In the PhET Reactions & Rates (http://openstaxcollege.org/I/16PHETreaction) interactive, on the Many Collisions tab, set up a simulation with 15 molecules of A and 10 molecules of BC. Select “Show Bonds**#x201D; under Options.
(a) Leave the Initial Temperature at the default setting. Observe the reaction. Is the
(b) Click “Pause" and then “Reset All,” and then enter 15 molecules of A and 10 molecules of BC once again. Select “Show Bonds" under Options. This time, increase the initial temperature until, on the graph, the total average energy line is completely above the potential energy curve. Describe what happens to the reaction.

- 4. Refer to the data below to answer the following questions: The octapeptide saralasin is a specific antagonist of angiotensin II. A derivative of saralasin is used therapeutically as an antihypertensive. Amino acid analysis of saralasin show the presence of the following amino acids: Ala, Arg, His, Pro, Sar, Tyr, Val, Val A.Sar is the abbreviation for sarcosine, N-methyl aminoethanoic acid. Draw the structure of sarcosine. B. N-Terminal analysis by the Edman method shows saralasin contains sarcosine at the N-terminus. Partial hydrolysis of saralasin with dilute hydrochloric acid yields the following fragments: Tyr-Val-His Sar-Arg-Val His-Pro-Ala Val-Tyr-Val Arg-Val-Tyr What is the structure of saralasin?arrow_forwardWhat is the structure of the DNA backbone?arrow_forwardPLEASE PLEASE PLEASE use hand drawn structures when possarrow_forward
