Questão 2

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

Questão 3

Questão
What is the function of Phospholipase Cgamma?
Responda

  • SH2
  • SH4

Questão 7

Questão
Most of the phospholipase cgamma's effects are the same as phospholipase Cbeta, which one is different?
Responda
  • 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

Questão 8

Questão
