Cells do not gain energy through facilitated diffusion. Facilitated diffusion is a passive process in which molecules move across the cell membrane from an area of higher concentration to lower concentration with the help of transport proteins, without the need for energy input. Cells use energy through other processes such as active transport and cellular respiration to maintain their functions.

What type of molecule is the MOST common energy source for all cells and enters the cell by facilitated diffusion?
Glucose is the most common energy source for cells and enters cells through facilitated diffusion via glucose transporters, such as the GLUT proteins. Once inside the cell, glucose undergoes cellular respiration to produce ATP, the cell's primary energy currency.
What processes are responsible for chemicals moving into throughout and out of the cell?
Chemicals move into and out of cells primarily through passive diffusion, facilitated diffusion, and active transport processes. Passive diffusion relies on concentration gradients, while facilitated diffusion involves the use of carrier proteins. Active transport uses energy to move molecules against their concentration gradient.
Sugar molecules can enter cells through the process of what?
Sugar molecules can enter cells through the process of facilitated diffusion or active transport. Facilitated diffusion involves the use of transporter proteins to move sugars across the cell membrane, while active transport requires energy to move sugars against a concentration gradient into the cell.
What is meant by passive transport of material across a membrane?
Passive transport is the movement of molecules across a cell membrane without the input of energy. This can occur through processes like diffusion and facilitated diffusion, where molecules move down their concentration gradient from an area of higher concentration to an area of lower concentration.
What is the process by which substances enter and leave cells and become distributed within cells?
Substances enter and leave cells through processes such as diffusion, facilitated diffusion, active transport, and endocytosis/exocytosis. Once inside the cell, substances can become distributed within cells through diffusion, cytoplasmic streaming, vesicular transport, and interactions with organelles.
Does the facilitated diffusion not require the cell to use energy?
It does not require the use of the cells energy.
What statements tells how facilitated diffusion differ from simple diffusion?
Particles move through cell membranes w/out the use of energy by cells.
What are two ways of moving things in and out of a cell that do not need energy?
transpiration and diffusion through cell walls.Tranpiration is only for plant cells and animals cells do not have a cell wall. For animal cells there is diffusion and omosis through cell membranes.diffusion, osmosis, and facilitated diffusion

What is facilitated transport?
Facilitated transport is a type of passive transport in cells where specific carrier proteins assist in the movement of molecules across the cell membrane. This process does not require energy input from the cell and operates through protein-mediated pathways, allowing certain molecules to move across the membrane according to concentration gradients.
What is the movement of materials through a cell membrane?
Movement of substances into and out of cells include passive mechanisms that do not require cellular energy (diffusion, facilitated diffusion, osmosis, and filtration) and active mechanisms that use cellular energy (active transport, endocytosis,and exocytosis).
The movement of oxygen into cells from the bloodstream is accomplished through?
The movement of oxygen into cells from the bloodstream is accomplished through diffusion. Oxygen diffuses from areas of higher concentration in the bloodstream to areas of lower concentration in the cells, facilitated by the concentration gradient between the two. This process is essential for cellular respiration and the production of energy in the form of ATP.

Passive transport is the movement of molecules across a cell membrane without the input of energy. This can occur through processes like diffusion and facilitated diffusion, where molecules move down their concentration gradient from an area of higher concentration to an area of lower concentration.
By which process does glucose move into red blood cells from the plasma?
Glucose moves into red blood cells through facilitated diffusion. In this process, glucose passes through specific membrane transport proteins called glucose transporters, such as GLUT1, which allow glucose to move down its concentration gradient and into the cell.
How does a polar substance get across a cells plasma membrane without the expendture of energy assuming it is more concentrated outside the cell?
Facilitated diffusion
