Describe how enzymes catalyze chemical reactions without being used up. Explain how enzymes help to control metabolism in living organisms. Be sure to discuss what enzymes are composed of and how their structure affects their function. How do enzymes affect reactio...
These methods describe both the quantization of vibrational modes as well as tunneling and are applied to the ⋅H + H2and ⋅H + CH4reactions. The absolute rate constants computed with the semiclassical instanton method both using on-the-fly electronic structure calculations and fit...

Many of these theories sought to describe light as a ray -- a straight line moving from one point to another. Pythagoras, best known for the theorem of the right-angled triangle, proposed that vision resulted from light rays emerging from a person's eye and striking an object. Epicurus ...
Write a balanced chemical reaction to show how \text{NO}_2 reacts with water and oxygen in the atmosphere to form nitric acid. Write a balanced chemical equation including phases) to describe the following reactions of sulfuric acid and nitric acid a. Nitric acid reacts w...
Whereas the extent of these conformational changes has been correlated to the level of TCR–pMHC catch bonds4,6,22, the two have not been integrated into a mathematical model to explore their potential connection. Here we develop two such models, one for each MHC class, to describe both α...
Describe the function of enzymes in biological reactions. Can an enzyme or catalyst catalyze more than one reaction? How are enzymes involved in catabolic and anabolic processes? What is the activation energy of a chemical reaction, and how does an enzyme allow this obstacle to be overcome much...
Consider the following reaction: 2NOCl(g) + Delta H rightleftharpoons 2NO(g) + Cl2(g) For each stress applied at time t1, t2, and t3 on the graph, describe using Le Chatelier's Principle, what shift has occurred, and what stress could have resulted in tha ...
