name and label the structures:
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
electron transport chain.
draw ATP label it
high energy bond with stored energy
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
enzymes can speed up both processes
NADH is what
what is it when nude
electron piggy bank in cellular respiration
carries electrons from a place to another
Where does it happen
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
what is net gain of glycolysis
draw all the phases in glycolysis
Phosporylation causes unstability and breaks into 2 equal halves
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
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
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
what is total net gain for krebs
grand total net gain for both steps
what is electron transport chain
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
24 ATP from Krebs NaDH
4 ATP from Fadh2
4 ATP from Glycolysis NADH
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
How many ATP does NADH from KREBS make
How many ATP does FADH2 make
How many ATP does NADH from glycolysis make
what is the role of oxygen in cell respiration
it grabs the electrons from the proton channels and becomes H20.
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
what is molecule that phophoryaltes ATP
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
what is the net gain of cellular respiration
2 NADH= 4ATP
8 NADH=24 ATP
uses 8 H20
f 12 H20
FOR 1 GLUCOSE MOLECULE:
The total net gain
f 36 ATP
