Some enzymes require additional to catalyze reactions effectively. These could be small organic molecules or ions Question 8 7.5 pts In order to avoid wasting cell resources, feedback mechanisms to regulate enzyme activity are feature of Allostery Kinetics Thermodynamics Metabollum Select all the true statements about sequential versus concerted models of allostery C) Insenti altery.bading of the substrate on one end of an enzyme causes a conformational change on the other end which propagates to another one and enables con binding of a second substrate to the second enume No conformational changes in the model In concertelostery, the two forms of the enzyme exist in equilibrium because of a conformational change independent of substrate binding In concerted allostery binding of the substrate to one of the forms is favorable but not to the other and hinding of the second substrates enhanced on the favorable for What roles do enzymes play in nature? They have a role in metabolic reactions They increase rates of reaction but do not shift the equilbrium formed between products and reactants They catalyze cellular processes All of the above
