Cells need active transport to regulate their internal environment. The ability of a cell to regulate its internal environment is important because it allows the cell to add substrates to reactions that are necessary for life.
Primary active transport (the movement of molecules against their electrochemical gradient) helps to power secondary active transport (or co-transport) which is the transport of an ion/molecule against its electrochemical gradient, in company with an ion/molecule being transported with its electrochemical gradient.

∙ 14y agoActive transport requires the expenditure of energy by the cells. It is an uphill movement of a substance through a living cell membrane. Adenosine triphosphate or ATP is a chemical substance that gives the energy required for the active transport process. ATP is produced in the mitochondria using energy from nutrients and is capable of releasing that energy to do work in the cell. There is a breakdown of APT and a use of energy that makes this process possible. Cellular energy is required to move substances from a low concentration to a high concentration. Because the formation and breakdown of ATP requires complex cellular activity, active transport mechanisms can take place only through living membranes.

A form of passive transport that uses transport proteins-?
Diffusion (passive transport) needs no energy to take place, and therefore no need for transport or carrier protiens. Active transport uses carrier protiens, as the cell needs to work against a concentration gradient. This requires energy. Diffusion can take place outside of cells Active transport can't take place outside of cells.
Could an organism survive only by using passive transport never active transport?
There's an almost infinite number of organisms out there and I wouldn't be overly surprised if some could, but generally speaking, cells need active transport to maintain control over the substances entering and exiting. At the expense of some enrgy, active transport allows cells to control to some extent the molecules that are allowed to cross the plasma membrane. A basic example would be to say that in most human cells, waste products are secreted by active transport so without such a process there would be a toxic buildup in the cell; and also that glucose requires active transport to enter a cell so without it, the cell would have no form of energy and die
What cells need more respiration?
Cells that need more respiration typically include those that are highly active and require lots of energy. Examples of these cells include: Cells in muscle tissue Brain cells Cells in the heart Cells in the lining of the small intestineThese cells require more respiration in order to produce the energy they need to perform their intended functions.
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.
How is active transport different from possive transport?
Active transport need energy from outside to perform a function whereas in passive transport the function is performed on the principle of physics. for example active absorption of minerals by the plant roots require energy from respiration whereas passive absorption is achieved by law of diffusion.
Why do cells need to use active transport?
This energy comes from the molecule ATP,which stores energy in a form that cells can use
How is facilitated transport different from active transport?
Facilated transport does not need to use energy but active transport does.
Does exocytosis need to expend energy to perform?
Yes , Exocytosis is a part of active transport meaning it needs energy to move from concentration gradients.
What a cell need to transport particles by active transport?
Energy
What does a cell need to transport particles by active transport?
Energy
What do cells that secrete large amounts of substances via active transport need a large amount of in their cytoplasm?
Mitochondria for ATP(energy)

The different between passive transport and active transport?
Active transport requires energy; passive transport does not.
What type of transport needs energy?
Active transport needs energy, passive transport does not need energy.
