There are five major ingredients to life. These ingredients include water, nucleic acids, proteins, lipids, and carbohydrates.
Nucleic acids make up genetic information found in living things, there are two types of nucleic acid DNA and RNA.
Water is the “filter” of the cell. It helps transport materials and proteins in and out of the cell. Otherwise known as Maintaining Homeostasis.
Each lipid has a unique function. Phospholipids create the cell membrane, unsaturated and saturated fats store and release massive amounts of energy. In addition cholesterol and hormones help in cell communication.
Each protein has a unique function including communication, transport in cell membranes, break down food with enzymes, and structural support. Proteins are located all over an organism.
Carbohydrates release energy including simple sugars and complex sugars as well as providing structural support and communication between cells.
DNA and RNA are very important molecules for life. DNA contains the genetic code for a cell. The DNA carries all the information for an organism in order for it to to grow, reproduce and survive. RNA is used to translate the information found in the DNA and then later use that information to build proteins. It is necessary to have these molecules in every cell because it wouldn’t be able to function properly, grow or reproduce or even survive.
Nucleic acids and proteins are related even though as molecules they are not similar in structure. They are related through their way of protein production. There are twenty different kinds of amino acids that can be put together in many different ways. Amino acids are put together according to the instructions found in the DNA and RNA. There are hundreds of different kinds of proteins because amino acids can be put together in a vast amount if ways. It is necessary for cells to have these molecules in every cell because without DNA and RNA there would be no protein, without protein cells couldn’t gain energy and without energy a cell isn’t capable of doing anything in order to survive.
Phospholipids are extremely important to have in a cell. Phospholipids create your cell membrane (protective barrier) that prevents certain molecules from entering and exiting the cell. Phospholipids (Cell Membrane) make it possible for cells to have organelles and if cells didn’t have organelles there would be no life.
Protein and DNA provide a cell with enough energy to perform the characteristics of life as well as other functions like transport and repair. Proteins break down food with enzymes helping the process of turning food into energy. In addition, proteins also transport within cell membranes and repair. DNA contains the permanent code for heredity, growth and reproduction and reacting to stimuli. Together Protein and DNA provide energy and the way to function the six characteristics of life. Without Protein and DNA there would be no way for a cell to function correctly or survive.
