Question

Difference between passive transport and active transport

Answer 1

Hint: The transport is the act by which molecules, ions, or substrates are moved across a biological membrane, such as the plasma membrane, etc. It may also pertain to or refer to the moving of electrons in an electron transport chain.

Complete answer:
- The very first thing is that the molecules are moved within and across the cell membrane and thus transporting it through the concentration gradient, without using ATP (energy).
-Cellular energy is not needed for passive transport.
- In this process, the circulation takes place opposite to the active transport, that is from a region of higher concentration to a region of lower concentration.
-It is a physical process and also a comparatively slow process.
- The main aim is to transport all soluble molecules, including oxygen, water, carbon dioxide, lipids and mainly sex hormones.
-In passive transport, the carrier proteins are not at all required.
-Transportation is bidirectional.
-Passive transport is partly non-selective.
- Metabolic inhibitors cannot influence passive transport.
-It is not influenced by temperature.

Additional Information:
- In Active transport the molecules are moved across the cell membrane and also the action is pumping the molecules against the concentration gradient using ATP (energy).
-Active transport requires cellular energy.
-In this process, the circulation takes place from a region of lower concentration to a region of higher concentration.
-It is a dynamic and rapid process.
-In this transport, the main aim is to transport all molecules, for example, proteins, large cells, complex sugars, ions, etc.
-The active transport, carrier proteins are required.
-Transportation is only in one direction.
-Active transport is highly selective.
-Active transportation is influenced by metabolic inhibitors.
- It is influenced by temperature.

Note:
Active transport requires energy for the movement of molecules but passive transport does not require energy for the movement of molecules. Inactive transport, the molecules move against the concentration gradient but in passive transport, the molecules move along the concentration gradient. And also to and fro transport of materials is controlled by the permeable cell membrane
