Introduction to Biochemistry: Principles, Biomolecules, and Cell
Structure Exam #1 Questions with Correct Answers
What is biochemistry? - ✔✔The branch of science that studies the chemical
substances and processes occurring in living organisms.
What are the two main types of biochemical substances? - ✔✔Bioinorganic
substances (e.g., water, inorganic salts) and bioorganic substances (e.g., proteins,
carbohydrates, lipids, nucleic acids).
What percentage of the human body is composed of water? - ✔✔70%.
What is the role of biochemistry in understanding human body functions? - ✔✔It
explains how nutrients are utilized, how energy is produced, and how organs
function normally.
What is the significance of biochemistry in disease diagnosis? - ✔✔Many diseases
cause changes in biochemical substances in the body, which can be detected
through laboratory tests.
What are some examples of biochemical tests performed by medical
technologists? - ✔✔Blood glucose tests, cholesterol tests, liver function tests, and
kidney function tests.
How does biochemistry contribute to monitoring treatment? - ✔✔It helps
determine if treatments are effective, such as monitoring blood sugar levels in
diabetic patients.
, What are the principal areas of biochemistry? - ✔✔Structural chemistry,
metabolism, and molecular genetics.
What does structural chemistry study? - ✔✔The relationship of the molecular
structure of biochemical substances to their biological functions.
What is metabolism in biochemistry? - ✔✔The totality of chemical reactions that
occur in living organisms.
What does molecular genetics aim to understand? - ✔✔The chemistry of the
processes and substances that store and transmit biological information, including
heredity and genetic expression.
What are the functions of proteins in biochemistry? - ✔✔They build and repair
tissues and function as enzymes and antibodies.
What is the main source of energy among carbohydrates? - ✔✔Examples include
glucose, starch, and glycogen.
What is the role of lipids in the body? - ✔✔They provide long-term energy
storage, are important components of cell membranes, and contribute to the
palatability of food.
What is the relationship between physiological and pathological chemistry? -
✔✔Physiological chemistry deals with processes under normal conditions, while
pathological chemistry deals with those under abnormal conditions.
