Genetic control
________ is exercised by regulation of the synthesis of enzymes specific to the stage of life and need of the organism.
Reaction rate
________ is maximal at a pH that reflects the pH of the enzymes site of action in the body.
Competitive
________ (enzyme) inhibition is the enzyme regulation in which an inhibitor competes with a substrate for binding to the enzyme active site.
Enzymes act
________ as catalysts because of their following abilities to:
active site
Within the folds of an enzymes protein chain is the ________- the region where the reaction takes place.
Coenzyme
________ is an organic molecule that acts as an enzyme cofactor.
Cofactor
________ is a nonprotein part of an enzyme that is essential to the enzymes catalytic activity; a metal ion or a coenzyme.
Inhibition
________ (of an enzyme) is any process that slows or stops the action of an enzyme.
Feedback control
________ is the regulation of an enzymes activity by the product of a reaction later in a pathway.
Vitamins
________ are organic molecules required in small amounts in the body that must be obtained from the diet.
inactive forms
Some enzymes are synthesized in ________ that differ from the active forms in composition.
Minerals
________ are chemical elements needed in small amounts in the diet.
Enzymes
________ are catalysts that accelerate the rates of biochemical reactions but at the end of the reaction remain unchanged themselves.
Minerals function
________ as macronutrients (calcium and phosphorus for bone), electrolytes, and micronutrients used primarily as enzyme cofactors.
shapes of protein
The substrate is first drawn into position by the same kinds of noncovalent forces that govern the ________ molecules.
reaction rate
In the presence of excess substrate, ________ is directly proportional to enzyme concentration.
turnover number
the maximum number of substrate molecules acted upon by one molecule of enzyme per unit time.
