What else can I help you with?
Does faciliated diffusion require energy?
Facilitated diffusion does not require energy because it relies on the use of carrier proteins to transport molecules across a cell membrane down their concentration gradient. These carrier proteins facilitate the movement of specific molecules such as glucose or ions without the need for ATP or energy input.
What is the main energy carrier in the cell?
The molecule adenosine triphosphate, or ATP, is the energy carrier of the cell.
Do large proteins containing a nuclear localization signal bind to the nuclear pore and enter the nucleus without any expenditure of energy?
No, proteins with a nuclear localization signal require energy to actively transport through the nuclear pore complex into the nucleus. They are not able to enter the nucleus passively. The binding and translocation through the nuclear pore are facilitated by specific transport receptors and require energy in the form of GTP hydrolysis.
What is the reaction that requires direct energy of sunlight to make energy carrier molecules?
Photosynthesis is the reaction that requires direct energy from sunlight to produce energy carrier molecules like ATP and NADPH in plants.
What energy carrier is produced during glycolysis?
There are a few energy carrier produced during Glycolysis but NADH and ATP are most produced.
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.
Carrier proteins do not require energy to transport amino acids into a cell?
Carrier proteins facilitate the movement of amino acids across the cell membrane through facilitated diffusion, which does not require energy input. This process relies on the concentration gradient of amino acids across the membrane.
Does faciliated diffusion require energy?
Facilitated diffusion does not require energy because it relies on the use of carrier proteins to transport molecules across a cell membrane down their concentration gradient. These carrier proteins facilitate the movement of specific molecules such as glucose or ions without the need for ATP or energy input.
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.
What is used in facilitated diffusion to assist transport of sugar and sodium molecules?
transport proteins both are carrier proteins and channel proteins
What process changes the shape of transport proteins when a particle binds with it?
The process that changes the shape of transport proteins when a particle binds to it is called conformational change. This change in shape allows the protein to either open a channel for the particle to pass through or undergo a rotational movement to transfer the particle across the membrane.
What are a series of carrier proteins?
Active transport involves carrier proteins. Carrier proteins bind themselves to particles and transport them to highly concentrated areas within a cell.Facilitated diffusion and active transport require carrier proteins.
Why is energy required for facilitated diffusion?
because those that can't get through the membrane by themselves can get help. transport proteins give them a ride through the membrane. different transport proteins make it easier for certain molecules to get through the membrane without cell using energy
How do carrier proteins facilitate the passive transport of molecules across a membrane?
Carrier proteins facilitate the passive transport of molecules across a membrane by binding to specific molecules on one side of the membrane and changing shape to transport the molecules across to the other side. This process does not require energy and is driven by the concentration gradient of the molecules.
What is the process by which molecules such as glucose are moved into cells along their concentration gradient with the help of membrane bound carrier proteins called?
The process by which molecules such as glucose are moved into cells along their concentration gradient with the help of membrane bound carrier proteins is called facilitated diffusion. Facilitated transport is passive and does not directly require chemical energy from ATP.
Facilitated diffusion moves large molecules through?
Facilitated diffusion moves large molecules through cell membranes with the help of specific carrier proteins. These proteins create channels in the membrane that allow large molecules to pass through and reach the inside of the cell. The process does not require energy input, as it relies on the concentration gradient of the molecules to drive their movement.
What describes a way proteins behave in a facilitated diffusion?
In facilitated diffusion, proteins called carrier proteins or channel proteins help facilitate the movement of specific molecules across the cell membrane. These proteins act as gates or tunnels that allow the molecules to pass through the membrane, but the process does not require energy as it follows the concentration gradient.
