Passive ways of crossing the plasma membrane include diffusion and facilitated diffusion, where substances move across the membrane down their concentration gradient without the use of energy. Active transport, on the other hand, requires energy, typically in the form of ATP, to move substances against their concentration gradient. Examples of active transport include the sodium-potassium pump and endocytosis. Overall, passive transport relies on natural concentration differences, while active transport requires energy input.
What else can I help you with?
What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins
Does passive or active processes account for the movement of fats and respiratory gases through the plasma membrane?
Passive processes, such as simple diffusion and facilitated diffusion, account for the movement of fats and respiratory gases through the plasma membrane. These processes do not require energy input and rely on the concentration gradient to drive the movement of molecules across the membrane.
How is the cell membrane facilitated diffusion transported?
In Facilitated diffusion materials are transported across the plasma membrane without using up any energy. Plasma membranes is made up of phospholipid bilayers consisting of proteins which help in the transportation of larger materials.
How does nutrients cross plasma membrane?
Things like oxygen, CO2 and lipids cross the membrane with simple diffusion. Water can cross the membrane with osmosis when the water moves through a channel protein in the plasma membrane. Glucose, potassium, sodium etc. moves through a carrier protein in the membrane with the process of active movement. In the process of active movement energy is needed and it is given by the glucose or ATP from the cell.
Why is the plasma membrane called the selectively permeable membrane?
Let trans-membrane transport of molecules be either passive, or facilitated, or active: the plasma [bi-lipid layer] membrane has the power to exclude molecules It selects from passage through the Membrane into the Cell's interior.
What is the difference between passive and active transport across the plasma membrane?
Active transport is ATP dependent, whereas passive transport uses only the kinetic energy of the particles for movement across the plasma membrane- mastering A and P homework-
What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins
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 or active processes account for the movement of fats and respiratory gases through the plasma membrane?
Passive processes, such as simple diffusion and facilitated diffusion, account for the movement of fats and respiratory gases through the plasma membrane. These processes do not require energy input and rely on the concentration gradient to drive the movement of molecules across the membrane.
Carrier molecules in the plasma membrane are only required for active transport?
Carrier molecules in the plasma membrane are actually used for both active and passive transport of molecules. In active transport, carrier proteins use energy to move molecules against their concentration gradient, while in passive transport, carrier proteins facilitate the movement of molecules down their concentration gradient without the need for energy input.
Is osmosis of active transport or passive transport?
Osmosis does not require ATP so it is a passive transport.Osmosis is a form of passive transport. Water molecules are small enough to move freely across the plasma membrane without the use of cellular energy.

What organelle is involved in passive transport in both plant and animal?
the plasma membrane.

What is net movement of substances across plasma membrane without additional energy?
Diffusion. With the need of energy, it would be called active transport.
What is this method of molecular transport is called?
Molecular Transport (in cells) is the movement of materials across a cell membrane. The two kinds of Molecular Transport used in organisms are Active Transport and Passive Transport. Active Transport- materials move across the plasma membrane with the use of energy (like Adenosine Triphosphate) Passive Transport- materials move accross the plasma membrane without the use of energy
