Occasionally the “delicate” nature of enzymes is referred to. Explain why this adjective is appropriate.
Which of the following describe what enzymes such as Chymotrysin accomplish to allow products to form and be released by the enzyme active site?
Group of answer choices
catalyze chemical eactions that are thermodynamically unfavorable to occur
establish a more stable transition state at a higher energy level to perform a catalysis reaction
redce the chemical energy held within a chemical bond
modify chemical structure of a substrate to "fit" within the active site
The diagram shows the mechanism of a general enzyme‑catalyzed reaction. Put the labels in the correct locations.
The abbreviations E, P and S indicate the enzyme, product, and substrate, respectively.
