Passive processes do not require energy input and occur spontaneously, such as diffusion, osmosis, and facilitated diffusion. Active processes require energy input to proceed, such as active transport, endocytosis, and exocytosis to move substances against their concentration gradient.

What are the definitions of cellular transport processes?
Cellular transport processes refer to the movement of molecules across cell membranes. This includes passive processes like diffusion and facilitated diffusion, as well as active processes like active transport and endocytosis/exocytosis. These processes are crucial for maintaining cellular homeostasis and allowing cells to exchange nutrients, ions, and waste products with their environment.
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.
What happens in the ring of fire?
Highly active geological processes and activities.
Amino acids absorbed through two processes of?
Amino acids are absorbed through two processes: active transport and facilitated diffusion. Active transport requires energy and is used for absorption of essential amino acids, while facilitated diffusion does not require energy and is used for absorption of non-essential amino acids. Both processes occur in the small intestine.
A passive process requires energy?
An active process if that is carried out on the expense of energy and the passive processes is that occurs spontaneously in nature. for example consider two solutions separated by a membrane, one side you have high concentration of glucose than other. While passive transport of glucose will take place across the concentration gradient, for active transport, that is transport against concentration gradient, require external source of energy. Passive processes are thermodynamically favourable. The active processes are thermodynamically unfavourable. Thus in biological system most of the active processes are coupled with deposphorylation of ATP. The energy releases by the breaking of phosphodiester bond is used to carry out the active processes.
What is the opposite of pasive?
If you mean the opposite of passive transport, like through a membrane, the opposite is active transport.

Are endocytosis and exocytosis passive or active processes?
Endocytosis and exocytosis are active processes.

Is T3 or T4 more active in the body's metabolic processes?
T3 is more active than T4 in the body's metabolic processes.
What are the active transport processes?

Transporters are used for the processes of active and?
Transporters are the process of active and chemical energy. This is in the body.
3 types of pasive transport?

The energy required for active transport processes is obtained from what?
From ATP
Which processes are active transport of substances in and out of the cell?
cell membrane
