The phosphorylation of proteins by enzymes called kinases is an important intracellular event. when bound by their ligand, which of the following class(es) of receptors cause an increase in cellular kinase activity?

a. ligand-gated ion channelsb. receptor kinasesc. receptor kinases and g protein-coupled receptorsd. g protein-coupled receptors

A

Explanation:

Ligand gated ion

It increases the effect of a single ligand, and integration allows the signal to be incorporated into another biochemical pathway

a

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
