“Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules”. Proteins are “Macromolecules that contain nitrogen as well as carbon‚ hydrogen‚ and oxygen”(Miller‚ Kenneth R.‚ and Joseph S. Levine 48). Macromolecules are exceedingly large molecules that can be made up of several lesser molecules called proteins. These proteins are made up of numerous amino acids‚ which are “Compounds with an amino group (-NH2) on one end

Photosynthesis Experiment Introduction Photosynthesis is a process used by plants‚ making inorganic molecules into organic molecules (food) using sunlight. Carbon dioxide + Water (mainly from rain) Glucose + Oxygen From this process‚ carbon dioxide comes from environment. Glucose‚ as a product is used to make energy for growth. Lastly‚ the oxygen is a waste product in this chemical reaction‚ which become part of the Earth’s atmosphere. At this experiment‚ carbon dioxide and water

Importance of Organic Foods The definition of organic agriculture is farming with the use of synthetic chemicals. After World War II‚ larger and increasingly automated farms‚ known as "factory farms‚" put the synthetic fertilizers‚ pesticides and herbicides developed in the 1920s into widespread use. They found that more crops could be produced mass produced. What they did not realize were the dangers of using these chemicals and the effects they would have on the environment and human health

EXPERIMENT 7: PERCENTAGE OF OXYGEN IN KClO3 Introduction: In this experiment you will determine the percentage of oxygen in potassium chlorate. You will calculate the theoretical value from the chemical formula and compare your experimental value to the theoretical value. Background: When potassium chlorate (KClO3) is heated‚ it undergoes chemical decomposition. Oxygen gas (O2) is given off and potassium chloride (KCl) remains as the residue. The equation for the decomposition of potassium

Molecule Assignment Parmvir Deo The molecule that I chose was creatine Creatine’s organic role cannot be disparaged. It assumes a key biological role for mammals‚ fish‚ reptiles and amphibians. Creatine helps muscles in delivering adenosine triphosphate (ATP)‚ the substance that facilitates blasts of energy down to the cellular level. Creatine is put away in muscle cells as phosphocreatine and is utilized to produce cell vitality for muscle compressions. The phosphate of ATP is exchanged to creatine
