What movement of the substances through a cell membrane against a concentration gradient requires energy?
no because it is a form of passive transport. only active transport requires energy. facilitated diffusion just means that it cant be just absorbed through the membrane, it must go through specific chanels or be helped by transport proteins. but because facilitated diffusion moves from higher to lower concentrations, it requires no energy.
When water moves through an area of higher concentration to lower concentration?
When a region of higher concentration to a region of Lower concentration against the gradient which requires Energy is called Active Transport
Proceeds Against a concentration Gradient requires a carrier?
Solute pump
What is the transport of materials against a concentration gradient called?
The process of moving materials against a concentration gradient is called active transport. Active transport generally uses a protein pump to move molecules from an area of low concentration to an area of high concentration; in order to perform an active transport, the cell must use some of its energy to initiate the reaction.
How does facilitated transport differ from active transport?
Simple diffusion = flow of small molecules ALONG the concentration gradient, does NOT require energy. facilitated diffusion = flow of molecules ALONG the concentration gradient with help of CARRIER PROTIENS or CHANNELS, does NOT require energy active transport= flow of larger or charged molecules AGAINST their concentration gradient, REQUIRES input of ENERGY in the form of ATP.)

What is the cellular movement of a substance that requires the use of energy.?
what is the cellular movement of a substance that requires the use of energy. what is the word for it
What is endocytosis's concentration gradient?
Yes - as endocytosis requires energy.
Proceeds Against a concentration Gradient requires a carrier?
Solute pump
What moves up a concentration gradient and requires a carrier?
Primary Active Transport.
If diffusion is going to occur there has to be what?
A difference in the concentration throughout space because diffusion doesn't just happen in a cell or aqueous solution by definition diffusion is just from high to low concentration
Do Substances naturally diffuse up a concentration?
no down a concentration gradient high to low if its low to high it requires energy
Why active transport requires energy?
Active transportation is taken place against concentration gradient. So this requires energy .
Does active transport move with or against the gradient?
Against the gradient. It requires energy because it's going against the concentration of high to low.
What is the transport of materials against a concentration gradient called?
The process of moving materials against a concentration gradient is called active transport. Active transport generally uses a protein pump to move molecules from an area of low concentration to an area of high concentration; in order to perform an active transport, the cell must use some of its energy to initiate the reaction.
Is active or passive transport involved?
In active transport the ATP is used to pump molecules up the concentration gradient. Transport of molecules occurs from a low concentration of solute to high concentration of solute and requires cellular energy. While passive transport involves carriers, channels, or direct diffusion through a membrane.
