11 receptor proteins specific to hormones- the primary requirement of cells for giving response to a hormone is receptor for recognition for cells.
Other options are secondary for response
12 Active ion transport - Active ion transport involved in transporting ions against the concentration gradient so it makes imbalance in the intracellular and extracellular concentration. So there is difference in ion concentration.
Passive diffusion maintains balance so there will not be difference in ion concentration.

12. In a cell, the difference in ion concentration between the intracellular and extracellular fluids results from a. active ion transport. b. passive diffusion of ions. c. bulk movements of intracellular and extracellular fluids. d. both active ion transport and passive diffusion of ions.

Diffusion Is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across a space. Facilitated transport Facilitated diffusion is the process of spontaneous passive transport of molecules or ions across a biological membrane via specific transmembrane integral proteins. Channels The integral proteins involved in facilitated transport are collectively referred to as transport proteins, and they...

How does facilitated diffusion differ from simple diffusion? Facilitated diffusion requires ATP Facilitated diffusion requires a solute-specific protein carrier Facilitated diffusion transports solute against its’ concentration gradient Which of the following is TRUE about primary active cell membrane transport? It is a form of transport that requires a protein “pump” It is a form of transport that transports ions and/or solute against their concentration gradient It is a transport mechanism that requires energy released from the splitting of ATP by...
