Enzyme Quest - Terms To Know

Question 1

• ATP

Answer 1

adenosine triphosphate: energy currency of a cell

Question 2

• Activation energy (EA)

Answer 2

energy to cause a chemical reaction

Question 3

• Active site

Answer 3

region of enzyme where substrate binds and where catalyzed chemical reactions take place

Question 4

• Allosteric

Answer 4

regulation of enzyme activity through binding of regulatory molecule at a site other than enzyme active site

Question 5

• Anabolic

Answer 5

reaction in living organisms causing growth in molecules

Question 6

• Catabolic

Answer 6

set of metabolic process in living organisms involved in breaking down complex molecules into simpler ones releasing energy in ATP form

Question 7

• Catalyst

Answer 7

substance that increases rate of chemical reactions without getting consumed

Question 8

• Coenzymes

Answer 8

organic molecules that help enzyme activity like Vitamins or molecules obtained from vitamins

Question 9

• Cofactors

Answer 9

inorganic molecules that help enzyme activity

Question 10

• Chemical potential energy

Answer 10

potential energy in bonds of molecule

Question 11

• Competitive inhibitor

Answer 11

compete with substrate for binding to active site

Question 12

• Non - competitive inhibitor

Answer 12

allosteric site changes shape affecting active site. Enzymes can’t bind substrate

Question 13

• Endergonic

Answer 13

potential energy level of reactants is lower than product energy level. Energy goes in

Question 14

• Exergonic

Answer 14

potential energy level of reactants is higher than products. Energy is released

Question 15

• Enzyme

Answer 15

specific protein controlling rate that chemical reactions happen in living orgamsms without being used up

Question 16

• Enzyme -Substrate complex

Answer 16

substrate temporarily goes to enzyme

• Isomerases

Answer 20

rearrangement of atoms in molecules

Question 21

• Ligases

Answer 21

energy from ATP breaking is used to join 2 molecules

Question 22

• Lyases

Answer 22

removal of atom groups without hydrolysis

Question 23

• Metabolism

Answer 23

all reactions in living organisms

Question 24

• Oxidoredustares

Answer 24

oxidation reduction: oxygen or hydrogen are gained or lost
