For active transport to occur, energy is needed in the form of ATP. During respiration energy is released in the form of ATP
The reason why energy (ATP) is needed with active transport is because active transport is movement of molecules from a low concentration to a high concentration so its going againstthe concentration gradient. As its going against the concentration, energy (in the form of ATP) is necessary or else this process will not occur.

Active transport always requires transport proteins during the process?
false

What is the difference between passive and active transport across the cell membrane?
Wouldn't it be that active transport requires enegry and passive doesn't? Passive transport occurs when the concentration of something on one side of membrane is different from the concentration on the other side. It occurs when that substance can pass through the membrane, and always in the direction of more -> less. No energy is required to make the substance move; in fact, this movement generates energy. This is like rolling a rock down a hill--it just does it on its own. Active transport occurs in the opposite direction, from less -> more. It requires energy for transport. This is like rolling a rock up a hill--you have to push it the entire way! Both involve the transport of a substance across a membrane, and the change in concentrations on different sides of a membrane. Both are also important to the proper functioning of a cell. Active transport requires energy, but passive transport requires none. Active transport requires a special protein to make the transport occur, but passive transport requires none.
The transport of molecules of a particular solute from inside an animal cell across the cell membrane to the extracellular fluid always requires energy when?
The transport of molecules of a particular solute from inside an animal cell across the cell membrane to the extracellular fluid always requires energy when it is against the concentration gradient, a process known as active transport. Energy is needed to move the molecules from an area of low concentration to an area of high concentration.
What two characteristics describe active transport?
Two characteristics that describe active transport are that active transport: -require energy -always maintain effervescence, which is the the state in which molecules move from a lower concentration to a higher one.

What transport processes always requires metabolic energy?
Vesicular transport
What is the different between passive and active transport?
One difference is energy consumption. Active transport requires the cell to expend energy, while passive transport does not. Active transport is movement from a lower concentration to a higher concentration and passive transport is movement from a higher concentration to a lower concentration. Active transport is the movement of molecules across a membrane requiring energy to be expended by the cell. Passive transport is diffusion across a membrane requiring only random motion of molecules with no energy expanded by the cell. Active transport requires ATP to transport materials. Passive transport does not require ATP input to transport materials. Ex: diffusion

During active transport substances move from regions of what?
in active transport, where do molecules always go
Is the following sentence true or false active transport always requiring transport proteins during the process?
false
How is the active transport different from diffusion?
The main difference is that diffusion does not require energy and active transport does require energy. Just for the record diffusion has a concentration that moves from high to low, and active transport has a concentration that moves from low to high. (Hope this helps to answer your question!)
When stuff diffuses why does it always go to a less concentrated area?
When matter diffuses through a cell it moves from an area of higher concentration to an area of lower concentration. This process is called passive transport, which requires no energy. Opposite to that, active transport requires energy, or ATP, because it is moving things from an area of lower concentration to higher.
