Krebs cycle
- Involves series of oxidation-reduction reactions
- Occurs in matrix of mitochondria
- 2C acetylCoA from link reaction
combines with 4C to produce 6C
molecule
- 6C molecule loses CO2 and Hs to
give a 4C molecule and single ATP
produced as a result of Substrate-level phosphorylation
- 4C molecule combines with new molecule
of acetylCoA to begin new cycle again
- 4C molecule combines with new molecule
of acetylCoA to begin new cycle again
- 6C molecule loses CO2 and Hs to
give a 4C molecule and single ATP
produced as a result of Substrate-level phosphorylation
- For each molecule of pyruvate(of 2
produced from glucose) together with
link reaction produces
- Reduced coenzymes: NAD and FAD
Anotações:
- Has potential to produce ATP
- 1 ATP
- 3 CO2
- Reduced coenzymes: NAD and FAD
- Coenzymes-molecules that some
enzyme require in order to function
- They carry H atoms from one
molecule to another
- NAD in respiration works with
dehydrogenase enzyme- catalyse the
removal of H ions from substrates and
transfer them to other molecules;H carriers
- They carry H atoms from one
molecule to another
- Breaks down macromolecules into smaller
ones;pyruvate=>CO2
- Produces H atoms that are carried
by NAD to the electron transport
chain for oxidative phosphorylation
- Leads to production of ATP
- Leads to production of ATP
- Regenerates the 4C molecule
that combines with
acetylCoA(otherwise it would
accumulate)
- A source of intermediate
compounds used by cells in the
manufacture of other important
substances(fatty acids,amino
acids, chlorophyll)
