True or False: For every kinase there is an equal and active phosphatase correct answer: True Name one example of a protein signal correct answer: Epinephrine Name one small molecule signal correct answer: Acetylcholine or cortisol What are three essential parts of a signaling cascade? correct answer: Initial signal, Binding, and Termination How is a signal turned off? correct answer: Phosphorylate/Dephosphorylate or signal degradation What is a second messenger? correct answ...

In the Background section, it is noted that inhibition of protein synthesis blocks cell division in sea urchins. This observation implies that: - new proteins must be made for cell division to occur. Why did the researchers choose sea urchin embryos to study cell division? - Sea urchin embryo cells divide rapidly by mitosis. In the gel, the amount of protein can be determined by: - the intensity of the band. In the gel, proteins migrate different distances based on: - their size and charge....
