Passive diffusion is thus a nonselective process by which any molecule able to dissolve in the phospholipid bilayer is able to cross the plasma membrane and ...
The internal composition of the cell is maintained because the plasma membrane is selectively permeable to small molecules. Most biological molecules are unable to diffuse through the phospholipid bilayer, so the plasma membrane forms a barrier that blocks the free exchange of molecules between the cytoplasm and the external environment of the cell. Specific transport proteins (carrier proteins and channel proteins) then mediate the selective passage of small molecules across the membrane, allowing the cell to control the composition of its cytoplasm.

FAQs
Which Of The Following Statements Best Explains The Processes Of Passive And Active Transport? ›
Which of the following statements best explains the processes of passive and active transport? b. passive transport is the net movement of substances down a concentration gradient that does not require metabolic energy. Active transport is the movement of substances up a concentration gradient that requires energy.
What best explains the processes of passive and active transport? ›Active transport requires energy to move substances against a concentration or electrical gradient, like a canoeist paddling upstream. Passive transport, on the other hand, does not require energy as substances move along their gradient, similar to a canoeist drifting downstream.
Which of the following best explains the difference between passive and active transport within the cell membrane? ›Answer and Explanation:
The major difference between active transport and passive transport, is that active transport requires an input of energy usually in the form of ATP. Passive transport drives its energy from concentration gradients and therefore does not require an input of energy to move.
What is the difference between active and passive transport? Active transport requires energy but passive transport does not. When particles go from high to low molecules. When water diffuses across a membrane.
Which statement best describes passive transport quizlet? ›Which of the following best describes passive transport? It does not require energy and moves molecules with the concentration gradient.
What is the difference between active and passive transport passive transport? ›Key Points on Active and Passive Transport
Active transport requires energy for the movement of molecules whereas passive transport does not require energy for the movement of molecules.
Examples. Examples of active transport include a sodium pump, glucose selection in the intestines, and the uptake of mineral ions by plant roots. Passive transport occurs in the kidneys and the liver, and in the alveoli of the lungs when they exchange oxygen and carbon dioxide.
What are the two 2 main differences between active and passive transport? ›| Active Transport | Passive Transport |
|---|---|
| It is a quick process. | It is a moderately slow process. |
| It Occurs in one direction. | It occurs bidirectionally. |
| It is Affected by temperature. | It is not affected by temperature. |
| It requires carrier proteins. | It carrier proteins are not involved |
There are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.
What's the main difference between passive and active transport what organelle controls cell transport? ›Moving things in and out of the cell is an important role of the plasma membrane. It controls everything that enters and leaves the cell. There are two basic ways that substances can cross the plasma membrane: passive transport, which requires no energy; and active transport, which requires energy.
Is it true the main difference between active and passive transport is the need for transport proteins? ›
Active transport and passive transport both require the use of transport proteins to move a substrate into or out of a cell. The difference between the two processes is whether or not energy is required. Passive transport moves substances down their concentration gradient, and therefore does not require energy input.
Which of the following is the best definition of passive transport? ›Passive transport is a naturally occurring phenomenon and does not require the cell to expend energy to accomplish the movement. In passive transport, substances move from an area of higher concentration to an area of lower concentration in a process called diffusion.
What is the best explanation for passive transport? ›Passive transport is the fundamental movement of ions and other molecular substances within the cells along the concentration gradient, without any external energy. It is also known as passive diffusion.
What would be the best way to describe passive transport? ›Passive transport is defined as a type of transport that moves substances from an area of greater concentration to an area of lesser concentration. Thus, the movement of substances is along a concentration gradient.
What determines whether a transport process is active or passive quizlet? ›What determnes whether a transport process is active or passive? Whether or not a cell must provice ATP; if so, it is an active process. a form of active transport in which a cell transports molecules (such as proteins) into the cell by engulfing them in an energy-using process.
What is the process of diffusion is it active or passive transport? ›Passive transport, most commonly by diffusion, occurs along a concentration gradient from high to low concentration. No energy is necessary for this mode of transport.
