Answer 11

6 carbon Citrate

Via combining with 4 carbon oxaloacetate

Answer 14

2, 2 & 2

Question 15

Where are the 5 enzymes located that are in the ETC

Answer 15

Inner mitochondrial membrane

Question 16

In ETC hydrogen ions also called

Answer 16

Protons

Question 17

In ETC protons are pumped via NADH & FADH2 where

Answer 17

Inter-membrane space

Increases the acidity and creates a gradient

Question 18

H+ ions will always move

Answer 18

Down their concentration gradient

Question 19

5th enzyme in ETC called

ATP synthase

Question 20

In ETC every NADH makes - ATP

Answer 20

3

Question 21

In ETC every FADH2 makes - ATP

Answer 21

2

Question 22

How many NADH in ETC = how many ATP

Answer 22

10 NADH = 30 ATP

Question 23

How many FADH2 in ETC = how many ATP

Answer 23

2 FADH2 = 4 ATP

Question 24

How is total of 38 ATP derived in glycolysis

Answer 24

10 NADH in ETC = 30
2 FADH2 in ETC = 4
2 ATP in Glycolysis 
2 ATP in Acetyl CoA formation
= 38 ATP

Question 25

What process replaces glycolysis in fat metabolism

Answer 25

Beta oxidation

Question 26

What is a phosphorylation reaction

Answer 26

An exchange of phosphate groups | Either gaining or losing

Question 27

Kinase always means a what

Answer 27

Phosphorylation reaction - so ATP or ADP is present somewhere

Question 28

What allows sugar into cells

Answer 28

Glucose 4 transporters

Question 29

How do you make citrate in citric acid cycle

Answer 29

Bind Acetyl CoA with oxaloacetate

Question 30

How does Krebs cycle affect no of carbons that make up molecules in it

Answer 30

Reduces the carbons from 6 (citrate)round to 4 (oxaloacetate) over and over - Acetyl CoA at beginning to start it all off again and make citrate

Question 31

8 molecules in Krebs cycle

Answer 31

``` Oxaloacetate Citrate Isocitrate Alpha-ketogluterate Succinyl CoA Succinate Fumerate Malate ``` Oxaloacetate

Question 32

How many turns of Krebs for 1 glucose molecule

Answer 32

Twice - 1 for each Acetyl CoA

Question 33

`where is FADH2 in krebs cycle

Answer 33

succinate>fumerate

Question 34

where are 3 NADH in krebs

Answer 34

isocitrate>ketoglutinate alpha-ketoglutinate> Succinyl coA Malate > oxaloacetate

Question 35

how many NADH made in krebs for each glucose molecule

Answer 35

6

Question 36

how many FADH2 made in krebs for each glucose molecule

Answer 36

2

Question 37

how many ATP made in krebs from each glucose molecule

Answer 37

2

Question 38

how many NADH made in krebs for each Acetyl CoA

Answer 38

3

Question 39

How many FADH2 in krebs for each Acetyl CoA

Answer 39

1

Question 40

How many ATP made in krebs for each Acetyl CoA

Answer 40

1

Question 41

which is the 5th and most important enzyme in ETC

Answer 41

ATP synthase

Question 42

what role to NADH and FADH play in ETC

Answer 42

electron donors

Question 43

what happens to NADH & FADH2 as they pass through ETC

Answer 43

get reduced - lose H+ ions

Question 44

where do the H+ ions go as they are released through the ETC

Answer 44

into inter-membrane space

Question 45

what happens in the inter0membrane space as ETC progresses

Answer 45

space becomes acidic and creates a gradient

Question 46
