cellular respitation Flashcards
name and label the structures:
cristae
intermembrane space
matrix
inner membrane
outer
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
what is equation of cellular respiration
6 O2 + C6H1206 = 6 CO2 + 6H20 +ATP
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.
what are three steps of cellular respiration
glycolysis
kreb’s cycle
electron transport chain.
draw ATP label it
high energy bond with stored energy
adenine=purine
ribose sugar
adenosine
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
what happens when a phosphate is removed
it becomes ADP
draw an illustration of this
ATP>ADP>ATP
enzymes can speed up both processes
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+
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
what is the net gain of cell respiration glycolyis
2ATP
2 NADH
2 pyruvate
2 H20
what is net gain of glycolysis
2 ATP
2NADH
2 Pyruvate
2 H20
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.
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.
- 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
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.
Describe the totala net gain for glycolysis
2 pyurcate
2 ATP
2 NADH
2 H20
what is total net gain for krebs
6CO2
8 NADH
2 ATP
2 FADH2
grand total net gain for both steps
Grand total
4 ATP
10 NADH
2 H20
6 C02
2 FADH2
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.
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
