What transport methods require energy expenditure by the cell?
Active transport mechanisms, such as sodium-potassium pumps, proton pumps, and endocytosis/exocytosis, require energy expenditure by the cell in the form of ATP. These processes involve the movement of substances against their concentration gradient, from an area of lower concentration to an area of higher concentration, which requires energy input.
What are the two general types of transport used by cells to transport materials in and out of the cell?
The two general types of transport used by cells are passive transport, which does not require energy and includes processes like diffusion and osmosis, and active transport, which requires energy and involves processes like protein pumps and vesicle transport.
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.
A transport process that does not require the expenditure of cellular energy is?
Passive transport... the opposite of active transport.

What is the general term for cell transport that doesn't require energy?
This type of transport is generally called passive transport.

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.
