hypothesis correct answer: a well framed statement that can be tested, falsifiable, and replicated independent variable correct answer: The experimental factor that is manipulated; the variable whose effect is being studied. dependent variable correct answer: the variable that changes in response to manipulations of the independent variable. control group correct answer: the group that is not exposed to the treatment experimental group correct answer: the group that is exposed t...

Catalyst - ANSWER-a substance that increases the rate of a chemical reaction without being consumed Enzyme - ANSWER-a molecule that increases the rate of a chemical reaction without being consumed (ex: protein) Activation energy - ANSWER-amount of energy required to convert a substrate into a product Active site - ANSWER-location on an enzyme that physically interacts with the substrate How do enzymes catalyze reactions? - ANSWER-1. substrate attaches to active site 2. activation en...

How do enzymes catalyze reactions? - ANSWER-An enzyme is added to the reactant side of a chemical reaction, and produces an increase in the reaction rates 7 properties of enzymes - ANSWER-o Substrate specific o Not destroyed o Used genes to determine how many are needed o Increase reaction rates o Decrease activation energy o Protein catalysts How do inhibitors work? - ANSWER-A substance that slows down or prevents a particular chemical reaction or other process, or reduces the activi...
