Find practice Biochemistry Practice Questions with answers in Biology Tests exams here. Each question offers a chance to enhance your knowledge regarding Biochemistry.

Biochemistry is a subfield of science that focuses on the study of chemical processes and substances existing in living organisms. It deals with the research about biomolecule structure, function, and their interaction, including proteins, nucleic acids, carbohydrates, and lipids. All these molecules are capable of performing many biological processes, and three of them include cellular respiration, gene expression, and enzyme catalysis.

With a basis in molecular medicine, the most crucial sub-branch of this field is medical biochemistry, which consists of biochemical pathways and mechanisms lying beneath physiological function and pathological conditions. The prime importance of medical biochemistry is in the treatment process during the diagnosis of diseases and understanding progressions. Effective treatment always comes from medical biochemistry. For example, in more precise medical interferences if the possibility to identify biomarkers is available for diabetes and cardiovascular diseases.

The other area is nutrition and biochemistry. Nutrition is uptake and metabolism of nutrients, which may potentially make one healthy or prevent disease. Biochemistry explains how the body processes and uses the type of nutrition that comes in the forms of vitamins, minerals, carbohydrates, proteins, and fats. This information is relevant for diet guidelines and therapeutic diets in treating disorders like malnutrition and metabolic disorder.
