Definition of biochemistry - 🧠 ANSWER ✔✔chemistry of life; how properties
of organisms relate to their molecules
What are the 3 things biochemists study? - 🧠 ANSWER ✔✔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? - 🧠 ANSWER ✔✔Elements that are abundant in
living organisms
What are trace elements? - 🧠 ANSWER ✔✔Elements that are less
abundant in organisms but still crucial for life
Name the bulk elements (10) - 🧠 ANSWER ✔✔H, Na, K, Ca, C, N, O, P, S,
Cl
Name the trace elements (13) - 🧠 ANSWER ✔✔Mg, V, Cr, Mn, Fe, Co, Ni,
Cu, Zn, Mo, W, Se, I
What's another word for a firefly? - 🧠 ANSWER ✔✔Lightning bug
Explain the chemical reaction of lightning bugs - 🧠 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.
How many naturally occurring elements exist? How many are found in
living organisms and what kind of elements? - 🧠 ANSWER ✔✔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? - 🧠 ANSWER
✔✔They can form stable, covalent bonds
How are strong bonds formed? - 🧠 ANSWER ✔✔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? - 🧠 ANSWER ✔✔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? - 🧠 ANSWER ✔✔No
Describe the role of Iron as a larger element - 🧠 ANSWER ✔✔Iron has a
critical role in hemoglobin for oxygen transport in vertebrates.
Forms an ion capable of binding to oxygen.
Describe H and O in H2O - 🧠 ANSWER ✔✔Both H and O are found in large
amounts. They are small atoms that form strong bonds. When bonded as
