OU BIO STIMULATOR EXAM 2
QUESTIONS WITH CORRECT
ANSWERS.
What do Golgi bodies do? - Answer Receive vesicle from the ER, modify and package
macromolecules, and transport them
Chloroplasts have - Answer a double membrane, contain DNA, and divide energy
Chloroplasts - Answer Capture light energy via thylakoid membranes and use it to synthesize
glucose
What does the endosymbiont theory propose - Answer Both the mitochondria and
chloroplasts were once prokaryotes engulfed by another cell
Photosynthesis combines - Answer O2 and H2O
Photosynthesis prodcues - Answer Glucose and O2
What are the three stages of photosynthesis - Answer Absorbing light energy, synthesizing ATP
and NADPH, converting CO2 into organic molecules
The first two stages of photosynthesis are - Answer light dependent reactions
The third stage of photosynthesis are - Answer Light independent reactions
Chloroplasts contain - Answer Internal thylakoid membranes and the stroma
What are found in the thylakoid membrane - Answer The photo systems involved in energy
capturing
What is found in the stroma - Answer Enzymes for assembling organic molecules
, chlorophyll a is - Answer The only pigment that can convert light energy into chemical energy
Chlorophyll b is - Answer An accessory pigment
What happens in photosystem I - Answer Transfers electrons to NADP+, and reduces it to
NADPH
What happens in photosystem II - Answer It replaces electrons lost by photosytem I
Electrons lost from photosystem II are - Answer Replaced by electrons from oxidation of water,
which produces O2
ATP synthase is a - Answer Channel enzyme
What happens when protons flow to their gradient - Answer ADP is phosphorylated,
producing ATP
How do plants make additional ATP - Answer Through cyclic photo phosphorylation
PNS sensory neurons - Answer Carry impulses to the CNS
Motor neurons - Answer Carry impulses away from the CNS
The sodium potassium pump - Answer Moves Na+ outside the cell, and K+ into the cell
What happens when K+ leaks - Answer It moves positive charge outside the cell
What happens if there's influx of Na+ during action potential - Answer the adjacent region
depolarizes, producing its open action potential
Where does an action potential terminate - Answer At the end of the axon at the synapse
