Enzymes and Biochemical Reaction Vocab

Question 1

mostly specialized proteins that speed up biochemical reactions by lowering activation energy

Answer 1

enzymes

Question 2

a region on an enzyme that binds to a protein or other substance during a reaction

Answer 2

active site

Question 3

All of the chemical reactions that occur within an organism

Answer 3

metabolism

Question 4

the breaking and forming of bonds between different substances during chemical changes

Answer 4

chemical reaction

Question 5

breaking down of larger molecules from simpler compounds ones> a release of energy = exergonic

Answer 5

catabolic

Question 6

the amount of energy that needs to be absorbed for a chemical reaction to start

Answer 6

activation energy

Question 7

the substances changed during a chemical reaction

Answer 7

reactants (substrates)

Question 8

the substances made by a chemical reaction

Answer 8

products

Question 9

absorbs energy in the form of heat or light

Answer 9

endothermic

Question 10

releases energy in the form of heat or light

Answer 10

exothermic

Question 11

when an enzyme’s active site gets deformed and looses its specific shape> loss of biological activity

Answer 11

denaturation

Question 12

build larger molecules from smaller ones > requires consuming energy to do it = endergonic

Answer 12

anabolic

Question 13

substances that speed up a chemical process without actually changing the products of reactions

Answer 13

catalyst
