Myosin is one of the proteins known to scientists as an ATP-dependant motor protein and is recognized as one of the most abundant proteins in the human body. Its structure and function allows myosin to perform a characteristic function in the eukaryotic cell, which is...
What is mitochondrial DNA (mtDNA)?
By: Jayson Precht
Mitochondria produce energy for your cells. They are believed to have originated from a symbiotic relationship between bacteria and cells a very long time ago. Eventually the bacteria became part of the cell, specifically the mitochondria. This explains why mitochondria have their own set...
DNA and its relationship to family history
By: P.D. Rivers
If you are a person interested in family genealogy you have probably used one of the popular family tree websites. Lately there has been a push with these sites, as well as with National Geographic, to gather DNA from families worldwide and compare them. To...

Use of plastic contributes to global warming, since it is fossil fuel based. It also has many contaminants that are proven to upset endocrine systems in humans and other animals. A book called “Death by Rubber Ducky” lists this and many other disadvantages of...
A short introduction to photosynthesis
By: Jose Juan Gutierrez
Photosynthesis is the process by which plants, algae and photosynthetic bacteria use the energy from the sun and convert it into chemical energy that is used by plants and other living organisms that depend on them. The process of photosynthesis absorbs carbon dioxide (CO2) from...

Plants use glucose in a variety of ways that are essential to their growth and survival. Glucose aids in overall growth, allows for respiration through the cell walls and is also stored for future use in the roots, as well as in the form of...

Photosynthesis is a complex process whereby plants, algae and some bacteria receive energy from the sun. The energy from sunlight is used to synthesize carbon dioxide and water into glucose and oxygen. Photosynthesis converts electromagnetic energy from sunlight into a chemical energy stored in glucose...

To be able to understand how the size of a molecule is related to its biological function, you must first know the concept of a lock and key. When the key does not match the lock, then you are unable to open the lock. This...
What are heterotrophs and autotrophs?
By: Jose Juan Gutierrez
Living organisms obtain their energy in varied ways. Some organisms, including animals, fungi and bacteria capture their energy by feeding on the organic substances produced by other living organisms; such organisms are known as heterotrophs. Other organisms obtain their energy from inorganic molecules. These organisms...

The fun thing about ionic bonds is that they really aren't anything like covalent bonds. There is no sharing of electrons, and there is no pairing up of atoms. There isn't even a single ionic bond that you can point to, since the bonding happens...
