Cellular Respiration 1
What 2 things does Photosynthesis generate that is fuel for Cellular Respiration?
O2 (oxygen), and glucose
is a partial degradation of sugars that occurs without O2
fermentation
consumes organic molecules and O2 and yields ATP
aerobic respiration
What is the formula for Cellular Respiration?
C6H12O6 + 6 O2 --->6 CO2 + 6 H2O + energy
How many stages does harvesting energy from glucose have?
3
Where does NADH pass electrons?
electron transport chain
Does NAD+ accept or donate electrons?
accepts electrons
During cellular respiration, what is reduced or is the final electron acceptor for the ETC?
O2
During cellular respiration, what is oxidized or broken down to get energy?
the fuel (such as glucose)
What molecule starts the krebs cycle?
pyruvate
This stage of cellular respiration breaks down glucose into two molecules of pyruvate:
glycolysis
This stage of cellular respiration completes the breakdown of glucose:
krebs cycle
Where does glycolysis happen in a cell?
cytoplasm
Where is the electron transport chain located?
inner mitochondrial membrane
Where does the krebs cycle happen in the cell?
in the mitochondrial matrix (innermost part)
What is the name of the protein enzyme that ha H+ moving back across the membrane?
ATP Synthase
What products are made in cellular respiration, that we breathe out?
CO2 and water
How much gross and net ATP is made in glycolysis?
4 gross, and 2 net (since we use 2 in the process)
What 3 major products are made in the krebs cycle
ATP, NADH, and FADH2
What gets pumped into the inner mitochondrial membrane during the ETC?
H+ ions
This is the method of converting pyruvate to ethanol in two steps:
alcohol fermentation
to make electron carrier for the ETC (NADH and FADH2)
About how many ATP does the ETC make?
30-34 ATP
Why are H+ ions pumped into the inner mitochondrial membrane in the ETC step?
To create a natural concentration gradient so we can make ATP
Do fats or carbs produce more ATP?
fats
