AP Bio Chapter 6

Question 1

energy

Answer 1

ability to do work or bring about change.

Question 2

Kinetic energy

Answer 2

motion

Question 3

Potential

Answer 3

stored energy

Question 4

chemical energy

Answer 4

food energy- composed of organic molecules

Question 5

mechanical energy

Answer 5

conversion of chemical energy into motion

Question 6

law of thermodynamics

Answer 6

energy cannot be vreated or destroyed only changed from one form to another
conversion of energy is never 100% effective-loss of usable energy

Question 7

entropy

Answer 7

disorganization

Question 8

free energy

Answer 8

energy left to do work after a chemical reaction

Question 9

exergonic

Answer 9

spontaneous, releases energy has a positive delta G- example Cell Resp

Question 10

endergonic

Answer 10

requires energy- negative delta G

Question 11

Metabolism

Answer 11

sum of all the chemical reactions in a cell

Question 12

coupled reaction

Answer 12

needs ATP and produces ATP

Question 13

enzyme

Answer 13

speed chemical reactions without being affected by the reaction, a protein

Question 14

ribozymes

Answer 14

made of RNA instead of proteins

Question 15

metabolic pathways

Answer 15

series of linked reactions

Question 16

substrate

Answer 16

reactants in enzymatic reactions

Question 17

active site

Answer 17

place of chemical reaction

Question 18

induced fit

Answer 18

enzyme changes slightly to fit substrate

Question 19

factors that change enzyme productivity

Answer 19

amount of substrate, amount of enzymes, PH, temperature, co factors, inhibition

Question 20

denature

Answer 20

change in shape

Question 21

co factors

Answer 21

inorganic ion or non protein at the active site that makes it work properly

Question 22

co enzyme

Answer 22

non protein organic molecules

Question 23

vitamins

Answer 23

co enzymes needed in peoples diets

Question 24

inhibitions

Answer 24

limit enzyme activity

Question 25

noncompetitive

Answer 25

changes shape by inhibitor attaching to allosteric site

Question 26

allosteric site

Answer 26

location of non competitive inhibitor

Question 27

competitive

Answer 27

competes for active site blocking it

Question 28

redox reaction

Answer 28

equation that has bothside being reduce and oxidized

Question 29

reduction

Answer 29

GER gain of electrons-oxidizing agent

Question 30

Oxidation

Answer 30

LEO loss of electrons- reducing agent
