Portage Biochemistry Module 1 Exam
Questions and Answers 100% Solved
Definition of biochemistry - ✔✔chemistry of life; how properties of
organisms relate to their molecules
What are the 3 things biochemists study? - ✔✔1. The relationship
between structure and function of biomolecules
2. Chemical reactions of organisms (metabolism)
3. Communication within and among organisms
What are bulk elements? - ✔✔Elements that are abundant in living
organisms
What are trace elements? - ✔✔Elements that are less abundant in
organisms but still crucial for life
Name the bulk elements (10) - ✔✔H, Na, K, Ca, C, N, O, P, S, Cl
Name the trace elements (13) - ✔✔Mg, V, Cr, Mn, Fe, Co, Ni, Cu, Zn,
Mo, W, Se, I
What's another word for a firefly? - ✔✔Lightning bug

Explain the chemical reaction of lightning bugs - ✔✔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.
How many naturally occurring elements exist? How many are found in
living organisms and what kind of elements? - ✔✔90 naturally occurring
elements, less than 30 elements are found in living organisms.
Most of these 30 elements are smaller non-metals.
Why are smaller elements favored for living organisms? - ✔✔They can
form stable, covalent bonds
How are strong bonds formed? - ✔✔Strong bonds form by significant
overlap of atoms, such as carbon and hydrogen, permitting them to share
electrons
Why is the strong bond good for living organisms? - ✔✔The bond that
forms requires significant energy to break it. This means the bonds can
withstand mechanical and thermal pressures through the growth of
hair/skin for protection.
Do larger elements form stable covalent bonds? - ✔✔No
