Krebs Cycle
very common pathway
Starts with pyrubic acid
Summary: 3 pyrubic acid now converted to 3 CO2
1 ATP-substrate level phosphorolation
FADH2=1
NADH2=4
building blocks
Fermentation
partial oxidation of glucose, form stable organic end products --- usually acids, alcohol, and gas, do not use oxygen use the Krebs cycle and electron transport
Emergy electrons are used to
pump protons across the membrane
outside = + inside = -
Electron Transport System
most ATP produced here
Series of conezyme embedded
Pass Hydrogen and electron from one to another (donated by NADH2 and FADH2) --- eventually passed to final accelerator (O2 - H2O) aerobic respiration Some coenzymes can carry H others carry only electrons
NADH + H --- NAD
(aerobic respiration - electron transport system) oxidation of NADH+H occurs by reducing pyrubic acid or a product of pyrubic acid --- stable end products that are organic
Hydrogen can only enter the cell at certian points
they return across the membrane --- Hydrogen reenters ATP produced
NADH = 3 ATP
FADH = 2 ATP
Glycosis
2 ATP --- substrate level phosophorolation
