Question

1)

ATP is primarily generated by which organelle?

	a.	nucleus
	b.	mitochondria
	c.	lysosome
	d.	gogli

2)

Which of the following is an example of a serine threonine kinase?

		Jak - STAT receptor
		TGF - beta receptor
		Insulin receptor
		Cortisol receptor

3)

Facilitated transporters:

		will bind any compound and are therefore not unique
		are considered a type of active transport.
		transport molecules against a concentration gradient.
		can be inhibited by compounds that block their binding site

4)

The insulin receptor is part of which family of receptors:

	a.	GPCR
	b.	Steroid hormone receptor.
	c.	Threonine kinase
	d.	Tyrosine kinase

Answer 1

1. mitochondria

2.TGF - beta receptor

the TGF-beta receptor is a classic example of a serine threonine kinase.The Smad family proteins are phoporalated

and activated down steam of these receptor.

3.

can be inhibited by compounds that block their binding site.

facilitated transporters are specific to certain ligands adn transport molecules along a concentration gradient and are there fore consider to be a form of positive transport.Theycan be inhibited by compounds that block their binding site

4. Threonine kinase

The insuline receptor is an example of Threonine kinase. upon insuline binding there is an auto phosphorylasation
