Active because concentration in cells must remain hight than in the blood.
Secondary active transport aka facilitated diffusion [depending on your teacher].
Chloride (Cl-) reabsorption in the kidneys primarily occurs through passive transport mechanisms, such as facilitated diffusion, often coupled with sodium (Na+) reabsorption. However, it can also involve active transport processes in certain segments of the renal tubule. Overall, while much of Cl- reabsorption is passive, the specific mechanisms can vary depending on the location within the nephron.
Carbon dioxide can diffuse passively through the cell membrane due to its small size and nonpolar nature. Water molecules can pass through the membrane via osmosis, a type of passive transport. Sodium ions are transported against their concentration gradient through active transport processes such as sodium-potassium pumps that require ATP for energy.
active transport -transport against concentration gradient that requires chemical energy passive transport- requires no energy at all
In passive transport the solute is driven across the cell until both sides of the membrane are equal. In active transport, energy causes the transporter to release the solute to only one side of the membrane.
reabsorbed passively in response. This passive movement helps maintain electrical neutrality and osmotic balance in the renal tubule.

P.I.S.O.- Potassium in Sodium out facilitated diffusion, active transport , and passive transport and simple diffusion.
The two types of cell trnsport it Passive Transport and Active Transport. Active Transport does require energy to move into and out of the cell. Passive Transport doesn't require energy to move into and out of the cell. Hope I helped!
Active Transpot. -Pumps -Endocytosis -Exocytosis Passive Transport - Diffusion -osmosis -Facilitated Diffusion active requires energy passive doesnt. active against concentration gradient, passive along concentration gradient.

Active transport requires energy to move substances across a cell membrane against their concentration gradient, whereas passive transport does not require energy and relies on the concentration gradient. Examples of active transport include the sodium-potassium pump and endocytosis.
Proteins that carry out passive transport include channel proteins and carrier proteins. Passive transport is "passive" because it does not use energy. The use of passive transport is also called "facilitated diffusion." Proteins that carry out passive transport includes the proton pump and the sodium-potassium pump; these require energy to function.
A sodium-potassium pump is considered active transport because it directly expends energy in the form of ATP to pump sodium out of the cell and potassium into the cell against their concentration gradients. This process helps maintain the cell's resting membrane potential and is essential for nerve conduction and muscle contractions.
Carrier proteins can use active or passive transport depending on what type of carrier protein it is (meaning what the protein transports). The form of passive transport that they use is facilitated diffusion. An example of active transport is the Sodium Potassium pump. Active transport requires ATP. Facilitated diffusion is used to transport polar molecules and ions that cannot directly cross the cell membrane. Facilitated diffusion doesn't require energy.
It can dehydrate a fruit or vegetable by passive transport. The higher concentration of water goes to the lower concentration and thereby "sucking" the water out of fruits and vegetables.
