A recent study by Chinese scientists has revealed the intricate molecular machinery driving energy exchange within ...

This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule. DNA and RNA are composed of nucleotides that are linked to one another in a chain ...

Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike ...

ATP works by losing the endmost phosphate group when instructed to do so by an enzyme. This reaction releases a lot of energy, which the organism can then use to build proteins, contact muscles, etc.

A sugar molecule, a base, and a phosphate molecule group together to make up a nucleotide. Nucleotides are abundant in the cell's nucleus. Nucleotides are the units which, when linked sugar to ...
