Which means of participle transport requires input of energy from the cell?
Active transport requires an input of energy from the cell. Unlike passive transport, which relies on concentration gradients, active transport moves substances against their concentration gradient, often utilizing ATP to power transport proteins. This process is crucial for maintaining cellular homeostasis and enabling the uptake of essential nutrients.
What type of transport do cells utilize?
Cells utilize various types of transport mechanisms to move substances across their membranes, including passive transport, active transport, and vesicular transport. Passive transport, such as diffusion and osmosis, does not require energy and relies on concentration gradients. Active transport requires energy to move substances against their concentration gradients. Vesicular transport involves the formation of vesicles to transport large molecules or particles into (endocytosis) or out of (exocytosis) the cell.
What are active and passive transport and how they are alike and different?
Active transport and passive transport are two methods by which substances move across cell membranes. Active transport requires energy, typically in the form of ATP, to move molecules against their concentration gradient, while passive transport does not require energy and occurs along the concentration gradient. Both processes are essential for maintaining cellular homeostasis, but they differ in their energy requirements and the direction in which substances move relative to their concentration gradients.
Does active transport move from higher to lower concentration?
Active Transport- When molecules move from an area of lower concentration to an area of higher concentrationPassive Transport- When molecules move from an area of higher concentration ot an area of higher concentration (also called diffusion)
What process does not take material into cells?
The process that does not take material into cells is known as passive transport. This includes mechanisms like diffusion and osmosis, where substances move across cell membranes along their concentration gradients without the need for energy input. Unlike active transport, which requires energy to move materials against their concentration gradient, passive transport allows molecules to passively flow into or out of cells based on existing concentration differences.
What is the pumping of materials across a membrane against their concentration gradients?
Active Transport
Which process uses proteins to move molecules against a concentration gradients?
active transport
Why would a cell need active transport?
A cell would need active transport to move molecules against their concentration gradient or to move large molecules or ions across the cell membrane. This process requires energy in the form of ATP to power protein pumps that facilitate the transport. Active transport is essential for maintaining proper cellular functions and homeostasis.

How does active transport differ from diffusion?
Active transport expends energy, unlike osmosis and diffusion. Active transport is a way to move substances against concentration gradients in the cell membrane, so they need more energy to do so.
Does active transport move molecules against their concentration gradients?
Yes, active transport is a cellular process that moves molecules against their concentration gradients, requiring energy in the form of ATP to pump substances across the cell membrane. This process allows cells to accumulate molecules or ions at concentrations higher than their surroundings, enabling them to maintain internal balance and perform essential functions such as nutrient uptake and waste removal.
What means of particle transport requires input of energy in a cell?
Active transport is a means of particle transport that requires the input of energy in a cell. This transport mechanism moves substances against their concentration gradient, from an area of lower concentration to an area of higher concentration, requiring energy to drive the process.
Proceeds Against a concentration Gradient requires a carrier?
Yes, the movement of molecules against a concentration gradient requires the use of a carrier protein or active transport mechanism in order to transport the molecules from an area of lower concentration to an area of higher concentration. This process requires energy to move molecules against their natural gradient.
Active transport differs from facilitated diffusion because active transport 1 Works against conc.giadent 2 employs specific carrier molecules 3 transports H2O 4 depends on hydrostatic pressure?
Active transport works against concentration gradients, employs specific carrier molecules, and requires energy input in the form of ATP. Facilitated diffusion, on the other hand, does not require energy input and utilizes carrier proteins to transport molecules down their concentration gradient.
Why active transport requires energy?
Active transport requires energy because it moves molecules or ions against their concentration gradient, from areas of lower concentration to areas of higher concentration. This process goes against the natural tendency of molecules to diffuse down their concentration gradient, requiring the input of energy in the form of ATP to drive the transport proteins involved.
