Aerobic Cellular Respiration
What is the role of oxygen in typical aerobic cellular respiration?
Oxygen is the final electron acceptor
Where does Kreb's cycle take place?
Mitochondrial matrix
What is photosynthesis?
The process of which light is converted to chemical energy in form of sugars
Which organelle carries out the reactions?
Chloroplast
Is fermentation considered a form of anaerobic respiration?
Yes
What is the overall equation (in words) for aerobic cellular respiration?
Glucose + oxygen - carbon dioxide + water
What product is created when oxygen acts as the final electron acceptor?
Water
What is the overall equation (in words) for photosynthesis?
carbon dioxide + water - glucose + oxygen
What is the role of glucose?
Key product (the whole point of photosynthesis)
What two types of fermentation are anaerobic?
Lactic acid and alcohol
How many FADH2 electron carriers enter the electron transport chain per glucose molecule?
2
How many NADH are created during glycolysis?
2
What is the difference between autotrophs and heterotrophs?
Autotrophs can make their own food while heterotrophs cannot
Is photosynthesis found in autotrophs, heterotrophs, both?
autotrophs
Which stage of cellular respiration is present in anaerobic respiration?
Glycolysis
How much net ATP is produced in glycolysis?
4 ATP invested, 2 ATP created = net gain of 2ATP
How is NAD+ different from NADH?
NAD+ is not carrying electrons. NADH is carrying electrons.
It is a waste product formed when water drops off electrons
What is the electron carrier of photosynthesis?
NADPH
What type of organism carries out alcoholic fermentation?
Yeast, some bacteria
How do you know that ATP synthase is an enzyme?
It ends in “ase”
What molecule enters the Krebs cycle?
Pyruvate
How many different types of photosynthesis are there?
What is the role of CO2 in photosynthesis?
Adds carbon to Calvin Cycle so that glucose can be made
Why is it so important to regenerate NAD+ during fermentation?
So that glycolysis can continue to happen and generate some ATP
