What NON-CATALYTIC residues in the active site of the enzyme are most likely important for function? a. Highlight three highly conservative residues, show both structural interactions AND conservation using PyMol and JalView. Hypothesize why they are critical for function, using language from the lecture.
b. Highlight one low conservation residue, show both structural interactions AND conservation using Pymol and JalView. What other amino acids are observed, hypothesize why the alternate residues are ok.

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.

explanation:

a polar bond is formed when electrons are shared unevenly between atoms
