How is active transport different from diffusion quizlet?
facilitated diffusion uses a substrate to bind to a protein carrier, whereas active transport does not. facilitated diffusion moves water across the cell membrane, whereas active transport does not. ATP is necessary for active transport, but not for facilitated diffusion.

What is the main difference between passive diffusion and active transport quizlet?
Passive transport moves molecules WITH the concentration gradient (high to low), while active transport moves molecules AGAINST the concentration gradient (Low to High).

What are two differences between simple diffusion and active transport?
simple diffusion moves molecules down concentration gradient while active transport takes them against concentration gradient. Simple diffusion is passive, which means it does not require energy, while active transport does.

How is active transport different from diffusion GCSE?
In diffusion and osmosis, substances move down a concentration gradient. However, active transport moves substances against a concentration gradient. Active transport is an active process, which means it requires energy from respiration.

What are two differences between active transport and facilitated diffusion quizlet?
-Active transport can move solutes in either direction across a membrane, but facilitated diffusion can only move in one direction. -Active transport involves transport proteins, and facilitated diffusion does not. -Facilitated diffusion can move solutes against a concentration gradient, and active transport cannot.

What is the main difference between passive diffusion and active transport?
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 is a major difference between active and passive transport quizlet?
Passive transport moves materials through a cell membrane without using energy while active transport uses energy to move materials through a cell membrane. They are both moving materials through the cell membrane.

What is the difference between diffusion and active transport quizlet?
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 is the difference between passive transport and passive diffusion?
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 difference between simple diffusion and active transport?
The primary difference between active transport and diffusion is that active transport needs cellular energy to transport the molecules against the concentration gradient. In contrast, diffusion refers to the passive transport method where the molecules move across the cell membrane through a concentration gradient.

What are the two main difference between active transport and diffusion?
Facilitated diffusion occurs along a concentration gradient from high concentration to low concentration and does not require energy, while active transport from low concentration to high concentration occurs against the concentration gradient and requires energy.
