Populations have growth limits

Categorize these limits as being either density independent or density dependent.

TLS Online TPP Program

#Id: 9655

#XL - T Zoology

Feedback regulation by MAP Kinase

Phosphorylation of threonine residue in HER1 decreases the ability of the receptor kinase to become fully active.

#XL - T Zoology

Feedback regulation by MAP Kinase

Active MAP kinase phosphorylates Raf on multiple sites, reducing its association with Ras.

TLS Online TPP Program

#Id: 9657

#XL - T Zoology

Negative feedback regulation by MAP Kinase

activated MAP kinase triggers an increase in the expression of dual-specificity phosphatases (DUSPs), particularly DUSP6.

#Id: 9658

#XL - T Zoology

Hormonal stimulation of GPCR leads to the activation of PLC (IP3/DAG pathway).

TLS Online TPP Program

#Id: 9659

#XL - T Zoology

GPCRs specifically activate the β isoform of PLC (PLCβ)

TLS Online TPP Program

#Id: 9660

#XL - T Zoology

Many RTKs and cytokine receptors specifically activate the γ isoform (PLCγ), which contains an SH2 domain.
