Active transport requires energy (ATP, GTP, etc) to work against the electrochemical gradient.
Passive transport works with the electrochemical gradient and does not require energy. (Think diffusion)
Secondary active transport uses the energy stored in ion concentration gradients to transport substances across a cell membrane against their concentration gradient. This process is carried out through the coupling of the movement of one substance down its concentration gradient, with the movement of another substance against its concentration gradient. Examples of secondary active transport systems include the sodium-glucose symporter and the sodium-calcium exchanger.
Facilitated diffusion is a form of passive transport, in Facilitated diffusion molecules move across a semi-permeable membrane with the aid of specialized transports proteins and in active transport molecules move across the plasma membrane with the expenditure of ATP.
The difference between primary and secondary transport is whether the transporter directly or indirectly uses energy Primary active transport: ATP is used directly, and the energy comes from the breakage of a high energy phosphate bond. Secondary active transport: ATP is not used directly, and the energy comes from a gradient that was created by a primary active transport system that used ATP.
Primary active transport directly uses ATP by hydrolysis
Secondary transport uses an electrochemical gradient across a membrane initiated by primary active transport.
Primary active transport is the process in which ions are moved across cell membranes against the electrochemical gradient using energy supplied directly be ATP. The action of the sodium-potassium pump is an important example of primary active transport.
Secondary active transport is indirectly driven by primary transport. In the sodium-potassium pump, by pumping against the gradient, energy is stored in the ion gradient. Then, just as water pumped uphill can do the work as it flows back down, (think water wheel or turbine), a substance pumped across the membrane can do work as it leaks back, propelled downhill along the concentration gradient.
1\ In primary active process:
It required energy (ATP) to move the solute up the concentration gradient.
***
2\ In secondary active process:
It required no energy.. But instead, it needs:
- co-transport: that both molecules are on the same side and move together to other side of membrane.
- counter-transport : that both molecules are on the opposite side and move on opposite direction to each other.

Movement of a substance that utilizes a carrier, and has a concentration gradient as the source of energy.
The primary difference is that in active transport, energy is used.

What does secondary active transport do?
active
Is energy used in secondary active transport?
Yes, any form of active transport uses energy.
Is glucose molecule passive or active transport?
Secondary active transport aka facilitated diffusion [depending on your teacher].
Does Secondary active transport reabsorbs glucose and amino acid?
yes
What types of cell transport do expend energy?
Active transport processes, such as primary active transport, secondary active transport, and vesicular transport, require the cell to expend energy in the form of ATP. These processes enable the movement of molecules or ions against their concentration gradients or across membranes.
Differences between primary and secondary active transport?
In primary active transport, the transport protein gets phosphorylated; in secondary active transport, the transport protein is not phosphorylated
What does secondary active transport do?
active
What are Vesicle mediated transport is a type of?
facilitated diffusion, secondary active transport and active transport
What is secondary active transport?
yes
Is energy used in secondary active transport?
Yes, any form of active transport uses energy.
Where are tripeptides absorbed?
By secondary active transport with Hydrogen.

secondary active transport
Does Secondary active transport reabsorbs glucose and amino acid?
yes
Lactose uptake in E coli is an example of which type of transport?
it's an example of secondary active transport.
Describe the two methods of active transport?
Active transport involves the movement of molecules against their concentration gradient, requiring energy input. Two methods of active transport include primary active transport, where energy from ATP is directly used to move molecules, and secondary active transport, where the movement of one molecule down its gradient provides energy to transport another molecule against its gradient.
All transport through the cell membrane can be classified as?
passive or active transport. Passive transport does not require energy input and includes processes like diffusion and facilitated diffusion. Active transport requires energy input and includes processes like primary active transport and secondary active transport.
