Enzymes

  1. Anabollic vs anabollic
    Anabolic also exergonic reactions release heat (it also breaks down polymers/large materials. Polymer to monomers) while anabolic/endergonic reactions absorb heat. (Synthezise small to large. Monomers to polymer)
  2. What is ATP?
    Adenosine triphosphate, this is a universal energy across all living things. Formed tru ADP Adenosine diphostpahte plus  inorganix phosphate 1
  3. What is the structure of ATP? What repels and creates energy?
    The backbone of ATP is an Andenine plus ribose so the Andenosine backbone is then attached with 3 Phosphates. Adenosine Triphosphate. The phosphates constantly repel each other and alot of enegery is released when one phosphate is remvoed ATP to ADP + Energy.
  4. What is Dephosphorylation and Phosphorylation?
    Dephosphorylation is when you remove one phosphate to drive a reaction and phosphorylation is when you add/regen a phosphate to ADP
  5. What are enyzmes and metabolic reactions?
    Are special types of proteins used to help speed up metabolic reactions without being consumed themselves. (catalylists)Metabolic reactions occur natrually in your body but take a long time. Enyzmes speed up processes by lower enegery requiments.
  6. What is te process of Reactants to products with the help of enzymes called?
    • Metabolic pathway. Often need multiple enzymes. 
    • Sub one/enzyme one to Sub two/enzyme two etc
  7. What are enzyme names and examples?
    • They are names that mostly end with ASE named after the substrate they bind with.
    • EX: Maltose=MaltASE
    • Sucorse+SucrASE
    • Lactose=LactASE
  8. What is a substrate and Active site? What can enzymes carry out? (processes)
    • A substrate is the substance that the enzyme is reacting with/ being changed by. Active site is where the site of reaction is.
    • They can carry out Dehy sythesis and hydrolysis.
  9. Lock and key vs Induced fit model?
    Lock and key (outdated) is where active site and subrate perfectly join. Induced fit (current) active site changes size to accomodate substrates.
  10. What are Cofactors and Coenzymes?
    • Cofactors bind to the enzyme to activate it. Usually Cation ions. INORGANIC
    • Coenzymes directly bind to active site at the same time that substrates do. ORGANIC molecules.
  11. Name some effects on Enzymes? What kills/what helps
    Enzymes can denature or coagulate from temperature, PH and competitive inhibitors. However, they can thrive with more concentrations of both enzymes and substrates.
  12. How does temp effect an enzyme
    Hotter environments to a degree can speed up things resulting in more collisions with eznymes so more efficient.
  13. Competitie inhibitors on enzymes. effects?
    They compete for active sites against substrates. They can clog/destroy enzymes. Usually carbon monoxide or cynaide
  14. What does more concentration fo substrates and enzymes lead to?
    More SAT=MORE collisions
  15. What is Allosteric activity?
    • Whether an enzyme is off/on
    • It could be Allosteric inhibition where the presence of a molecule can show that an enzyme is not needed (enough end product)
    • Or it could be Allosetic Activation where the presence of a molecule indicates that the enzyme is needed for metabolism. (too much substarte need end product)
  16. What is metabolism?
    Term to describe reactions in your body. Reactants to prodcts.
