Is glucose molecule passive or active transport?
Secondary active transport aka facilitated diffusion [depending on your teacher].
How carbon dioxide water and sodium ions are transported across the cell membrane by both passive and active transport?
Carbon dioxide cannot be transported across the membrane by passive transport. However, water and sodium ions can be transported using passive transport.
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.
What are the different types of cell transport?
active transport -transport against concentration gradient that requires chemical energy passive transport- requires no energy at all
Sodium ions are pumped out of a red blood cell?
passive transport
Whenever sodium ions are reabsorbed through the wall of the renal tubule be active transport chloride ions are?
reabsorbed by active transport
Is a sodium potassium pump active or passive transport and describe why.?
Potassium is distributed by passive diffusion.
Is glucose molecule passive or active transport?
Secondary active transport aka facilitated diffusion [depending on your teacher].

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.
How does diffusion take place in the body?
P.I.S.O.- Potassium in Sodium out facilitated diffusion, active transport , and passive transport and simple diffusion.
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 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.
The Na-K pump is an example of active transport?
Bulk Transport is an example of active transport. The process by which amoeba engulfs its food and secretes is a type of active transport. Amoeba forms false feet like pseudopodia and engulf food.Active and Passive transport both are related with plasma membrane. Active Transport is the transport of food across plasma membrane with expenditure of energy.
What can sodium chloride do?
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.
Whats the difference between passive transport and active transport?
Active transport requires energy and Passive transport requires no energy.Passive transport is a process which is carried out along the concentration gradient. For example, if the concentration of water is more outside the cell than inside, water will flow into the cell. Simply put, it is actually diffusion which occurs in passive transport and hence, no energy is required.Active transport, however, is carried out against the concentration gradient and hence requires energy. An example of active transport is the uptake of salt by cells through sodium pump.Active transport requires energy and moves particles up their concentration gradient. Passive transport doesn't require energy and moves particles down their concentration gradient.
To maintain solute concentration gradient in the renal medulla what is required?
active transport of sodium and chloride ions from the ascending limb of the loop of Henle.
