Chapter 2 The Identifying nutrients Gizmo Gizmo Quiz – A living cell is composed of a small number of Chemistry of Life elements, mainly carbon, hydrogen, nitrogen, Milk Lab oxygen, phosphorous and sulfur. Carbon, because of its small size and four available bonding electrons, can join to other carbon atoms in chains and rings to form large and complex molecules. The essential functions of cells involve chemical reactions that involve water and carbohydrates, proteins, lipids and nucleic acids. A special group of proteins, Gelatin Lab enzymes, enables chemical reactions to occur within living systems. Liver Lab Cell functions are regulated. Complex interactions among the different kinds of molecules in the cell cause distinct cycles of activities, such as growth and division. Most Chapter 2 Test cells function within a narrow range of temperature and pH. At very low temperatures, reaction rates are slow. High temperatures and/or extremes of pH can irreversibly change the structure of most protein molecules. Even small changes in pH can alter how molecules interact.
