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
What is the process called when cells have to use energy to move materials through the cell membrane?
The answer you are looking for is 'active transport'. Here the cell moves the molecule into (or out of) the cell against the concentration gradient. This requires energy. There are other energetic process such as endo- and exo-cytosis that the cell uses to move large molecules.
Which type of membrane transport process uses ATP as a source of energy?
Active transport uses ATP as an energy source.
How do substances get in and out of a cell if they are to big to pass through the cell membrane?
Do you mean how do substances move through a cell membrane if they are too big to transport by passive transport?If so, a cell uses active transport to move large particles in and out of a cell. Active transport includes endocytosis, pinocytosis, and phagocytosis.
A kidney cell uses chemical energy to pump salt from an area of low concentration to an area of high concentration in order to excrete it what is this an example of?
Active transport
Is an example of active transport?
An example of active transport is sugar molecules going into a cell. It cannot pass right through like water and oxygen so it uses active transport.Diffusion

Is pinocytosis acitve or passive transport?
It is the active transport of liquids in vesicles into and out of a cell so it uses metabolic energy, thus active

When a cell uses energy to transport a particle through the cell membrane to an of higher concentration the cell is using?
Active transport
If the substance entering the cell was in higher concentration inside the cell then outside the cell what type of transport would be required?
It would be active transport, a process which requires a cell to use its own energy (unlike passive transport).
What uses protein binds to a particle and uses energy to move through the cell membrane?
active transport

What is the different between active transport and passive transport of molecules across the cell membrane?
In an active transport, the cell uses energy (ATP) to transport the particle into the cell. Also, the particle moves through a "hallway" type thing. In a passive transport, the cell does not need energy (ATP) to transport the particle into the cell. Also, the particle just bursts through the cell membrane to get inside.
Which type of membrane transport process uses ATP as a source of energy?
Active transport uses ATP as an energy source.
Is diffusion part of an active transport?
No, diffusion is where particles flow in order to be equal, whereas active transport uses ATP to move them through a cell membrane.
