What are three ways that biochemists study biological organisms? - correct answer -1. The
relationship between structure and function of biomolecules.
2. The chemical reactions of organisms and or metabolism.
3. Communication with and among organisms.
What is the definition of biochemistry? - correct answer -Biochemistry is referred to as the
'chemistry of life' as it investigates how the properties of organisms relate to their molecules.
What elements are important to human life? - correct answer -Bulk elements and trace
elements.
Bulk elements consists of non-metals and trace elements consist of transition metals and
metals.
Trace elements are important in small amounts.
What are considered bulk elements? - correct answer -C, H, N, O, P, S, Cl, Na, K, Ca.
What are considered trace elements? - correct answer -Mg, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Mo, W,
Se, I.
, What is another name for firefly? - correct answer -Lightning bug or glow worm. Fireflies are
also known to be beetles.
What are the different bond shapes? - correct answer -Linear, Trigonal planar, Trigonal
pyramidal, Tetrahedral, Bent.
Linear - correct answer -180 degrees, sp hybridization.
A straight-line arrangement of atoms.
Trigonal Planar - correct answer -120 degrees, sp2 hybridization.
A central atom with three bonded groups in a flat, planar structure.
Trigonal Pyramidal - correct answer -107.5 degrees, sp3 hybridization.
A trigonal pyramidal shape occurs when a central atom forms three bonds and has one lone pair
of electrons.
Tetrahedral - correct answer -109.5 degrees, sp3 hybridization.
A central atom with four single bonds, forming a 3D tetrahedron.
Bent - correct answer -104.5 degrees, sp3 hybridization. 120 degrees, sp2 hybridization.
