Cells need organelles such as ATP-powered pumps, transport proteins, and vesicles for active transport to occur. These organelles help in moving molecules and ions across the cell membrane against their concentration gradient, requiring energy input. Active transport is essential for maintaining proper cellular function and homeostasis.
What else can I help you with?
What cellular function is missing in dead cells Osmosis Diffusion Active transport (solute pumping) or dialysis?
The cellular function that is missing in dead cells is active transport (solute pumping). Active transport requires energy to move molecules against their concentration gradient, a process that cannot occur if the cell is no longer metabolically active. Osmosis, diffusion, and dialysis can still occur in dead cells as they do not require energy expenditure by the cell.
Which type of transport could not occur if the cell was inhibited in the production of protein?
Active transport would not be able to occur if the cell was inhibited in the production of proteins. Active transport relies on specific proteins, such as pumps and carriers, to move molecules against their concentration gradient. Without these proteins, the cell would not be able to perform active transport.
Where does active transport occur i plants?
Active transport in plants occurs mainly in the root cells, where the uptake of essential nutrients from the soil takes place. This process requires energy to move molecules against their concentration gradient, ensuring that plants can absorb the necessary nutrients for growth and development.
Does active transport require water?
No.... The Active Transport Requires Energy >> Just Energy But Our Bodies Transport a lot Of Substances Using Active Transport Including Water , Metal Ions, etc .......
What are two ways active transport differs from passive transport?
Active transport is when cells use energy to move things through a cell membrane.Passive transport is when the cell uses no energy to move materials.Active - Specifically uses energy and through a cell membranePassive - Specifically uses no energy and materials

Does endocytosis occur in prokaryotes?
Yes, endocytosis does not occur in prokaryotes because they lack membrane-bound organelles and do not perform phagocytosis, pinocytosis, or receptor-mediated endocytosis like eukaryotic cells. Instead, prokaryotes rely on other mechanisms such as simple diffusion, facilitated diffusion, and active transport to take in nutrients and molecules.
What substances used to help active transport occur within cells?
Proteins are major substances involved in active transport within cells. Examples include ion pumps like Na+/K+ ATPase and transporters like glucose transporters. ATP provides the energy needed for these proteins to actively transport molecules across the cell membrane.

Active transport would not be able to occur if the cell was inhibited in the production of proteins. Active transport relies on specific proteins, such as pumps and carriers, to move molecules against their concentration gradient.

Where does gylcolysis occur?
In the cytoplasm (the goop in that fills cells outside of the organelles).
Having membrane covered organelles a characteristic of what cells?
Eukaryotic cells have membrane-covered organelles, which compartmentalize cellular functions and allow for more complex and specialized processes to occur. This distinguishes them from prokaryotic cells, which lack membrane-bound organelles.
When reffering to molecular transport does movement occur across the cell membrane?
yes, it can occur in various ways. (active transport, simple diffusion,etc.)
What is the defference between active transpors and passive transport?
Active transport requires energy input to move molecules against their concentration gradient, while passive transport moves molecules along their concentration gradient without energy input. Active transport is typically carried out by transport proteins, such as pumps, while passive transport can occur through simple diffusion or facilitated diffusion.
What is needed to to facilitate diffusion and active transport?
ATP is needed for these two transport mechanisms to occur.

Is channel-mediated diffusion a form of active transport?
Yes, when channels are specific for the structures of individual molecules it is active transport. Active transport cannot occur if the energy they are moving is not of the same type, like glucose cannot move calcium.
