CELLS
1. What is a cell? Cellular physiology is the study of the functions and behavior of cells, their genetic information, and their interaction with their surroundings. Cellular physiology is essential for understanding the mechanisms underlying normal and abnormal cellular functions, as well as for investigating the causes of disease. Cellular physiology is divided into two main branches: cellular biochemistry and cellular physiology. Cellular biochemistry focuses on the chemical processes that occur within cells, while cellular physiology focuses on the cellular functions and behavior that result from these processes. Cellular biochemistry is subdivided into four major subfields: protein synthesis, carbohydrate metabolism, lipid metabolism, and nucleic acid metabolism. Protein synthesis is responsible for the production of the proteins that make up the cell's structure and function. Carbohydrate metabolism involves the metabolism of glucose, fructose, and other sugars. Lipid metabol...
