Energy
A secondary active transporter. An example is Na+/glucose transporter. It has to move the glucose in but uses the sodium gradient to push it in instead of directly using ATP.Na gradient was made with Na/K ATPase which uses ATP (therefore it is called primary active transporter). In secondary active transport one molecule must have a higher gradient and uses ATP indirectly.
In active transport the ATP is used to pump molecules up the concentration gradient. Transport of molecules occurs from a low concentration of solute to high concentration of solute and requires cellular energy. While passive transport involves carriers, channels, or direct diffusion through a membrane.
Energy is used in active transport, where molecules are moved against their concentration gradient with the help of proteins in the cell membrane. In contrast, diffusion and osmosis are passive processes that do not require energy as molecules move from an area of higher concentration to an area of lower concentration.
Osmosis and active transport are both mechanisms used by cells to transport molecules across the cell membrane. However, osmosis is a passive process driven by the concentration gradient, while active transport requires energy to move molecules against a concentration gradient. Both processes are essential for maintaining proper cell function and regulating the movement of substances in and out of the cell.
Bulk Transport is an example of active transport. The process by which amoeba engulfs its food and secretes is a type of active transport. Amoeba forms false feet like pseudopodia and engulf food.Active and Passive transport both are related with plasma membrane. Active Transport is the transport of food across plasma membrane with expenditure of energy.
Carrier proteins are sometimes used during passive transport.

Transport proteins such as ion channels and carrier proteins are used in both active and passive transport processes. Ion channels move ions down their concentration gradient through passive transport, while carrier proteins can facilitate passive transport by allowing molecules to move along their concentration gradient, or active transport by requiring energy to transport molecules against their concentration gradient.
Active transport uses energy in the form of ATP. Active can force electrons against the electron gradient as in the electron transport chain. Passive transport does not use energy and an example of passive transpost is osmosis.

The two general types of transport used by cells are passive transport, which does not require energy and includes processes like diffusion and osmosis, and active transport, which requires energy and involves processes like protein pumps and vesicle transport.
The term "equilibrium" is used with passive transport because it describes a state where there is no net movement of molecules across a membrane due to equal concentration on both sides. In active transport, energy is used to move molecules against their concentration gradient, so equilibrium is not reached as the process continues to pump molecules in or out of the cell.
ATP is often used as the source of energy during active transport.
Carrier proteins can use active or passive transport depending on what type of carrier protein it is (meaning what the protein transports). The form of passive transport that they use is facilitated diffusion. An example of active transport is the Sodium Potassium pump. Active transport requires ATP. Facilitated diffusion is used to transport polar molecules and ions that cannot directly cross the cell membrane. Facilitated diffusion doesn't require energy.
