The cell is responsible for all the activities that occur inside our bodies. It is known as the basic unit of life. Important tasks are performed by specialized cells, which is required for the growth and development of the body. An essential transport system is used to transport the chemicals, nutrients, and other substances to other cells of the body. This transport mechanism is of two types, like active and passive transport. In this article, we will see the Difference Between Active and Passive Transport.
Active transport uses energy for the mobility of the molecules in and out of the cellular membranes and therefore remains active, whereas in passive transport the molecules do not use any energy for their movements and so they are known as passive. The main aim of these transport systems is to carry essential molecules and ions across the cellular membrane.
The outer layer is made up of the phospholipid bilayer. It maintains the homeostasis of the cell and checks the entry of the substances. The entry of the molecules is supported by the specialized proteins along with the semi-permeable membrane.
Difference Between Active And Passive Transport
Difference Between Active And Passive Transport
Character Active Transport Passive Transport
Definition In Active transport the molecules are moved across the cell membrane, pumping the molecules against the concentration gradient using ATP (energy). In Passive transport, the molecules are moved within and across the cell membrane and thus transporting it through the concentration gradient, without using ATP (energy).
Energy Active transport requires cellular energy. Passive transport does not require any cellular energy.
Circulation The circulation in this process is from a region of lower concentration to a region of higher concentration. The circulation in this process is from a region of higher concentration to a region of lower concentration.
Process It is a dynamic and rapid process. It is a physical and comparatively slow process.
Aim The main aim is to transport all molecules such as proteins, large cells, complex sugars, ions, etc. The main aim is to transport all soluble molecules, including oxygen, water, carbon dioxide, lipids, sex hormones, etc.
Protein The active transport, carrier proteins are required. The passive transport, carrier proteins are not required.
Direction Transportation is only in one direction. Transportation is bidirectional.
Selective Active transport is highly selective. Passive transport is partly non-selective.
Temperature It is influenced by temperature. It is not influenced by temperature.
Metabolic inhibitors Active transportation is influenced by metabolic inhibitors. Passive transportation is not influenced by metabolic inhibitors.
Types Exocytosis, Endocytosis, sodium-potassium pump. Osmosis, diffusion, and facilitated diffusion.
