How much energy is released from original glucose molecule
10% from a anaerobic reaction of glycolysis
To get more energy what needs to happen
Additional metabolic pathways need to help out
Pyruvvate –> Acetyl CoA which entres what
Kreb cycle
What are the methods to synthesise ATP
Substrate level phosphorylation Oxidative phosphorylation
Kreb cycle is what
Aerobic ATP production
Define krebs cycle
Completes the oxidation of substrates and produces NADH and FADH2 to entre the electron transport chain
what does the electron transport chain have,
oxidative Phosphorylation
What are removed from NADH and FADH2 are passed along a series of carriers to produce ATP
Electrons
Catalyses conversion of pyurvate to Acetyl - CoA occurs where
Inter mitrochondria membrane
An irreversible reaction for Acetyl - CoA to pyruvate
Determines if pyruvate entres the cycle –> guards the door to the cycle
What is the kreb cycle
Cyctical series of reactions that oxidise 1 molecule of acetyl-coa to 2 X co2 generating energy cycle is aerobic
What do all cells have to help with energy
Mitochondria
Where are enzymes free
Mitochondiral matrix
What is the only enzyme that is not in the mitochondiral matrix
Succinate dehydrogenase
What is the function of the krebs cycle
Final pathway for oxidation of carbs fats and proteins since glucose, fatty acids and amino acids are metabolised to acetyl - coa or to another intermediantes in the cycle
What is the main function of the kreb cycle
To produce energy
What type of energy is produce in the kreb cycle
ATP or in NADH or FADH through the ETC
How does the kreb cycle operate
Anabolically and catabolically
What is the first stage of the krebs cycle
Attachment of Acetyl - CoA to the oxalocetate carrier
What is the second stage of the krebs cycle
Break up of carriers
What is the third stage of the krebs cycle
Regeneration of carrier oxaloacetate
What 3 enzymes are used in the krebs cycle
• citrate syntase • isocitrate dehydrogenase • A - ketoglutarate dehydrogenase
What is the primary site for ATP synthesis
Electron transport chain
What does the ETC require
Oxygen
