CHEM 210 - BIOCHEMISTRY - MODULE 1
QUESTIONS AND ANSWERS ALL
GRADED A+ LATEST EDITION
What \do \Biochemists \study? \- \ANS-1. \The \relationship \between \structure \and \function \of \biomolecules
2. \Chemical \reactions \of \organisms
3. \Communication \within \and \among \organisms
Smaller \elements \are \favored \because \they \can \form \stable \covalent \bonds. \T \or \F \- \ANS-True. \Strong \
bonds \form \by \significant \overlap \of \atoms, \such \as \carbon \and \hydrogen, \allowing \them \to \share \
electrons.
What \is \the \bond \angle \of \a \Linear \molecule? \- \ANS-180 \degrees
What \is \the \bond \angle \of \a \Trigonal \Planar? \- \ANS-120 \degrees
What \is \the \bond \angle \of \a \Trigonal \Pyramidal? \- \ANS-107.5 \degrees
what \is \the \bond \angle \of \Tetrahedral? \- \ANS-109.5 \degrees
What \is \carbon \referred \to \in \the \chemical \world? \- \ANS-The \superglue
What \does \organic \chemistry \study? \- \ANS-Focuses \on \the \chemical \and \physical \properties \of \carbon \
compounds
, What \does \inorganic \chemistry \study? \- \ANS-The \field \dealing \with \metals, \minerals, \and \other \non-
organic \compounds
How \many \bonds \can \a \Carbon \form? \- \ANS-4! \Due \to \having \4 \valence \electrons
What \is \a \long \chain \of \carbons \called? \- \ANS-Polymers
What \is \a \cyclic \compound? \- \ANS-Carbons \joined \together \in \a \closed \chain
What \are \carbon \compounds \called? \- \ANS-Alkanes
Condensed \structures \give \a \better \idea \of \a \molecules \structure, \compared \to \chemical \formula. \T \or \
F \- \ANS-T
Structural \formula \gives \an \even \better \idea \of \a \molecules \structure, \compared \to \chemical \formula \- \
ANS-T
Advantage \of \cyclic \carbon \compounds \- \ANS-They \are \more \restricted \in \their \movements \and \
orientation \- \advantageous \for \building \structures \and \maintaining \shape
Carbon \can \form \double \and \triple \bonds \with \other \carbon \atoms \or \atoms \of \other \elements. \T \or \
F \- \ANS-T
Line-bond \Drawing \- \ANS-Most \efficient \method \to \show \structure, \but \requires \the \most \
interpretation.
Functional \group \- \ANS-specific \arrangement \of \atoms; \they \define \the \chemistry \of \the \molecule \and \
control \the \properties \of \the \compound.
What \dictates \the \chemical \and \physical \properties \of \compounds, \including \biochemical \
compounds? \- \ANS-The \structure
