The study of energy flow in living systems is known as bioenergetics, a branch of biochemistry. Energy conversion and transfer are involved in this exciting area of biological study. It has uses for mitochondrial metabolism and diseases of it as well as structural biology. The goal of the peer-reviewed, open access Bioenergetics journal is to publish the most thorough and trustworthy source of information on new findings and advancements in all fields of study through the publication of original articles, review articles, case studies, short communications, etc. and to make this information freely accessible online to researchers all over the world without any restrictions or additional subscriptions and also brings together a variety of disciplines to provide a platform for authors to contribute to the Journal.

The term "cell membrane" can also refer to as plasma membrane or Bio membrane. The membrane, which is present in every cell, is what divides the cell's interior from its exterior. In bacterial and plant cells, a cell wall is observed to be externally linked to the plasma membrane. A semipermeable lipid layer makes up the plasma membrane. It is in charge of regulating the flow of materials into and out of the cell as well as the movement of various compounds. The Bio membrane comprises membrane proteins in addition to a lipid layer between the phospholipids that keeps fluidity at a variety of temperatures. Peripheral proteins that adhere to the cell membrane's edges and integral proteins that operate as membrane transporters are also included in this. It essentially functions as the enzymes that mould the cell. The transport of particles into and out of organelles and cells is controlled by the plasma membrane, which is selectively permeable to organic molecules and ions. Proteins, lipids, and carbohydrates make up the fluid mosaic that is the Bio membrane. The Bio membrane's intricate structure is displayed in the image of the membrane that was previously provided. It can only pass through carriers, Trans membrane channels, and pumps for ions and water-soluble compounds. Trans membrane proteins establish a trans membrane electrical potential, control the intracellular ion concentration, and provide the cell with nutrients.

A protein-implanted phospholipid bilayer makes up this membrane. The plasma membrane creates a durable barrier between the two aqueous compartments that are located on the outside and inside of a cell, respectively. The implanted proteins carry out specialised tasks such as selective molecular transport and cell-cell recognition. The cell is protected by the plasma membrane, which also maintains a constant environment inside the cell. It is in charge of carrying out certain tasks. It must be flexible in order for substances like white blood cells and red blood cells to be able to change shape and travel through blood capillaries. Additionally, it attaches the cytoskeleton to give a cell shape and helps cells connect with extracellular matrix and other cells to build tissues. It also keeps the cell potential intact. The plasma membrane is in charge of connecting with neighbouring cells, which may contain lipid or glycoprotein proteins. Along with assisting in the movement of molecules across the membrane, the membrane helps the proteins monitor and regulate the chemical environment of the cell.
