homeostasis within cells and the body.
Is the mineral movement into plant root passive transport or active transport?
active transport
Which substance in not removed from the lumen of the renal tubules by active transport?
Water is not removed by active transport in the renal tubules. It is primarily reabsorbed passively through osmosis following the movement of solutes like sodium and glucose.
What are the example of active transport?
Examples of active transport include the sodium-potassium pump, which maintains the concentration gradients of sodium and potassium ions across cell membranes, and the transport of glucose by glucose transporters in the intestine and kidney. These processes require energy in the form of ATP to move molecules against their concentration gradients.
How does a cell solve the problem of glucose being to big to pass through the cell membrane?
Cells use transport proteins, such as glucose transporters, to facilitate the movement of glucose molecules across the cell membrane. These transporters act as channels or carriers that allow glucose to pass through the membrane, overcoming the barrier posed by its size.
Examples of active transport?
Active transport is the movement of ions or molecules across a cell membrane into a region of higher concentration, which requires energy and is assisted by enzymes. Examples of active transport are: the uptake of glucose in the intestines of people and the uptake of mineral ions into the root hairs of plants.
