Flashcards in cellular respitation Deck (30):
1

name and label the structures: 

 

cristae

intermembrane space

matrix

inner membrane 

outer 

2

how does the structure and function help mitochondria acheive goal of repirater 

inner membrane has folds called cristae

 

increase surface area

 

gives us more membrane and more place to do chemical reactions 

3

what is equation of cellular respiration 

6 O2 + C6H1206 = 6 CO2 + 6H20 +ATP 

4

what is the main purpose of cellular respiration 

to break down large glucose molelucules and oxygen to make ATP, an important energy currency of cell. 

5

what are three steps of cellular respiration 

glycolysis 

 

kreb's cycle 

 

electron transport chain. 

6

draw ATP label it 

 

high energy bond with stored energy

 

adenine=purine 

ribose sugar

adenosine 

7

why ATP is main source of usable chemical enegy in cell

because negative oxygens are so close due to covalent bonds

 

unstable so want to come apart 

 

 

8

what happens when a phosphate is removed 

it becomes ADP 

9

draw an illustration of this 

ATP>ADP>ATP

See full size image

 

enzymes can speed up both processes

10

NADH is what 

 

what is it when nude

electron piggy bank in cellular respiration 

 

e-/H+ shuttle 

 

carries electrons from a place to another 

 

NAD+>NADH

 

like NADPH

 

NAD

11

Where does it happen 

 

When 

 

What and Why 

just in cytoplasm 

 

when glucose and ATP and phosphates are in abundance

 

Just the preliminary step for breaking down glucose into two pyruvates. which will have more use in the Krebs Cycle 

12

what is the net gain of cell respiration glycolyis

2ATP

 

2 NADH 

 

2 pyruvate 

 

2 H20

13

what is net gain of glycolysis 

2 ATP 

2NADH

2 Pyruvate

2 H20

14

draw all the phases in glycolysis

Investment phase

 

GLUCOSE+2ATP

Phosporylation causes unstability and breaks into 2 equal halves


PAYOFF

2 more random phosphates come in, giving off some hydrogens and electrons thus making NADH

 

you have glucose halves with total of 4 phophates. 4 ATP come in. 2 H20 are expelled so the phophates are easy to remove. 

 

in end 2 naked pyruvates are made 

 

refer to the word docs. 

15

What is the krebs cycle 

 

where 

 

when 

a cycle in the matrix that uses the carbon molecules in the pyruvates to make NADH, FADH2 and CO2.  dlkvdcf

 

this can only occur when there are pyruvates created. 

16

 

  1. make a basic diagram

 

pyruvate (3 carbon ) chain 

 

coenzyme-A comes in, takes out one carbon and becomes acetyl Co-A with 2 carbons

 

to make acetyl Co-A, Make NADH and CO2

 

 

 

17

krebs cycle diagram make it

 

describe it 

Oxaloacetic is like RuBP. 4 carbon, always in the cycle

 

Acetyle CoA comes in with 2C's and oxaloactetate becomes 6 carbon.

 

NAD+ and NADH come in and form respectively, forming 1 CO2  molecule

 

5C02 chain now when NADH come in, form another CO2 molecule 

 

4 C chain now and forms ATP 

 

NAD+ and NADH come in and now form 

 

FAD+ and FADH2 come in and form 

 

all the electrons will go to electron transport chain. 

 

 

18

Describe the totala net gain for glycolysis

2 pyurcate 

 

2 ATP 

2 NADH

2 H20

19

what is total net gain for krebs 

6CO2 

8 NADH

2 ATP 

2 FADH2

 

20

grand total net gain for both steps

Grand total 

 

4 ATP 

10 NADH

2 H20

6 C02

2 FADH2

 

 

21

what is electron transport chain 

where 

when 

why 

a series of chemical reactions on inner membrane that use up the electron banks NADH and FADH2 produced so to make ATP. THis is where most of the ATP is produced. 

22

 what is the net gain of electron transport chain

12 H20 

 

24 ATP from Krebs NaDH

 

4 ATP from Fadh2

4 ATP from Glycolysis NADH


32 ATP

 

23

how many H+ does Nadh from krebs pass throgh 

 

How many H+ does FADH2 pass through 

 

How many H+ does NADH from glycolysis pass through 

6

24

How many ATP does NADH from KREBS make 

 

How many ATP does FADH2 make

 

How many ATP does NADH from glycolysis make 

3

 

2

25

what is the role of oxygen in cell respiration 

it grabs the electrons from the proton channels and becomes H20. 

26

exactly how water is made in relation to NADH and FADH2 and NADH

4 electrons are needed in the last proton channel to make 2 H20. 

 

8NADH make 16 electrons make 4 pairs of H20, so that is 8 H20

 

2 FADH2 make 4 electrons to make 1 pairs of H20 so that is 2 H20. 

 

2 NADH made 4 electrons to make 1 pair of H20 so that is 2 H20 

 

 

In total 12 H20

27

what is molecule that phophoryaltes ATP

ATP synthase 

28

Draw the whole process including numbers of piggybanks, electrons, hydrogens, ions, number of NADH from glycolysis and number of ATP produced from each bank. 

REFER to NESE
