What are the three forms of passive transport and how do they differ in their mechanisms of movement across the cell membrane?
The three forms of passive transport are diffusion, facilitated diffusion, and osmosis. Diffusion involves the movement of molecules from an area of high concentration to an area of low concentration. Facilitated diffusion uses protein channels to help molecules move across the membrane. Osmosis is the movement of water molecules across a selectively permeable membrane.
What else can I help you with?
Does passive transport require ATP for the movement of molecules across the cell membrane?
No, passive transport does not require ATP for the movement of molecules across the cell membrane.
What is it called when the movement of materials through a cell membrane without using the cells energy?
Passive transport does not use energy to pass through a cell membrane. active transport uses energy to pass through a cell membrane.
The movement of substances through a cell membrane without the use of cell energy?
Passive transport using osmosis and diffusion. Osmosis only applies to the movement of water down a concentration gradient across a selectively permeable membrane. DOH!!!
What types of transport mechanisms through the cell membrane are passive?
diffusion, facilitated diffusion, and osmosis
What is the name of the membrane that allows the movement of water and substances to move through the process of active transport and passive transport?
The cell membrane, also known as the plasma membrane, is responsible for regulating the movement of water and substances through processes like active transport and passive transport. It acts as a selectively permeable barrier, allowing certain molecules to pass through while blocking others.
Does passive transport require ATP for the movement of molecules across the cell membrane?
No, passive transport does not require ATP for the movement of molecules across the cell membrane.

Passive transport using osmosis and diffusion. Osmosis only applies to the movement of water down a concentration gradient across a selectively permeable membrane. DOH!!!
Is water an active or passive transport?
Water can use both passive and active transport mechanisms. Passive transport involves movement of water molecules across a membrane without the need for energy, while active transport involves the use of energy to move water molecules against their concentration gradient.
The movement of materials through a cell membrane without using the cells energy?
It's called passive transport for a cell's membrane. (I checked with my science teacher)
A sentence for the word passive transport?
Passive transport refers to the movement of molecules across a cell membrane. An example of a sentence would be: "Passive transport does not require energy to work".
What is the movement of materials through a cell membrane?
Movement of substances into and out of cells include passive mechanisms that do not require cellular energy (diffusion, facilitated diffusion, osmosis, and filtration) and active mechanisms that use cellular energy (active transport, endocytosis,and exocytosis).
What types of transport mechanisms through the cell membrane are passive?
diffusion, facilitated diffusion, and osmosis
What is the name of the membrane that allows the movement of water and substances to move through the process of active transport and passive transport?
The cell membrane, also known as the plasma membrane, is responsible for regulating the movement of water and substances through processes like active transport and passive transport. It acts as a selectively permeable barrier, allowing certain molecules to pass through while blocking others.
How does passive diffusion differ from facilitated diffusion in terms of their mechanisms of transport?
Passive diffusion and facilitated diffusion both involve the movement of molecules across a cell membrane, but they differ in their mechanisms of transport. Passive diffusion does not require the assistance of transport proteins and relies on the natural movement of molecules from an area of high concentration to an area of low concentration. Facilitated diffusion, on the other hand, involves the use of specific transport proteins to help molecules move across the membrane, typically from an area of high concentration to an area of low concentration. In summary, passive diffusion is a simple process driven by concentration gradients, while facilitated diffusion involves the assistance of transport proteins for more efficient movement of molecules.
How is passive transport from active transport?
The movement of materials across the cell membrane without using cellular energy is called passive transport. The movement of materials against a concentration difference is known as active transport. Active transport requires energy.
Is a primary transport the passive movement of large particles across the membrane?
No, primary transport involves the active movement of ions or molecules across a membrane against their concentration gradient, using energy typically derived from ATP. In contrast, the passive movement of large particles across the membrane is known as facilitated diffusion, which does not require energy and occurs through specific transport proteins. Thus, primary transport is an active process, while passive movement relies on concentration gradients.
