Is the movement of ions through a protein pump an active or passive process?
The movement of ions through a protein pump is an active process.
Is carrier proteins passive transport or active transport?
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.
What are examples of passive transport and active transport?
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.
Is facilitated diffusion type of active transport?
Facilitated diffusion is passive transport as no energy is used, and a protein channel is all that's required. After that it is simple diffusion down a concentration gradient. Anything with the word diffusion in it is passive transport. Diffusion is just the principle of passive transport.
Is a sodium potassium pump active or passive transport and describe why.?
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.
Is the movement of ions through a protein pump an active or passive process?
The movement of ions through a protein pump is an active process.
When molecule enters through the cell through protein pump is it classified as active or passive transport?
When a molecule enters the cell through a protein pump, it is classified as active transport. This process requires energy, typically in the form of ATP, to move molecules against their concentration gradient, from areas of lower concentration to higher concentration. In contrast, passive transport does not require energy and occurs along the concentration gradient.
Is carrier proteins passive transport or active transport?
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.
Is Na K pump active or passive?
In biology, an ion transporter, also called an ion pump, is a transmembrane protein that moves ions across a plasma membrane against their concentration gradient, in contrast to ion channels, where ions go through passive transport.
What are membrane structures that function in active transport?
Protein pumps, such as the sodium-potassium pump and the proton pump, are membrane structures that function in active transport by moving ions against their concentration gradients across the cell membrane. These pumps require energy, usually in the form of ATP, to transport substances.
What are examples of passive transport and active transport?
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.
Is glucose molecule passive or active transport?
Secondary active transport aka facilitated diffusion [depending on your teacher].
Through what type of proteins does active transport occur?
Active transport occurs through carrier proteins that pump molecules against their concentration gradient using energy from ATP. These carrier proteins undergo conformational changes to transport molecules across the cell membrane.
What is pump in active transport?
A pump in active transport refers to a protein pump found in cell membranes that uses energy, usually ATP, to actively transport molecules or ions against their concentration gradient. This process allows cells to regulate the concentration of substances inside the cell and is essential for maintaining proper cellular function. Examples include the sodium-potassium pump and the proton pump.
Is facilitated diffusion type of active transport?
Facilitated diffusion is passive transport as no energy is used, and a protein channel is all that's required. After that it is simple diffusion down a concentration gradient. Anything with the word diffusion in it is passive transport. Diffusion is just the principle of passive transport.

Passive and active transport?
Active Transpot. -Pumps -Endocytosis -Exocytosis Passive Transport - Diffusion -osmosis -Facilitated Diffusion active requires energy passive doesnt. active against concentration gradient, passive along concentration gradient.
