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 the difference between symport and antiport?
Symport is a type of membrane transport where two different molecules are transported in the same direction across a membrane, while antiport is a type of membrane transport where two different molecules are transported in opposite directions across a membrane. In symport, the molecules move in the same direction to maintain equilibrium, whereas in antiport, the molecules move in opposite directions to create a gradient.
What small membrane-bound sac is used to transport cellular chemicals?
A small membrane-bound sac used to transport cellular chemicals is called a vesicle. Vesicles help transport molecules between different cellular compartments and play a key role in maintaining cellular organization and function.
Which molecules do not normally cross the nuclear membrane?
Large molecules such as proteins and RNA do not normally cross the nuclear membrane. They require specific transport mechanisms, such as nuclear pores, to move between the nucleus and the cytoplasm. This selective transport ensures that only specific molecules can enter or exit the nucleus.
What are Vesicle-mediated transport is a type of?
Vesicle-mediated transport is a type of intracellular transport where cellular materials are moved within a cell using membrane-bound vesicles. This process allows for the transport of molecules such as proteins, lipids, and other substances between different organelles within the cell or between the cell and its external environment.
What is the vaculor that regulates movement of the materials from the cavity into and out of general cytolplasm?
The transport vesicle is the vacuole that regulates movement of materials between the cell's organelles and the cytoplasm. It helps to transport molecules such as proteins and lipids to different parts of the cell or to the cell membrane for secretion.
What is the difference between symport and antiport?
Symport is a type of membrane transport where two different molecules are transported in the same direction across a membrane, while antiport is a type of membrane transport where two different molecules are transported in opposite directions across a membrane. In symport, the molecules move in the same direction to maintain equilibrium, whereas in antiport, the molecules move in opposite directions to create a gradient.
What particles move through cell membrane between phospholipid molecules What transport?
Osmosis, Passive Transport, and Active Transport
What is the role of the basolateral membrane in the transport of molecules across epithelial cells?
The basolateral membrane in epithelial cells helps transport molecules into and out of the cell. It plays a key role in regulating the movement of substances between the cell and its surroundings.
What is the difference between an antiporter and a symporter in terms of their mechanisms of transport?
An antiporter moves two different molecules in opposite directions across a cell membrane, while a symporter moves two different molecules in the same direction.
What is the difference between active and facilitated transport in cellular processes?
Active transport requires energy to move molecules across the cell membrane, while facilitated transport uses carrier proteins to help molecules pass through the membrane without energy.
What different roles and functions do membrane proteins serve?
Membrane proteins relay signals between the cell's internal and external environments. They transport proteins and move molecules and ions across the membrane. They have many activities such as oxidoreductase, hydrolase or transferase.
What small membrane-bound sac is used to transport cellular chemicals?
A small membrane-bound sac used to transport cellular chemicals is called a vesicle. Vesicles help transport molecules between different cellular compartments and play a key role in maintaining cellular organization and function.
What are function of membrane proteins?
Membrane proteins have a variety of functions. They relay signals between the cell's inside and outside environments. Transport proteins move the molecules across the membrane.
What is the difference between a symporter and an antiporter in terms of their mechanisms of transport across cell membranes?
A symporter moves two different molecules in the same direction across a cell membrane, while an antiporter moves two different molecules in opposite directions.
What are the similarities between active transport and facilitated diffusion in terms of their mechanisms of transporting molecules across the cell membrane?
Both active transport and facilitated diffusion are mechanisms that transport molecules across the cell membrane. They both involve the movement of molecules from an area of higher concentration to an area of lower concentration. However, active transport requires energy input from the cell to move molecules against their concentration gradient, while facilitated diffusion does not require energy and relies on carrier proteins to help molecules pass through the membrane.
Which molecules do not normally cross the nuclear membrane?
Large molecules such as proteins and RNA do not normally cross the nuclear membrane. They require specific transport mechanisms, such as nuclear pores, to move between the nucleus and the cytoplasm. This selective transport ensures that only specific molecules can enter or exit the nucleus.
What is the difference between passive and active transport across the cell membrane?
Wouldn't it be that active transport requires enegry and passive doesn't? Passive transport occurs when the concentration of something on one side of membrane is different from the concentration on the other side. It occurs when that substance can pass through the membrane, and always in the direction of more -> less. No energy is required to make the substance move; in fact, this movement generates energy. This is like rolling a rock down a hill--it just does it on its own. Active transport occurs in the opposite direction, from less -> more. It requires energy for transport. This is like rolling a rock up a hill--you have to push it the entire way! Both involve the transport of a substance across a membrane, and the change in concentrations on different sides of a membrane. Both are also important to the proper functioning of a cell. Active transport requires energy, but passive transport requires none. Active transport requires a special protein to make the transport occur, but passive transport requires none.
