Topic 8 Flashcards
Enzyme inhibition
Controls metabolic pathways and prevents unnecessary production
Competitive inhibition
Inhibitor molecules compete with the substrate to occupy the active site
Non-competitive inhibitor.
Inhibitor molecule binds at the allosteric site, which is away the active site. Causes changes in the shape of the enzyme active site.
End product inhibition
When the end product acts as a noncompetitive inhibitor.
Threonine to isoluecin
Threonine undergoes a 5-stage reaction. When it produces isoleucine, it binds to the allosteric site in reaction 1, preventing the conversion of isoleucine.
Products of aerobic respiration
CO2 and water
Products of anaerobic respiration
CO2 and ethanol in yeast
CO2 and lactate acid in humans.
Oxidation
The loss of hydrogen atoms
Reduction
The gain of hydrogen atoms
Carboxylation
The addition of carbon dioxide
Phophorilization
The addition of phosphate
Glycolisis
Occurs in the cytoplasm and converts glucose into 2 pyruvates
Link Reaction
Occurs in the matrix, and converts each pyruvate into acetyl-CoA.
Krebs cycle
Occurs in the matrix, Converts each acetyl into 6 carbon molecules.
Electron transport chain
Occurs in the inner membrane, and transforms all the NADH and FADH2 produced into ATP.
