glucose & sodium
Chloroplasts utilize active transport to move hydrogen ions against their concentration gradient. This process relies on energy, typically derived from ATP, to pump protons into the thylakoid lumen during photosynthesis. The resulting gradient of hydrogen ions is then used to drive ATP synthesis through chemiosmosis, ultimately supporting the production of energy-rich molecules.
Sodium ions are primarily transported into the cell through the sodium-potassium pump, an active transport mechanism that utilizes ATP to move ions against their concentration gradient. Potassium ions move between red blood cells and plasma mainly through passive diffusion, where they move down their concentration gradient through specific channels in the cell membrane.
the sodium-potassium pump, an active transport protein that uses energy from ATP to move sodium ions out of the cell against their concentration gradient.
An ion pump actively transports ions across the cell membrane against their concentration gradient using ATP energy, while an ion channel is a passive protein that allows ions to move down their concentration gradient in or out of the cell membrane. Ion pumps are selective in the ions they transport, while ion channels are typically nonspecific or selective for specific ions.
During active transport, a cell must expand its energy in the form of ATP to pump molecules or ions across a membrane against their concentration gradient. This process requires energy to create a concentration gradient and move substances from low to high concentration.
An ion pump, such as the sodium-potassium pump, transports ions against their concentration gradient by using energy (ATP) to move ions from an area of lower concentration to an area of higher concentration. This process is important for maintaining cell membrane potentials and regulating the movement of ions across cell membranes.
Sodium ions can be moved across cell membranes through the process of active transport, which utilizes energy from ATP to pump ions against their concentration gradient. Sodium ions can also move through facilitated diffusion, where they move down their concentration gradient with the help of transport proteins.

the sodium-potassium pump, an active transport protein that uses energy from ATP to move sodium ions out of the cell against their concentration gradient.
This process is called the sodium-potassium pump. It uses ATP to pump sodium ions out of the cell against their concentration gradient and pump potassium ions back into the cell against their concentration gradient. This mechanism helps maintain the appropriate balance of sodium and potassium ions inside and outside the cell, which is crucial for cellular functions such as nerve transmission and muscle contraction.
Potassium ions (K+) are found in high concentration inside the neuron compared to outside. This concentration gradient is maintained by the sodium-potassium pump.
An ion pump actively transports ions across the cell membrane against their concentration gradient using ATP energy, while an ion channel is a passive protein that allows ions to move down their concentration gradient in or out of the cell membrane. Ion pumps are selective in the ions they transport, while ion channels are typically nonspecific or selective for specific ions.
In biological systems, substances can move against the concentration gradient through a process called active transport. This process requires energy to pump molecules or ions across a cell membrane, from an area of lower concentration to an area of higher concentration. This allows cells to maintain specific internal concentrations of substances, even when the external environment has different concentrations.
Active transport.
During active transport, a cell must expand its energy in the form of ATP to pump molecules or ions across a membrane against their concentration gradient. This process requires energy to create a concentration gradient and move substances from low to high concentration.
By the action of electrons going down the electron transfer chain the energy is provided to pump H + into the outer lumen of the mitochondria creating the concentration gradient for H + to come down it's concentration gradient through the ATP synthase.
