Question
Chapter 6, Problem 52FB
Summary Introduction
To review:
The given blank space in the statement “The ____________________ model states that substrate binding causes enzymes to undergo conformational change. ”
Introduction:
An enzyme is a compound, mainly protein, which catalyzes the reaction by increasing the rate of reactionand by lowering the activation energy(required for a reaction). An enzyme has an active site, which gets bound with the substrate and leads to the formation of the product.

- Hexokinase is an example of a general class of enzymeknown as the _____________________.arrow_forward_____________ allosteric effects of enzymes involve ligands that are different from substrate molecules.arrow_forwardSuicide substrates are molecules that resemble the substrate. When these molecules enter into the active site, they form a covalent bond with the enzyme, thereby permanently inhibiting it. These molecules have been used to label the amino acid side chains that are involved in the catalytic reaction occurring within the active site. This is usually accomplished by hydrolyzing the inhibited enzyme. How could an investigator identify the amino acid bound to the suicide substrate molecule?arrow_forward
- Since KM is an intrinsic property of an enzyme, its value does not depend on the enzyme concentration. True or Falsearrow_forwardEnzymes are stereochemically specific; that is, they oftenconvert only one stereoisomeric form of substrate intoproduct. Why is such specificity inherent in theirstructure?arrow_forwardSuggest a reason why heating a solution containing an enzyme markedly decreases its activity.
