cell respiration flashcards
overall formula for cellular respiration
C6H12O6 + 6O2 -> CO2 + H2O + ATP
reactants of cellular respiration
Glucose and Oxygen
products of cellular respiration
Carbon dioxide, water, and ATP
What happens in process of glycolysis
glucose is split into pyruvic acid producing small amounts of NADH and ATP
is glycolysis anaerobic or aerobic
anaerobic
where does glycolysis occur
cytoplasm
how efficient is glycolysis
not a very efficient process
what is the net gain of ATP
2% gain
After glycolysis if O2 is not present, which process will occur next
fermentation
The 2 types of fermentation
Lactic Acid and Alcoholic
How are the 2 types of fermentation different
Lactic acid fermentation makes lactic acid and alcoholic fermentation makes ethanol and carbon dioxide
why does fermentation occur if no atp is produced
it uses other forms of energy in the process of glycolysis
what are the uses of Alcholic fermentation in the kitchen
yeast
Where does krebs cycle occur
Matrix
Where does the ETC occur
Matrix
what determines if a cell goes through fermentation or cellular respiration
oxygen
What is the intermediate molecule that goes into the krebs cycle
Acetyl CoA
what is the main point of the Krebs Cycle
Create NADH and FADH
Why is the Krebs cycle also called the Citric Acid Cycle
It is the first product formed in the cycle
What happens during the ETC
The etc will take the H off of NADH and FADH2, and turn them back into NAD and FAD
Why do we need oxygen
To breathe
What is the efficency of the ETC
39%
What is O2 debt
when someone consumes oxygen at a faster rate than it can be replaced, leading to a deficit in O2 which cause increased respiration as the body attempts to replace the used oxygen
How long does it take to use up all the glucose in our blood stream
20 minutes
Then what do we start doing for energy
metabolizing fats into 9 pyruvic acid
How is cellular respiration and photosynthesis closely linked
photosynthesis makes glucose which is used in cellular respiration for making ATP
why is oxygen needed in cellular respiration
pyruvic acid is broken down and NADH is used to make large amounts of ATP
What is ATP synthase
enzyme that synthesizes ATP in the mitochondrial inner membrane
What is chemiosmosis
the movement of ions across semipermeable membrane bound structure
What is the Function of NADH & FADH2?
Carry their electrons to the ETC
