Active transport requires energy, unlike passive transport. The carrier proteins in active transport act as a "pump" ( fueled by ATP) to carry/attach themselfves to useful proteins for the cell.

What kind of transport is involved when water molecules flow into a more concentrated glucose solution?
Diffusion is the name of this process.
What kind of particles are moved in endocytosis?
because endocytosis is an active transport process by which large particles enter a cell.
Transcripts are actually what kind of molecules?
dna molecules
What kind of molecules are transcripts?
DNA Molecules
What kind of molecules can move across the membrane For simple diffusion?
Passive transport is dependent on the permeability of the cell membrane, which, in turn, is dependent on the organization and characteristics of the membrane lipids and proteins. The four main kinds of passive transport are diffusion, facilitated diffusion, filtration and osmosis.Simple diffusion is the unassisted passage of small, hydrophobic, nonpolar molecules.
How are glucose molecules moved into a cell and what kind of transport is this?
by diffusion and passive transportation
What kind of transport require energy?
Active Transport
Which kind of cell transport needs energy?
Active transport.
How do nutrients first enter a cell?
nutrient are broken down before entering the cell.small parts of nutrients are taken inside a cell be diffusion and passive transport. there is no energy usage this kind of transport. but there are some big molecules that can not enter cell membrane. so there are taken by active transport.(there is a energy usage in active transport).
How does endocytosis differ from active transport?
Active transport utilizes transport proteins within the cellular membrane. Endocytosis occurs through an envagination of the cellular membrane itself to form a vessicle. Active transport is for transporting small molecules in and out of the cell while endo and exocytosis are for transporting large molecules in and out of the cell.
What kind of transport needs energy?
active transport requires energy from the cell
Is filtration active or passive?
its a kind of passive transport.
What kind of energy is used for cellular respirtion?
active transport
What are the different kind of cell transfort?
Active transport Passive transport (diffusion and transport using protein channels) Receptor mediated transport
What kind of molecule is used to transport molecules across the membrane?
hydropolactive.
What membrane activities require energy from ATP?
Any kind of active transport.
What kind of passive transport happens when molecules move from a area where there more molecules to an area where there are fewer?
Diffusion is the word you're looking for.
