FSU Marks Final Exam BSC2010 questions with verified
answers
Ans✓✓✓
(1) The light reactions Ans✓✓✓ - occur on the thylakoid membranes of
the chloroplast or on membranes of certain prokaryotes
- convert solar energy to the chemical energy of ATP and NADPH
- releases oxygen
- splits water molecules
- reduces NADP+ to NADPH
- generates ATP using photophosphorylation
(2) The Calvin Cycle Ans✓✓✓ - occurs in the stroma
- forms sugar from CO2 using energy from ATP and NADPH
[H+][OH-] should add up to get... Ans✓✓✓ 10-14
Acid Ans✓✓✓ - increases H+ concentration
- pH goes down, <7
- donate H+ in aqueous solutions
Active proteins Ans✓✓✓ - ligand bound receptor
,- binds to G protein
- GTP
- kinase + phosphorylation
Amino acid monomers Ans✓✓✓ organic molecules with carboxyl and
amino groups. They differ in their properties due to differing side chains
called R groups
Amino Ans✓✓✓ - basic
- [H+] does down
- 1 N, 3 H's
Atomic mass Ans✓✓✓ the number of protons and neutrons
Atomic number Ans✓✓✓ the number of protons in the nucleus of an
atom
Base Ans✓✓✓ - decreases H+ concentration
- pH goes up, >7
- donate OH- or accept H+ in aqueous solutions
, Be able to follow electrons as they are passed from glucose molecules
eventually to oxygen Ans✓✓✓ Glucose -> NADH and FADH2 ->
Electron Transport Chain -> Proton Motive Force -> O2
Be able to follow potential energy as it is passed from a glucose
molecule to ATP molecules Ans✓✓✓ Glucose -> NADH + FADH2 ->
Electron Transport Chain -> Proton Motive Force -> ATP
Carbonyl Ans✓✓✓ - polar
-C=O
Carboxyl Ans✓✓✓ - acidic
- [H+] goes up
- 1 C, 2 O's
Chemical equilibrium Ans✓✓✓ is reached when the forward and
reverse reaction rates are equal. At equilibrium, the relative
concentrations of reactants and products do not change
Chemiosmosis Ans✓✓✓ A process for synthesizing ATP using the
energy of an electrochemical gradient and the ATP synthase enzyme
Chromatin is made of both DNA and histone proteins. What do histone
proteins do? Ans✓✓✓ Package and unpackage the DNA
