Answer:
The correct answer is ATP.
Explanation:
When molecules or ions moves into higher concentration from lower concentration through a cell membrane with the help of enzymes and requires energy, this type of transport of molecules or substances called active transport. Active transport requires chemical energy to perform this transport and ATP is the form of chemical energy expended in this process. ATP is an abrevation of adenosine triphosphate.
ATP is the energy expended in active transport.
Active transport is the homeostatic process that requires energy to move particles across the plasma membrane.
Further Explanation
Transport in living organisms
- Plants and animals use various processes to transport materials from one point to another.
- There are classified as either passive transport or active transport.
Active transport
- It is a type of transport in living organisms that involves movement of substances against a concentration gradient through the plasma membrane.
- Active transport is the homeostatic process that requires chemical energy to move particles across the plasma membrane.
- The chemical energy used during active transport is in the form of ATP.
Passive transport
- It is a type of transport that does not involve the use of energy to aid movement of substances in living organisms.
- Passive transport involves free movement of substances and through special types of transporters or carriers.
- Types of passive transport includes; simple diffusion, facilitated diffusion, osmosis, and mass flow among others.
Types of passive transport
Facilitated diffusion
- Facilitated diffusion is a type of passive transport which involves the diffusion of solutes by use of transport proteins in the plasma membrane.
- Facilitated diffusion uses transport proteins to transport solutes down their concentration gradient.
Osmosis
- Osmosis is a special diffusion that involves the movement of water molecules from a region where they are highly concentrated to a region where they are lowly concentrated through a semipermeable membrane.
- It may also refer to the movement of water molecules from a region of low particle concentration to a region of a high particle concentration.
Diffusion
- Diffusion is a type of passive transport that involves movement of particles from a region of high concentration to a region of low concentration.
- Diffusion involves movement of molecules of substances other than water.
