E. coli Bacteria

E.coli Bacteria

E. coli bacteria are among the numerous bacteria that reside in the digestive tract of humans and animals. While most E. coli strains are harmless, others have gained the ability to produce poisonous substances which cause disease. Through genetic engineering, scientists are finding ways to use E. coli to aid in the treatment of human disease.

Cell Cycle

Cells grow and replicate through an ordered series of events called the cell cycle.

Green Tea Improves Health

Studies suggest that drinking green tea improves health due to a compound called epigallocatechin gallate (EGCg). This compound has cancer inhibiting and anti-inflammatory properties.

Citric Acid Cycle

The citric acid cycle is a stage in cellular respiration that helps to harvest the energy stored in carbohydrates, proteins, and fats. These molecules are broken down into smaller components to be used as fuel by cells.
