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.
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.
Which transport does not require cell energy?
Diffusion is per definition a passive transport process.
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.
Facilitated diffusion requires the use of cellular energy ATP expenditure?
No, facilitated diffusion does not require the use of cellular energy (ATP). It relies on membrane transport proteins to help move molecules across the cell membrane with the concentration gradient, without needing energy input from the cell.
A transport process that does not require the expenditure of cellular energy is?
Passive transport... the opposite of active transport.
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.
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.
Which cellular processes require the greater expenditure of cellular enery and uses specific carrier molecules?
Cellular processes that require a greater expenditure of energy and utilize specific carrier molecules include active transport and endocytosis. Active transport moves substances against their concentration gradient, using ATP and transport proteins like pumps. Endocytosis involves the engulfing of materials into the cell membrane, requiring energy to form vesicles. Both processes are essential for maintaining cellular homeostasis and nutrient uptake.
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.
What is the meaning of the passive transport?
The inter-membranous transport occurs in two ways: 1) Active Transport: occurs against the concentration gradient, Expenditure of energy occurs. 2) Passive transport: Refers to phenomena wherein transfer occurs along the concentration gradient i.e. from high concentration to low concentration, without any expenditure of energy.
