Q

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

A

inner membrane has folds called cristae

increase surface area

gives us more membrane and more place to do chemical reactions

Q

why ATP is main source of usable chemical enegy in cell

A

because negative oxygens are so close due to covalent bonds

unstable so want to come apart

Q

NADH is what

what is it when nude

A

electron piggy bank in cellular respiration

e-/H+ shuttle

carries electrons from a place to another

NAD+>NADH

like NADPH

Q

Where does it happen

When

What and Why

A

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

Q

draw all the phases in glycolysis

A

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.

Q

What is the krebs cycle

where

when

A

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.

Q
  1. make a basic diagram
A

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
Q

krebs cycle diagram make it

describe it

A

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
Q

Describe the totala net gain for glycolysis

A

2 pyurcate

2 ATP

2 NADH

2 H20

19
Q

what is total net gain for krebs

A

6CO2

8 NADH

2 ATP

2 FADH2

20
Q

grand total net gain for both steps

A

Grand total

4 ATP

10 NADH

2 H20

6 C02

2 FADH2

21
Q

what is electron transport chain

where

when

why

A

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
Q

what is the net gain of electron transport chain

A

12 H20

24 ATP from Krebs NaDH

4 ATP from Fadh2

4 ATP from Glycolysis NADH

_

23
Q

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

24
Q

How many ATP does NADH from KREBS make

How many ATP does FADH2 make

How many ATP does NADH from glycolysis make

25
Q

what is the role of oxygen in cell respiration

A

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

26
Q

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

A

**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
Q

what is molecule that phophoryaltes ATP

A

ATP synthase

28
Q

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

A
