Metabolism Essay Topics

Metabolism: Cellular Respiration and New World Encyclopedia

Enzymes are molecules that are responsible for chemical reactions that occur within the body. They act as catalyst by accelerating metabolic reactions from the digestion of foods to synthesizing deoxyribonucleic acid (DNA). An enzymatic reaction changes substrates, the beginning molecule, into products. Enzymes are selective for the type of substrate that they will bind to;… View Article

Biochemical Basis of HFI

1. 2 Important Features of Enzymes Enzymes are proteins used in chemical reactions. In the reactions, enzymes act as catalysts. They function to speed up chemical reactions without using the enzymes themselves. The catalysts are neither the reactor nor the product. The first feature discussed in the text is the energy of the reaction. Catalysts… View Article

The Effect of Temperature on the Rate of Yeast Respiration

Abstract Carbon dioxide is a waste product of yeast respiration. A series of experiment was conducted to answer the question; does temperature have an effect on yeast respiration? If the amount of carbon dioxide is directly related to temperature, then varying degrees of temperature will result in different rates of respiration in yeast. The experiment… View Article

The concept of homeostasis

Homeostasis is the maintenance of a constant internal environment in organisms. It involves volume of blood and tissue fluid within restricted limits, it also maintains chemical makeup of the blood. Autonomic control systems throughout the body maintain temperature and water levels, which are required for cells to function properly. Although homeostasis maintains the internal environment… View Article

Role of energy in the body
