TOPIC 1: INTRODUCTION TO BIOCHEMISTRY
9 Questions • 10.2% of Exam • Fundamental concepts and definitions in biochemistry.
QUESTION 1
Definition of biochemistry
Correct Answer: Chemistry of life; how properties of organisms relate to their molecules.
QUESTION 2
What are the 3 things biochemists study?
Correct Answer: 1. The relationship between structure and function of biomolecules
2. Chemical reactions of organisms (metabolism)
3. Communication within and among organisms.
QUESTION 3
Explain the chemical reaction of lightning bugs
Correct Answer: The chemical reaction is called bioluminescence. Proteins regulate, produce, and degrade
the light-emitting compound called luciferin. Luciferin, when acted upon by a protein, glows as bugs move.
This chemical reaction is regulated by the protein (enzyme) called luciferase.
QUESTION 4
How many naturally occurring elements exist? How many are found in living organisms
and what kind of elements?
Correct Answer: 90 Naturally occurring elements, less than 30 elements are found in living organisms.
Most of these 30 elements are smaller non-metals.
QUESTION 5
Describe the role of Iron as a larger element
Correct Answer: Iron has a critical role in hemoglobin for oxygen transport in vertebrates.
Forms an ion capable of binding to oxygen.
