Cell transport, that is, the movement of molecules across the cell membrane, involves homeostasis (i.e. balance in the cell). Notice that the movement of molecules goes from a high concentration to a low concentration here, this is considered passive transport. Active transport would be going from low to high.
What would you call the process that is happening here?
energy is converted as well as new molecules are formed
new molecules are formed and ATP is produced
Active transport is required and homeostasis (balance) is achieved
Molecules are moved and homeostasis (balance) is achieved
Cell transport (i.e. the movement of molecules across the cell membrane) involves homeostasis (i.e. balance in the cell).
