BI234 METABOLISM QUIZ AND ANSWERS WITH
COMPLETE SOLUTIONS VERIFIED LATEST UPDATE
Where does photosynthesis happen in eukaryotes vs prokaryotes?
Eukaryotic: happens in chloroplasts (the pigment molecule is chlorophyll) (plants and
protozoans)
Prokaryotic: happens in the cell membrane (pigment molecule is the
bacteriochlorophyll) (bacteria)
Why do bacterial cells have folded membranes?
Because it increases the surface area and allows for more pigment molecules to be
present and therefor for the organism to make more ATP
Catabolism vs Anabolism
catabolism: break down of organic molecules (makes energy)
anabolism: synthesis of organic molecules (uses energy)
What biomolecule does photosynthesis use?
Carbohydrates (sugars)
What biomolecules can go through the fermentation process?
carbohydrates and proteins
What is the goal of fermentation?
to generate NAD+ to allow for more glycolysis reactions to occur
, Where does ATP come from in fermentation?
only glycolysis
Where does the process of cellular respiration happen in eukaryotic vs
prokaryotic cells?
Eukaryotic: glycolysis happens in the cytoplasm, the Krebs cycle happens in the
mitochondria and the electron transport chain is the inner mitochondria membrane
Prokaryotic: all happens in the cytoplasm and the electron transport chain is the cell
membrane
Where does the process of fermentation happen in eukaryotic vs prokaryotic
cells?
For both Eukaryotic and Prokaryotic organisms the fermentation process happens in the
cytoplasm
How does the electron transport chain gain energy to pump H ions out of the
cell?
It gains energy by ripping a Hydrogen off of NADH and FADH2
This new gradient of an abundance of H ions outside of the cell is what allows for H ions
to flow back into the cell through the ATP synthase enzyme
What is anaerobic respiration?
It is the exact same as aerobic cellular respiration except that there is a different
electron receptor at the electron transport chain rather than O2
What kind of pathways of fermentation and cellular respiration?
