What is the different between active transport and passive transport of molecules across the cell membrane?
In an active transport, the cell uses energy (ATP) to transport the particle into the cell. Also, the particle moves through a "hallway" type thing. In a passive transport, the cell does not need energy (ATP) to transport the particle into the cell. Also, the particle just bursts through the cell membrane to get inside.
What is large particles that may need to use energy to pass through cell membranes called?
Large particles that require energy to pass through cell membranes are called active transport. This process involves the movement of molecules or ions against their concentration gradient with the help of specialized proteins called pumps. Examples include the sodium-potassium pump and endocytosis.
What transport may need to use energy to pass through cell membrane?
active transport
What process transports particles that move through cell membrane between phospholipid molecules?
The process that transports particles through the cell membrane between phospholipid molecules is called passive diffusion. In passive diffusion, particles move from an area of higher concentration to an area of lower concentration without the need for energy input.
What is the active transport and passive transport?
The requirements of passive transport through the cell membrane (phospholipid bilayer) of an animal cell are that the molecule is non-polar or small enough to pass by the non-polar phospholipid tails. This is because, for there to be passive transport, no energy must be used to transport the molecule from outside of the cell to inside.
What a cell need to transport particles by active transport?
Energy

What structures allow small particles to cross the cell membrane?
Small particles can cross the cell membrane through simple diffusion, facilitated diffusion, or active transport. In simple diffusion, particles move from an area of high concentration to low concentration without the need for energy. Facilitated diffusion involves the use of protein channels or carriers to aid in the movement of particles. Active transport requires energy and transport proteins to move particles against their concentration gradient.
Does glucose need a transport protein?
Depends if it goes into the cell or out of the cell whether it is passive or active. Yes.
What process transports particles that move through cell membrane between phospholipid molecules?
The process that transports particles through the cell membrane between phospholipid molecules is called passive diffusion. In passive diffusion, particles move from an area of higher concentration to an area of lower concentration without the need for energy input.
What type of transport supplies a cell with glucose?
thanks to: Bobama 08. question: what transport supplies a cell with glucose? answer: The passive transport supplies a cell with glucose. A passive transport is the diffusion of particles through the proteins. The particles move from an area of high concentration to an area of low concentration. The cell does not need to use any energy to make this happen. Whereas, an active transport is the movement of particles through proteins against the normal direction of diffusion. Particles are moved from an area of low concentration to an area of high concentration. The cell must use energy to make this happen. This energy comes from the molecule ATP, which stores energy in a form that cells can use. Therefore, the passive cell transport supplies a cell with glucose.
How does diffusion from active transport?
Active transport expends energy, unlike osmosis and diffusion. Active transport is a way to move substances against concentration gradients in the cell membrane, so they need more energy to do so.
Does simple diffusion require transport proteins?
No, simple diffusion does not require transport proteins. It is a passive process where molecules move from an area of higher concentration to an area of lower concentration directly through the lipid bilayer of the cell membrane. Transport proteins are involved in facilitated diffusion and active transport.
The movement of substances across the cell membrane that requires the cell to use energy?
It's called active transport. When talking about the cell, it is usually bigger substances that use passages in the cell membrane to access the inner part of the cell, and they need energy to get there. The opposite; passive transport or diffusion, is the movement of dissolved materials through a cell membrane without the use of cellular energy. THis happens with smaller substances.
Why would a cell need active transport?
A cell would need active transport to move molecules against their concentration gradient or to move large molecules or ions across the cell membrane. This process requires energy in the form of ATP to power protein pumps that facilitate the transport. Active transport is essential for maintaining proper cellular functions and homeostasis.
