What else can I help you with?
Does facilitated diffusion require energy to transport molecules across the cell membrane?
Facilitated diffusion does not require energy to transport molecules across the cell membrane.
Does facilitated transport require energy for the movement of molecules across the cell membrane?
Yes, facilitated transport does require energy for the movement of molecules across the cell membrane.
What kind of transport across a membrane does not require energy?
Passive transport does not require energy as it allows molecules to move across a membrane from an area of higher concentration to an area of lower concentration. Examples of passive transport include diffusion, osmosis, and facilitated diffusion.
What motion of particles across a membrane requires energy?
Movement across a membrane that does require energy is called active transport.
What require the use of energy to move a molecule across a cell membrane?
Active transport
What process require ATP energy to transport materials across a selectively premeable membrane into the cell?
active transport
Which form of transport across the cell membrane does not require energy but a carrier protein?
Facilitated diffusion does not require energy but relies on carrier proteins to transport molecules across the cell membrane. The carrier proteins assist in the movement of specific molecules down their concentration gradient.
Which transport does not require cell energy?
Diffusion is per definition a passive transport process.
How does facilitated transport differ from active transport in terms of the energy requirements and mechanisms involved in moving molecules across a cell membrane?
Facilitated transport and active transport are two ways molecules can move across a cell membrane. Facilitated transport does not require energy from the cell, while active transport does require energy in the form of ATP. Facilitated transport uses carrier proteins to help molecules move across the membrane, while active transport uses pumps to move molecules against their concentration gradient.
What is the difference between active transport and osmosis?
Osmosis is the diffusion of water across a membrane, and does not require the input of energy. Active transport requires energy input.
Does the process of endo and exocytosis require energy?
Yes, both endocytosis and exocytosis require energy in the form of ATP to transport molecules across the cell membrane.
Are carrier proteins active or passive transport?
Carrier proteins facilitate active transport by moving molecules or ions across a cell membrane against their concentration gradient. They require energy in the form of ATP to transport substances across the membrane.
