When does the passive transport of a molecule from the inside of a cell to the outside occur?
Passive transport of a molecule from inside a cell to the outside occurs when the molecule moves down its concentration gradient, meaning it moves from an area of higher concentration to an area of lower concentration. This process does not require energy, as it relies on the natural tendency of molecules to spread out. Common mechanisms for passive transport include diffusion and facilitated diffusion through protein channels.

What is the transport of a molecule from the inside of a cell to the outside of a cell called?
The transport of molecules from inside a cell to the outside is called exocytosis. In this process, vesicles containing the molecules fuse with the cell membrane, releasing the contents to the extracellular space.
What are passive transport active transport and endocytosis?
These are three different ways that cells have to get things in and out of the cell. Passive transport is movement without the use of energy, active transport requires energy.Active transport requires energy since the molecules are going toward a region that has a higher concentration of that molecule. The cell is 'stuffing' more into itself.Endocytosis means to 'take into the cell'. Usually this a larger molecule and cell must wrap part of itself around the molecule and then can bring it inside. This is a type of phagocytosis (cell eating).This requires energy as well.
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 happens if the concentration of glucose is higher on the outside than the inside what will happen to the process of diffusion?
If the concentration of glucose is higher outside the cell than inside, glucose will diffuse into the cell down its concentration gradient. This process occurs through passive transport, where molecules move from an area of higher concentration to an area of lower concentration. The diffusion will continue until equilibrium is reached, or until the concentration inside the cell matches that outside.
How passive and active transport are related to concentrations of the molecules inside and outside the cell?
Passive transport occurs when molecules move across a cell membrane from an area of higher concentration to an area of lower concentration without requiring energy, relying on concentration gradients. In contrast, active transport involves the movement of molecules against their concentration gradient, from an area of lower concentration to an area of higher concentration, which requires energy, typically in the form of ATP. Both processes are essential for maintaining cellular homeostasis and regulating the internal environment of the cell based on the external conditions. Thus, the concentration of molecules inside and outside the cell directly influences the direction and mechanism of transport.
When does passive transport occurs?
It occurs when there are more of that certain molecule on the outside of the cell than the inside. When this is the case, the molecule will automatically pass through the membrane without the cell using energy.
How are active and passive differ from from each other?
The most basic difference between active and passive transport is that active requires energy while passive does not. You would require active transport if the substance is going against the concentration of molecules inside and outside of the membrane or if the substance is particularly large. Passive is more for smaller molecules that go with the concentration of the molecules inside and outside of the membrane.
What is the transport of a molecule from the inside of a cell to the outside of a cell called?
The transport of molecules from inside a cell to the outside is called exocytosis. In this process, vesicles containing the molecules fuse with the cell membrane, releasing the contents to the extracellular space.
How are active transport and passive transport different from each other?
Active transport requires energy input to move substances across a membrane against their concentration gradient, while passive transport does not require energy as it moves substances along their concentration gradient. Active transport is selective and requires specific transport proteins, while passive transport occurs through simple diffusion or facilitated diffusion.
Why does it take energy to transport some things across the cell but it doesn't take energy to transport other things?
there are two ways to transport things into a cell: active and passive transport. In active transport the cell has to physical engulf whatever it needs from outside the cell. In passive transport, if something inside the cell has less of the item that is outside of the cell, the things outside of the cell go into the cell until the number is balanced. This happens automatically so it doesn't involve energy.

What are examples of passive transport and active transport?
Proteins that carry out passive transport include channel proteins and carrier proteins. Passive transport is "passive" because it does not use energy. The use of passive transport is also called "facilitated diffusion." Proteins that carry out passive transport includes the proton pump and the sodium-potassium pump; these require energy to function.
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.
If the substance entering the cell was in higher concentration inside the cell then outside the cell what type of transport would be required?
It would be active transport, a process which requires a cell to use its own energy (unlike passive transport).
What is the transport of substances from the outside to the inside of a cell by a vesicle?
Vesicular active transport
What does the cell transport include?
Cell transport includes processes like passive diffusion, facilitated diffusion, active transport, and endocytosis/exocytosis. These processes help cells regulate the movement of molecules across their membrane to maintain a balance of ions and nutrients inside and outside the cell.
Explain osmosis diffusion passive transport and active transport?
Osmosis is the diffusion of water molecules through a semi-permeable membrane. Diffusion is a passive transport that goes from a higher concentration area to a lower concentration area.Passive transport means that there is no energy required to move it.
