Why does active transport require more energy than osmosis or facilitated diffusion?
Wiki User
∙ 6y ago
Active transport requires more energy than diffusion this is because during active transport, the molecules are being transported against and toward the concentration gradient whereas in diffusion, the molecules go from the concentration gradient.

In facilitated diffusion which process does not require energy?
Simple and facilitated diffusion are a part of passive transport. This refers to the movement of molecules, atoms and ions across the cell membrane. In both of these processes, molecules move from areas of high concentration to areas of lower concentration because equilibrium is trying to be maintained in living organisms. Simple diffusion just happens randomly and without any aides. Facilitated diffusion uses proteins in the cell membrane to guide polar molecules and ions in and out of the membrane (always to areas of lower concentration) and DOES NOT require ENERGY.Only active diffusion requires energy.
What types of ways are available to safely transport cattle?
There are typically two ways to transport cattle and they are usually determined by distance. For shorter distances, rail transport is the most common method. Longer distances usually require road motor vehicles specifically designed for this transport.
Are you allowed to transport chickens and turkeys across state lines?
To transport chickens and turkeys across state lines, there are certain requirements that must be met that require testing. These laws vary from state to state so make sure you are following the rules!
Describe one example of diffusion in the human body?
Three examples of diffusion in the human body are:Photosynthesis produces oxygen inside the cell.The concentration of oxygen molecules becomes higher inside the cell than outside.and oxygen molecules move out of the cell by diffusion.I hope this helps, good luck!Even_though,_I_am_still_at_school,_in_my_experience, humans_DON'T_photosynthesise!">Even though, I am still at school, in my experience, humans DON'T photosynthesise!YES (THIS GUY IS CORRECT)(THE OTHER GUY, IS NOT CORRECT)that is just a stupid answer. any educated person would know that photosynthesis only occurs in plants.this may, or may not help you, but still:'Oxygen diffuses into red blood cells in the lungs, while Carbon Dioxide is diffusing out of red blood cells at the same time. Nutrients diffuse from the intestines into the blood. In the kidneys, water and other nutrients diffuse by condensing the waste products in the urine and reabsorbs majority of the water.May I STRESS that the first answer is indeed incorrect as humans DO NOT PHOTOSYNTHESIZE. For Diffusion, there are many examples, but to add to those above, some main ones are the diffusion of Oxygen in the air through the cornea and into the eye, as the eye has an insufficient quantity of blood vessels. furthermore, diffusion occurs in the stomach, where medicine diffuses through its capsule, through the stomach lining, and into the blood stream. Also, to add to the list is nutrients diffusing through the blood vessel lining, from the blood stream and into cells where it is required. Sometimes, these nutrients require transmembrane proteins, which change shape to allow the nutrients through, to enter the cell.The first answer is actually correct. Humans sunbathe to photosynthesize. Why do you think your skin becomes leafy after you get sun burnt? Answer- You are actually evolving into a tree. First guy, your're correct.
When do puppies require food?
Puppies need food when they are hungry.
Is osmosis an example of facilitated diffusion or active transport?
No. Facilitated diffusion is an example of passive transport because it does not require the cell to expend energy.
Does osmosis or facilitated diffusion require the presence of membrane channels?
facilitated diffusion
How is facilitated diffusion diferant froma an active transport?
Facilitated diffusion is a type of passive transport which does not require the cell to expend energy.
What two processes transport materials through the semi-permable membrane?
Considering the cell membrane itself, processes include diffusion, osmosis, facilitated diffusion (passive processes that do not require energy) and active transport (an active process that requires energy).
Are diffusion and osmosis passive or active transports?
Diffusion and osmosis are passive and do not require energy.
What are the three transport processes that do not require cell energy?
Passive Transport,Facilitated Diffusion, and Simple Diffusion
How is active transport different than simple and facilitated diffusion?
simple and facilitated diffusion don't require energy and are forms of passive transport. Active transport requires energy
What type of Transport in a cell does not require energy?
Passive transport, such as diffusion, does not require any external energy from the external source because this process is due to the net movement of molecules or ions from a region of higher concentration t a region where their concentration is lower.
Is facilitated diffusion an active transport?
no it is not because it does not require the use of ATP
Is osmosis a passive or active transport and how?
The four main kinds of passive transport are diffusion, facilitated diffusion, filtration and osmosis. Osmosis always deals with the movement of water across a semipermeable membrane. Water always moves toward the side that is higher in solutes (mainly salt). It does this to balance the two sides. Osmosis always follows salt is one of the best ways to remember this.
How is facilitated diffusion different from passive transport?
Mediated Transport has an extra step of binding to a carrier protein, while Passive transport does not bind to a protein. Both of them however, move along the concentration gradient (High--> Low)
Which form of transport across the cell membrane does not require energy but a carrier protein?
Facilitated transport.
