Cellular respiration Flashcards
Ex explain Glycolysis
- A molecule of glycoast is converted into a new six carbon compound
- The new six carbon compounds split into two molecules of PGAL (2 ATP are used to start this reaction)
- the two PGAL molecules are oxidized to produce two new three carbon compounds
- The new three carbon compounds are converted into two molecules of pyruvic acid.( this produces four a t p, leaving this reaction with a net positive of 2)
Explain the krebs cycle
- Acetyl CoA Combined with oxaloacetic acid to produce citrus acid
- Citrus acid releases a co2 molecule to form a five carbon compound ( producesNADH)
- THE 5 CARBON COMPOUND RELEASES CO 2 MOLECULE TO FORM A 4 carbon COMPOUND? ( this produces an ATP AND NADH)
- THE FOUR CARBON COMPOUND IS CONVERTED INTO A NEW FOUR CARBON COMPOUND ( this produces A. FADH2)
- the new four carbon compounds are converted back into oxalacetic acid. Starting the cycle against
The FADH2, NADH, is used electron transport system
What happened to the pyruvic acid after the glycolysis
Pyruvic acid combines with coenzyme A to form Acetyl CoA. CO2 NADH AND H+ are also produced in this reaction
Explain the electron transport system
NADH AND FADH2 supply electrons and protons for the electron transport chain. The electrons are passed along a chain of acceptor molecules that release energy each time (ato) , in the final acceptor, there is oxygen.
That accepts the energy. This makes water
What is the bounce equation for cellular respiration
C6H12O6 + 6O2 = 6O2 + 6H2O + ENERGY
What happens if there is a lack of oxygen after breaking down the glucose
If there is no oxygen, then anaerobic respiration will start, which is also known as fermentation.
This will produce lateric acid. Which is used in food manufacturing
This is also how to make alcohol
