Quiz zum Vortrag

  1. They change shape when binding occurs.
  2. They are always membrane bound.
  3. They change shape on binding to another receptor.
  4. They require co-factors to be stimulated.
  5. They are specific to a single type of substance.
  1. They use covalent interactions to modify proteins.
  2. They use hydrogen interactions to modify proteins.
  3. They carry messages out of cells.
  4. They use van der Waals forces to modify proteins.
  1. Inositol-1, 4, 5-triphosphate
  2. Deoxyribose nucleic acid
  3. cAMP
  4. cGMP
  5. Ca+2 ions
  1. Covalent changes in protein molecules.
  2. Hydration of protein molecules.
  3. Dehydration of protein molecules.
  4. Conversion of triple bonds to double bonds between the 2 carbon atoms of a protein molecule.
  5. Conversion of triple bonds to single bonds between the 2 carbon atoms of a protein molecule.
  1. An activated phospholipase C enzyme catalyzes the breakdown of the PIP2 molecule to IP3 and DAG.
  2. Phospholipase C protein acts as a second messenger that directly stimulates the gene expressions by binding with the DNA molecules.
  3. Phospholipase C protein acts as a second messenger molecule for the synthesis of PIP2 from DAG and IP3.
  4. Phospholipase C acts as an energy source for the transduction of extracellular response toward the Golgi apparatus.
