Metabolism and Valence Electron Energy
By: Art Ayers
ATP is produced in cellular metabolism by using the high energy of valence electrons around carbon and hydrogen. more...
A Simple Explanation of Adenosine Triphosphate
By: Bridget Coila
All cells need energy to function. Adenosine triphosphate, created using food or sunlight, is the molecule that cells use to store that energy for future use. more...
By: Diane Ursu
Atoms are the basic building blocks of matter. They form the molecules that are involved in the processes of living systems. more...
Cell Metabolism is a Defining Feature of Life
By: Deborah Percy
What is cell metabolism? Obtaining food and converting it to energy is one of the features of life. This happens within animals, plants and individual cells. more...
By: Art Ayers
Water is highly organized by contact with the double layer of membrane lipids. Hydrophilic phosphates of the phospholipids hydrogen bond into the water surface layers. more...
By: Art Ayers
Water at the surface is frozen in a stretched sheet of optimally bonded molecules, as molecules shake into the minimal energy configuration. more...
Hydrophobic, Hydrophilic and Hydrogen Bonds
By: Art Ayers
Molecules that form hydrogen bonds with water are hydrophilic and those that can't are hydrophobic. more...
Hydrogen Bonds Form Biological Structures
By: Art Ayers
Cell membranes, ribosomes, protein complexes and biological macromoles such as nucleic acids and proteins are held together by hydrogen bonds. more...
Cell Metabolism and Energy Basics for Everyone
By: Donald Reinhardt
Energy abounds in organic molecules and the key, as in mining ore, is to extract and process it. Simple bacterial cells and highly complex organisms do this well. more...
Reaction Specificity of Enzymes
By: Art Ayers
Enzymes bind to particular molecules, because the protein secondary structure rigidly displays amino acid functional groups that make multiple bonds with the molecules. more...
By: Kenneth Rosen
Proteins are a major component of all of our cells. Amino acids are the building blocks of protein. Amino acids can be grouped according to their chemical behavior. more...
Angiotensin II Signaling Pathways
Tyrosine kinase signaling is but one path activated by angiotensin II to regulate fluid balance, cell growth, and more. more...
Oxygen and Dietary Antioxidants
By: Tamara Golden
Why do we breathe oxygen? Oxygen is necessary for life, and the human brain can only survive a few minutes without oxygen. So why the great interest in antioxidants? more...
LSD – Psychedelic Hallucinogen
By: Simon Davies
The history of a drug with remarkable potential which was banned through misuse by "hippies." more...
