LSU BIOLOGY 1201 ACTUAL EXAM
QUESTIONS WITH REVISED AND
UPDATED ANSWERS
Cellular respiration - Answer-A redox process in which energy is released as hydrogen,
and electrons are transferred to oxygen atoms

NAD+ - Answer-A coenzyme that functions as an electron carrier

Dehydrogenase - Answer-An enzyme that removes a pair of hydrogen atoms (2
electrons and 2 protons) from the substrate; the extra proton is released a H+ ion

Electron transport chain - Answer-Breaks the fall of the extraneous electrons discarded
by the conversion of NADH to oxygen

Oxidative phosphorylation - Answer-Produces 90% of the ATP creates by cellular
respiration

2 Pyruvate - Answer-What does glycolysis produce

Twice - Answer-How many times does the citric acid cycle run per one molecule of
glucose

Chemiosmosis - Answer-ATP synthesis powered by the flow of H+ back across the
membrane

Cytochromes - Answer-Electron carriers that accept electrons from the electron
transport chain

None - Answer-How much CO2 is releases in lactic acid fermentation

obligate anaerobes - Answer-Carry out fermentation

Photosynthesis - Answer-Process that converts sunlight and water into energy within
chloroplasts

Autotroph - Answer-Organisms that sustain themselves without eating anything

Heterotroph - Answer-Organisms that obtain organic molecules from other organisms

Mesophyll - Answer-Plant tissue found in the leaves which hold chloroplasts

, Stomata - Answer-Pores on leaves that allow photosynthesis reactants to enter plants

Thylakoids - Answer-Connected sacs in chloroplast that hold chlorophyll

Endergonic - Answer-Is photosynthesis endergonic or exergonic?

Light reactions and the Calvin cycle - Answer-What are the two stages of
photosynthesis?

Carbon fixation - Answer-incorporating CO2 into organic molecules

Light - Answer-Electromagnetic energy, also called electromagnetic reactions

Action spectrum - Answer-A profile of the relative effectiveness of different wavelengths
for performing photosynthesis

Chlorophyll a - Answer-Plant pigment that has a CH3 functional group

Chlorophyll b - Answer-Plant pigment that has a CHO functional group

Carotenoids - Answer-Red/yellow pigments that work as a back up for chlorophyll; turn
leaves orange/red during the fall

Photosystem - Answer-A reaction center complex surrounded by energy harvesting
complexes

Cyclic electron flow - Answer-Photoexcited electrons cycle back from Fd to the
cytochrome complex

Carbon fixation, and CO2 acceptor regeneration - Answer-What are the three phases of
the Calvin cycle


Passive transport - Answer-No energy required; used for small molecules

Active transport - Answer-Requires energy; used for larger molecules

Amphipathic - Answer-having both a hydrophilic region and a hydrophobic region

Hydrophobic reactions - Answer-Phospholipids tend to pack together tightly and form ...
because it is the least energy consuming formation

Peripheral proteins - Answer-Proteins that are bound to the surface of the membrane

Integral proteins - Answer-proteins that penetrate the hydrophobic interior of the lipid
bilayer
