| Facilitated Diffusion Active Transport | Facilitated diffusion takes place down the gradient of concentration. Active transport takes place toward the gradient of concentration. |

What is the difference between facilitated diffusion and active transport quizlet?
What are the difference between them? they
both change the concentration level outside and inside the cell
. Active transport requires energy and moves low to high concentration. Facilitated diffusion is passive transport moves high to low.no energy.
What are the similarities between facilitated diffusion and active transport?
In facilitated diffusion, ions, sugars, and salts are transported across the membrane. In active transport, ions, sugars, and salts are also transported. The second similarity is that both facilitated diffusion and
active transport use proteins as their means of transporting their materials to and from the cell
.
What are two differences between active transport and facilitated diffusion?
Active transport is an active process meaning it requires the use of ATP, whereas
facilitated diffusion is
a passive process meaning it does not need ATP.To carry out the process active transport only requires carrier proteins; facilitated diffusion on the other hand involves protein channels or carriers.
What are the similarities between simple and facilitated diffusion?
Simple diffusion and facilitated diffusion are similar in
that both involve movement down the concentration gradient
. The difference is how the substance gets through the cell membrane.
What is the major difference between facilitated diffusion and passive diffusion?
| Simple Diffusion Facilitated Diffusion | Example of simple diffusion: passive transport of small nonpolar molecules across the plasma membrane Example of facilitated diffusion: passive transport of glucose and ions into and out of the cell |

What do facilitated diffusion active transport have in common?
What do facilitated diffusion and active transport have in common? How are they different?
They both change the concentration level inside and outside the cell
. Active transport requires energy and moves low concentration to high concentration.
What is the main difference between simple diffusion and facilitated diffusion quizlet?
Simple diffusion and facilitated diffusion are similar in that both involve movement down the concentration gradient. The difference is
how the substance gets through the cell membrane
. In simple diffusion, the substance passes between the phospholipids; in facilitated diffusion there are specialized membrane channels.
Is facilitated diffusion active or passive?
Facilitated diffusion is a type of
passive transport
. Even though facilitated diffusion involves transport proteins, it is still passive transport because the solute is moving down the concentration gradient.
Does facilitated diffusion use ATP?
Simple diffusion does not require energy:
facilitated diffusion requires a source of ATP
. Simple diffusion can only move material in the direction of a concentration gradient; facilitated diffusion moves materials with and against a concentration gradient.
Is osmosis An example of facilitated diffusion or active transport?
Osmosis is an example of
facilitated diffusion
. A – When a normal red blood cell is placed in an isotonic solution, water will move into and out of the cell at equal rates. The size of the cell will not change because there is no net movement of water.
What is the difference between active transport at and facilitated diffusion FD?
Facilitated diffusion(FD) is a passive movement whilst
active transport(AT) is an active movement
.
What are two types of facilitated diffusion?
Facilitated diffusion is performed by various types of proteins that are embedded within the cell membrane. While there are hundreds of different proteins throughout the cell, only two types are found associated with facilitated diffusion:
channel proteins and carrier proteins
.
What characteristic do simple diffusion and facilitated diffusion share?
Both require cellular energy for the transport of substances
. Both move a substance from a region of higher concentration to one of lower concentration without cellular energy.
Which of the following is common for both simple diffusion and facilitated diffusion?
They share some common characteristics which include the fact that both simple and facilitated diffusion are
passive processes
and therefore require no energy to take place as movement takes place down the concentration gradient of the molecules – this means that some molecules will be able to diffuse into the cell, …
What are examples of facilitated diffusion?
Examples of biological processes that entail facilitated diffusion are
glucose and amino acid transport, gas transport, and ion transport
. Facilitated diffusion is important because it regulates what goes in and what goes out of the cell.
