Biochemistry Basics
Biochemistry, the study of the chemical processes that occur within living organisms, provides a fundamental understanding of the molecular basis of life. It encompasses the structure, function, and interactions of biomolecules, including carbohydrates, lipids, proteins, and nucleic acids, which are essential for cellular function and metabolism.
Structure and Function of Biomolecules
Biomolecules are organic compounds that perform specific functions within cells. Carbohydrates, composed of sugars, provide energy and structural support. Lipids, including fats and oils, serve as energy reserves and form cell membranes. Proteins, made up of amino acids, are involved in a wide range of cellular processes, including catalysis, transport, and structural support.
Nucleic acids, such as DNA and RNA, store and transmit genetic information.
Enzyme Catalysis
Enzymes are proteins that act as catalysts, facilitating biochemical reactions without being consumed. They increase the rate of reactions by lowering the activation energy required for a reaction to occur. Enzymes are highly specific, each catalyzing a particular reaction or group of related reactions.
Their importance lies in enabling essential biochemical reactions to proceed efficiently within cells.

Key Concepts in Biochemistry
Biochemistry is the study of the chemical processes that occur within living organisms. It is a vast and complex field that encompasses a wide range of topics, from the structure and function of proteins to the regulation of metabolism. In this section, we will provide a brief overview of some of the key concepts in biochemistry.
pH and Biological Systems, Biochemistry basics pogil answer key
pH is a measure of the acidity or alkalinity of a solution. It is defined as the negative logarithm of the hydrogen ion concentration ([H+]). The pH scale ranges from 0 to 14, with 0 being the most acidic and 14 being the most alkaline (also known as basic).
The pH of pure water is 7, which is considered neutral.
pH is a critical factor in many biological systems. For example, the pH of the blood is tightly regulated between 7.35 and 7.45. Small changes in blood pH can have a significant impact on the function of enzymes and other proteins.
Glycolysis, the Citric Acid Cycle, and Oxidative Phosphorylation
Glycolysis, the citric acid cycle, and oxidative phosphorylation are three key metabolic pathways that generate energy for cells. Glycolysis is the breakdown of glucose, a sugar molecule, into two molecules of pyruvate. The citric acid cycle is a series of chemical reactions that occur in the mitochondria of cells and result in the production of carbon dioxide and ATP.
Oxidative phosphorylation is a process that occurs in the mitochondria and uses the energy from the citric acid cycle to generate ATP.
These three pathways are essential for the survival of cells. They provide the energy that cells need to carry out their functions, such as muscle contraction, protein synthesis, and cell division.
ATP as an Energy Currency
ATP (adenosine triphosphate) is a molecule that serves as the energy currency of cells. ATP is a high-energy molecule that can be broken down to release energy when needed. Cells use ATP to power a wide range of cellular processes, such as muscle contraction, protein synthesis, and cell division.
The ATP cycle is a continuous process that involves the breakdown and synthesis of ATP. Cells use ATP to store and release energy as needed.
