enzymes

Question 1

what are enzymes

Answer 1

enzymes are proteins that speed up chemical reactions by lowering the activation energy needed

Question 2

activation

Answer 2

energy needed to start a chemical reaction

Question 3

catalyst

Answer 3

a substance that speeds up chemical reaction

Question 4

substrate

Answer 4

the molecule that an enzyme binds to

Question 5

active site

Answer 5

special part of the enzyme where the substrate binds

Question 6

endothermic

Answer 6

absorbs energy

Question 7

exothermic

Answer 7

releases energy

Question 8

tempature

Answer 8

temperature will increase the rate of a reaction until the temp. is too high and denatures the enzyme

Question 9

pH levels

Answer 9

a pH that is too high or low will cause an enzyme to denature and no longer work

Question 10

denature

Answer 10

lose its shape

Question 11

inhibitors

Answer 11

inhibitors can bind to an enzyme and prevent the substrate from properly binding

Question 12

adp became atp when a phospate group is added

Question 13

nitrogen base

Answer 13

adenine

Question 14

sugar ring

Answer 14

ribose

Question 15

when atp is broken down, it

Answer 15

releases energy

Question 16

atp = adp + p + energy

Answer 16

exothermic reaction

Question 17

adp + p + energy = atp

Answer 17

endothermic reaction

Question 18

carbohydrates

Answer 18

most commonly broken down for atp. 36 atp from 1 glucose

Question 19

lipids (fats)

Answer 19

broken down after carbs

Question 20

proteins

Answer 20

least likely to be broken down for energy

Question 21

autotrophs

Answer 21

make their own food / producers / get energy from NONLIVING sources

Question 22

photoautotroph

Answer 22

use sun

Question 23

chemoautotrophs

Answer 23

use chemicals

Question 24

heterotrophs

Answer 24

consumers / get energy from LIVING or ONCE LIVING organisms

Question 25

herbivore

Answer 25

eat plants only

Question 26

carnivore

Answer 26

eat animals only

Question 27

omnivore

Answer 27

eat plants and animals

Question 28

decomposer/detritivore

Answer 28

eat dead/decaying organisms

Question 29

rule of 10

Answer 29

as energy flows from organism to organism it is used for metabolism and converted to heat. then the next organism on the chain only receives 10% of the energy

Question 30

food webs

Answer 30

shows multiple food chains at once, and how they interconnect
