Does Cell Membrane Produce Energy: 7 Facts You Should Know

In this article we article we are focusing on the cell membrane whether it produces energy or not and the topic is “Does Cell Membrane Produce Energy: 7 Facts You Should Know”.

A cell membrane is sometimes called as the plasma membrane is present in all the cells of plants and animals. It creates a separation between the outside and the inside environment of the cell. Cell membrane exists as a semipermeable bilayer of the lipid.

The cell membrane regulates the entry of the nutrients and exit of the toxic materials across the cell membrane. cell membrane protects the cell from the toxic external environment and the microbial attack.

Functions of the Cell Membrane

  • Cell membrane is semipermeable barrier or we can say permeable to only selective materials.
  • Plasma membrane or cell membrane functions in transporting solutes in and out of the cells using two transport mechanisms Active and Passive transport.
  • Cell membrane plays a role in transportation of large molecules as well which are called macromolecules using different process.
  • Cell membrane also plays a significant role in signal transduction process which occurs through the receptors when the receptor comes in contact with a ligand.
  • The cell membrane helps in cell-to-cell interactions for the exchange of the materials and the other information.
  • Cell membrane is involved in energy conversion from one type to the other for instance, during photosynthesis light energy from the sun is converted to the chemical energy in plants.

What is a Cell membrane?

Cell membrane is also known as plasma membrane which is present in all the cells and provides a protective coating to the cells from the toxic external chemicals and microbial invasion.

Plasma membrane provides a separation between the internal and external environment of the cell. It is a semipermeable membrane made up of a bilayer of crosslinking network of lipids. It also regulates the transport of the substances in and out of the cell across the membrane.

What produces the energy in a cell?

Cell contains organelle which performs different kind of functions to keep the cell active and alive, one of the organelles which contains a significant role in producing energy is known as Mitochondria. Mitochondria is also known as the energy generator or the power house of the cell.

Mitochondria is responsible for the generation of almost all the chemical energy inside the cell which is produced as a result of the biochemical reactions occurring inside the cell. It produces energy in the form of ATP molecules (Adenosine triphosphate) and also, they have their own genomic DNA and undergo multiplication individually.

What is the role of cell membrane in energy production?

Mitochondria contains double layered membrane which perform their own functions inside the cells. It consists of two membrane compartments, the outer membrane, an inner membrane and a small space between the two called intermembrane space.

The outer membrane is more permeable and contains large pores while the inner membrane is less permeable and consists of small pores. The inner membrane contains proteins that are involved in ATP production and electron transport chain.

How does cell membrane produce energy?

The inner membrane of the mitochondria contains certain protein complexes that are involved in catalyzing electron transport chain. Oxidative phosphorylation involves the transfer of electrons from NADH and FADH2 through the protein complexes present in the inner membrane.

A gradient of hydrogen ions is created in the membrane of mitochondria as the electrons pass through the complexes of the protein present in inner membrane. Cells absorb the energy generated by this proton gradient to produce more ATP molecules.

Why does cell membrane produce energy?

The mitochondrial inner membrane is involved in energy synthesis in the form of ATP. Energy is greatly needed for a cell to function and to undergo different processes occurring inside the cell such as, replication, transcription, translation, transport process, muscle contraction and various signaling process.

Which cell membranes produce energy?

The inner membrane of the mitochondria is involved in the ATP production. It is semipermeable and contains small pores. Inner membrane consists of the protein complexes that participate in electron transport chain and oxidative phosphorylation.


To conclude the article, we can say that cell membrane of the mitochondria is involved in energy production in the form of ATP that is utilized by the cell for various purposes.
