Crossword CPA #8

Question 1

lack of this molecule will force you to use fermentation instead of cellular respiration

Answer 1

final electron acceptor

Question 2

step of cellular respiration; 2 pyruvic acids are converted into 2 identical molecules that can enter the krebs cycle; step has a net of zero ATPs but 2 co2 are released and 2 NADH are formed

Answer 2

synthesis of Acetyl-CoA

Answer 5

catabolic

Question 6

this happens to the electron acceptor in a redox reaction

Answer 6

reduced

Answer 7

metabolism

Question 8

suffix sometimes added to protein names to indicate thy are enzymes

Answer 8

-ase

Question 9

chemicals that increase the likelihood of a reaction but are not permanately changed in the process (ie enzymes)

Answer 9

catalysts

Question 10

step of cellular respiration; electron carriers drop off thier hydrogen ions and electrons here; results in 34 net ATP

Answer 10

electron transport chain

Answer 11

saturation

Question 12

light, water, and co2 are used to make glucose, o2, and ATP

Answer 12

photosynthesis

Question 13

this happens to the electron donor in a redox reaction

Answer 13

oxidized

Question 14

location in/on enzyme that interacts with a substrate

Answer 14

active site

Question 15

abbreviation for reactions in which a molecule loses an electron to another molecule

Answer 15

redox

Question 16

occurs when enzymes lose their 3D structure and no longer functional

Answer 16

denature

Question 17

type of inhibitor that binds somewhere other than an enzymes active site and causes the active site to change shape to prevent substrate binding

Answer 17

noncompetitive

Question 18

organism whose final electron acceptor during cellular respiration is o2

Answer 18

aerobic

Question 19

ie NAD+, NADP+, FAD+

Answer 19

electron carriers

process in which one glucose molecule can be broken down into 38 ATP

Answer 23

cellular respiration

Question 24

energy is stored in the bonds of this molecule

Answer 24
