What is a general type of transport that does not require an expenditure of energy by the cell?
Passive transport is a general type of transport that does not require an expenditure of energy by the cell. This type of transport relies on the natural movement of molecules from an area of higher concentration to an area of lower concentration, such as diffusion or osmosis.
Which transport does not require cell energy?
Diffusion is per definition a passive transport process.
A type of transport across a membrane up its concentration gradient using protein carriers and driven by the expenditure of chemical energy is known as what?
This is a description of active transport.
Does facilitated diffusion require energy to transport molecules across the cell membrane?
Facilitated diffusion does not require energy to transport molecules across the cell membrane.
Describe the two methods of active transport?
Active transport involves the movement of molecules against their concentration gradient, requiring energy input. Two methods of active transport include primary active transport, where energy from ATP is directly used to move molecules, and secondary active transport, where the movement of one molecule down its gradient provides energy to transport another molecule against its gradient.
A transport process that does not require the expenditure of cellular energy is?
Passive transport... the opposite of active transport.

what two methods of transport require a transport protein?
Two methods of transport that require a transport protein are facilitated diffusion and active transport. Facilitated diffusion involves the movement of molecules across a cell membrane through specific transport proteins, down their concentration gradient without the use of energy. Active transport, on the other hand, uses transport proteins to move substances against their concentration gradient, requiring energy in the form of ATP.
Distinguish between active and passive transport?
Active Transport is the passage of materials across the membrane through the expenditure of energy. Passive Transport is the passage of materials across the membrane without the expenditure of energy. Bulk Transport is the type of active transport. Diffusion and Osmosis are type of passive transport.
What kind of transport require energy?
Active Transport
Why do elderly require less energy?
They require less energy as they do not do much work compared to teenagers. They should have less energy intake and less energy expenditure.
What produces energy from the passive transport?
nothing, passive transport doesn't require energy
What is the name of the process of how things get in and out of the cell?
The process by which substances enter and exit the cell is called cellular transport. It primarily occurs through two main mechanisms: passive transport, which does not require energy, and active transport, which requires energy expenditure by the cell. Examples of passive transport include diffusion and osmosis, while examples of active transport include endocytosis and exocytosis.
Does not require such an energy expenditure and occurs spontaneously?
The process you are describing is "passive transport," which moves substances across a cell membrane without the need for energy input. This can occur through processes like diffusion and osmosis, driven by concentration gradients.
Why do plants use passive transport?
Plants use passive transport because it does not require energy expenditure. Passive transport mechanisms like diffusion and osmosis allow plants to move water, nutrients, and gases across their cell membranes based on concentration gradients. This is an efficient way for plants to absorb essential resources from their environment.
Active transport require energy?
Yes it does.
What does active transport require the use of?
Energy
