Question 22

___ is the spot for cellular respiration

Answer 22

mitochindria, EXCEPT GLYCOLYSIS

Question 23

Steps and placement

Answer 23

Glycolysis outside, krebs/ citric acid cyle inside, ETC inside

Question 24

Subtrate level phosphoration

Answer 24

enzyme takes a phosphorus from a diff compound, turns ADP –> ATP

Question 25

NAD+

Answer 25

Nicotinamide adenine dinucleoid ( Niacin)

Question 26

NAD+ is a

Answer 26

coenzyme electron ACCEPTOR

Question 27

NAD+ accepts_____ w help from

Answer 27

2E’s + 2H help from ( dehydrogenase)

Question 28

NAD+ is now reduced to _____

Answer 28

NADH

Question 29

NADH is a electron

Answer 29

CARRIER

Question 30

NAD+ vs NADH

Answer 30

acceptor vs carrier

Question 31

NADH carries

Answer 31

2E’s and 1H

Question 32

from NADH, electrons transported via _____ , on _____ of ________

Answer 32

ETC, CRISTAE, Mitochondria

Question 33

_3__ views of ETC :

Answer 33

1) cool burn process 2) each lebel can be named / identified 3) oxidative phosphorlation

Question 34

cool burn process explained

Answer 34

AS E goes down, it loses more and more energy because the electronegativity increases. Oxygen waits at the bottom as it is extremely electronegative. The energy that is slowly lost is used for ATP

Question 35

2nd View explained

Answer 35

each level can be named/identified such as Q, Co Q10, and Ubiquinane.

Question 36

Supplement Q10

Answer 36

Assists ETC for E to be passed down

Question 37

What goes to the bottom?

Answer 37

2H ( 2 electrons are stripped) plus oxy at bottom

Question 38

3rd View; Oxidative Phosphorylation

Answer 38

ATP regenrated from ADP

Question 39

3RD View explained

Answer 39

1) NADH and FADH2 ( electron carries), deliver their electrons to ETC

2) Energy is released as electrons fall down.

3) ETC is used to pump H+ ions from matrix to intermembrance space

4) As H+ conc builds, they DIFFUSE back the inner membrane by the way of ATP Synthase

5)ADP is phosporlzed to ATP

Question 40

ATP synthase is needed to help H+ ions diffuse over because

Answer 40

inner is hydrphobic
