Enzymes

Question 0

Catabolism

Answer 0

Breakdown process in metabolic pathways that releases energy

Question 1

Metabolism

Answer 1

All chemical reactions and energy changes involved in them

Question 2

Anabolic pathways

Answer 2

Buildup/synthesis of metabolic pathways (USES ENERGY)

Question 3

Thermodynamics

Answer 3

Study of energy transformation

Question 4

Entropy

Answer 4

Means disorder

Living systems increase entropy in the universe-> energy is used to maintain order

Question 5

Exergonic

Answer 5

RELEASES free energy

Question 6

Enogonic

Answer 6

Absorbs free energy

Question 7

ATP

Answer 7

Adenine +ribose+ 3 phosphate groups

Releases energy through hydrolysis (becomes ADP)

Drives endergonic reactions

Question 8

Catalyst vs enzymes

Answer 8

A catalist can be anything, enzymes must be proteins and are very specific

Question 9

EA

Answer 9

Activation energy

Question 10

Enzyme reactions

Answer 10

Substance binds to active site, heald there by weak bonds

Active site acts as a template and provides a favorable micro environment

Question 11

Competitive inhibitors

Answer 11

A substance fits into the active site on the enzyme and prevents the substrate from entering the site

Question 12

Non competitive inhibitors

Answer 12

Substances that attach to a different site on the enzyme but change is shape so the active site no longer fits

Question 13

Feedback inhibition

Answer 13

Shuts down pathway when enzyme process is over
