Special proteins -- known as membrane transporters -- are key to the mobility of sperm cells. A research team has, with the aid of cryo-electron microscopy, succeeded in decoding the structure of ...

Mitochondria are cell organelles surrounded by a double membrane. In addition to numerous essential functions in the ...

Cell Energy and Cell Functions Cells manage a wide range of functions in their tiny package — growing, moving, housekeeping, and so on — and most of those functions require energy.

A plasma membrane is permeable to specific molecules that a cell needs. Transport proteins in the cell membrane allow for selective passage of specific molecules from the external environment.

Researchers from the National University of Singapore (NUS) have solved a 60-year-old mystery in bacterial cell envelope ...

Study: Impact of Escherichia coli Outer Membrane Vesicles on Sperm Function. Image Credit: SciePro / Shutterstock.com Introduction Most MRTIs are caused by bacteria including Staphylococcus ...

Functions: Plasma membrane permits the entry and exit of some materials in the cells. Therefore, plasma membrane is known as selective permeable membrane. (i) Diffusion: The spontaneous movement ...

Researchers from Osaka University have identified a new sperm membrane protein that facilitates the complex sperm-oocyte fusion that is fundamental to sexual reproduction, naming it Fertilization ...

Many proteins with important biological functions are embedded in a biomembrane in the cells of humans and other living organisms. But how do they get in there in the first place? Researchers in the ...

A ribosome is a complex macromolecular structure in the cell which is involved in the process of translation. This is an essential function of all living cells, allowing for the production of ...

How sperm find their way Date: November 15, 2018 Source: University of Tokyo Summary: Researchers have found that a protein in the cell membranes of sperm plays a key role in how they find their ...

Unlike other organelles (miniature organs within the cell), mitochondria have two membranes, an outer one and an inner one. Each membrane has different functions.
