It is found in skeletal muscles. Creatine phosphate can house high-energy phosphate bonds. There is an abundance of ATP while the muscle cell is at rest. The creatine kinase transfers the high-energy phosphate bonds of the ATP to the high-energy phosphate bonds of the creatine phosphate. Once the cell is ready to contract, creatine kinase removes the phosphate groups from creatine phosphate and transfers them to ADP to create ATP. ATP is used to drive the contraction since it is a quick energy source. A large amount of creatine kinase should not be present in the bloodstream unless there is a large-scale destruction of muscle cells. The Duchenne muscular dystrophy causes this phenomenon to occur where muscle cell membranes are destroyed spilling out the creatine kinase into the bloodstream.

Adenosine triphosphate (ATP) is a multifunctional nucleotide used in cells as a coenzyme. It is often called the "molecular unit of currency" of energy transfer. ATP transports chemical energy within cells for metabolism. It is produced by photo-phosphorylation and cellular respiration and used by enzymes and structural proteins in many cellular processes, including active transport, respiration, and cell division. One molecule of ATP contains three phosphate groups, and it is produced by ATP synthase from inorganic phosphate and adenosine diphosphate (ADP). ATP is used is many organisms and also in different ways. Below are a few ways in which ATP is used.

An individual that plays only part of its role because of competition or other types of species interactions is said to display a realized niche. Species over time divide the resources they commonly use by specializing in different ways.

In this preparative lab, an aldol (trans-p-anisalacetophenone) was produced from the reaction between p-anisaldehyde and acetophenone with the presence sodium hydroxide. The reaction also showed the importance of an enolate and the role it played in the mechanism. Sodium hydroxide acts as a catalyst in this experiment and is chosen because of its basic conditions and pH. The acetophenone carries an alpha hydrogen that has a pKa between 18 and 20. This alpha hydrogen is acidic because of its location near the carbonyl on acetophenone. When the sodium hydroxide is added, it deprotonates the hydrogen and creates an enolate ion. This deprotonation creates a nucleophilic carbon that can attack an electrophilic carbon (like a parent
