Metabolism & Enzyme Regulation

Metabolism is the combined sum of the chemical reactions that occur in living organisms. Metabolism is traditionally divided into catabolism, or the breaking down of large molecules into smaller ones, and anabolism, or the combining of small molecules to make larger ones. Metabolic pathways are coordinated series of reactions, catalyzed by enzymes and designed to…

Energy Flow in Living Systems

Living organisms must continually capture/acquire, store, and use energy to carry out the functions of life. Capturing/acquiring, storing and using energy are accomplished through cellular chemical processes. Cells are chemical machines that obey fundamental chemical and physical laws of nature. The sum of a cells chemical reactions is called metabolism. Energy Energy is the ability…
