A large variety of proteins adapt their shape to recognize their molecular partners. Among these, calmodulin (CaM) is probably the most prototypical example (1): this protein, which acts as a Ca2+ messenger in all eukaryotic cells, recognizes more than 100 different protein partners involved in...
Which neutral atom has the same number of electrons as a Ca2+ ion? Which elements in the periodic table constitute the alkali metals? 1. How many elements are on the periodic table? 2. Which of those are: a. metal? b. gas? c. unknown?
a. Ca2+ b. Sr2+ c. K+ Put the following in order of increasing atomic radius. a. K+ b. Se2- c. S2- As the elements of Group 1 on the periodic table are considered in order of increasing atomic radius, the ionization energy of each successive element generally: ...
Why does Cl- have a larger ionic radius than Ca2+ ? Explain the trend in melting point of metals across period 3 elements. Explain why metals tend to be oxidized and nonmetals tend to be reduced. Describe briefly why the study of electromagnetic radiation has been important for...
When moving from top to bottom in a group of the periodic table, do the elements become more or less metallic? In the vertical columns of the periodic table: a. Atomic weight increases from top to bottom. b. Outer shell electrons increase from top t...
The simulations box contained the peptide, 72 lipid-A and roughly 15000 water molecules, Cl− anions to neutralize the peptide charge (two for TempL, three for Q3K-TempL) and 72 Ca2+ cations to neutralize the lipid-A. The starting configurations, with the peptide embedded into the bilayer...
