Resumen del Recurso

Pregunta 1

Pregunta
Once tyrosine kinase is activated, which protein binds?
Respuesta
  • Phospholipase Cgamma
  • Phospholipase Cdelta
  • Phospholipase Calpha

Pregunta 2

Pregunta
How does tyrosine kinase activate phospholipase cX?
Respuesta
  • No, really, how'd you think? What else could it POSSIBLY BE
  • Phosphorylation

Pregunta 3

Pregunta
What is the function of Phospholipase Cgamma?
Respuesta
  • PIP3 breakdown
  • PIP2 breakdown
  • PIP breadown

Pregunta 4

Pregunta
What happens to phospholipase cX when it binds to T.K?
Respuesta
  • It is phosphorylated
  • It's dephosphorylated

Pregunta 5

Pregunta
Name the products of PIP breakdown
Respuesta
  • IP3
  • DAG
  • No seriously, how many times have we covered this protein family?

Pregunta 6

Pregunta
What subunit allows Phospholipase Cgamma to be recruited to the phosphorylated tyrosine kinase?
Respuesta
  • SH3
  • SH2
  • SH4

Pregunta 7

Pregunta
Most of the phospholipase cgamma's effects are the same as phospholipase Cbeta, which one is different?
Respuesta
  • PKC activation causes the activation of Na+/H+ pumps
  • PKC activation causes the activation of Na+/K+ pumps
  • PKC activation causes the activation of Na+/Cl- pumps

Pregunta 8

Pregunta
What is the effect of the membrane pump activation?
Respuesta
  • Cell becomes more alkaline
