Q

First step:

Pyruvate broken down

A

Pyruvate molecule is split into two carbon molecules
A molecule of carbon dioxide which is given off as a waste product
High-energy electrons are transformed from the two carbon molecule to NAD+, Forming a molecule of NADH
The NADH moves to the electron transport chain

Q

Step two

Coenzyme A

A

Molecule called coenzyme a bonds to the 2 carbon molecule made from the breakdown of Pyruvate
This intermediate molecule goes to the Krebs cycle

Q

Step three citric acid form

A

The two carbon part of the intermediate molecule is added to a 4- carbon molecule to form a 6-carbon molecule called citric acid
CoA goes back to step two

Q

Step four citric acid broken down

A

Citric acid molecule is broken down by an enzyme and a five carbon molecule is formed
In molecule of NADH is made and moves out of the Krebs cycle
A molecule of CO2 is given off as a waste product

Q

Step 5 5 carbon molecule broken down

A

The five Carbon molecule is broken down by an enzyme
A 4 carbon molecule to molecule of NADH and a molecule of ATP are formed
The NADH leaves the Krebs cycle to CO2 is given off as a waste product

Q

Step 6 4 carbon molecule rearranged

A

And the same is rearranged the floor carbon molecule
High-energy electrons are released
Molecules of NADH and FADA H2 which is another electron Carrier are made
They leave the Krebs cycle and the four carbon molecules remain

Q

Step one of the electron transport chain

Electrons removed

A

Proteins inside the inner membrane of the mitochondria and take high-energy electrons from NADH and FADA H2.. Two molecules of NADH and one molecule of FADA H2 are used to.

Q

Step two hydrogen ions transported - electron transport

A

High-energy electrons travel through the proteins in the electron transport chain. The proteins use energy from the electrons to pump hydrogen ions across the inner membrane to produce a chemosmotic gradient, just as in photosynthesis. The hydrogen ions build up on the inside of the inner mitochondrial membrane

Q

Step three ATP produced - electron transport

A

Flow of hydrogen ions is used to make ATP. Hydrogen ions diffuse do a protein channel in the inner membrane of the mitochondria own. Channel is part of the ATP synthase enzyme. ATP synthase phosphate groups. ( ATP = between 36 and 38

Q

Step four water formed - electron transport

A

Oxygen fully enters the cellular respiration process. Oxygen pick up electrons and hydrogen ions to form water. Water molecules are given off as waste

Q

Where does cellular respiration occur

A

Mitochondria

17
Q

Can bacteria make respiration

A

Yes

18
Q

Do you need mitochondria to do respiration

A

No you cannot actually use their outer membranes to do in aerobic respiration

19
Q

What is aerobic respiration

A

Respiration in the presence of oxygen

20
Q

Respiration is for heterotrophs or autotroph’s?

A

Heterotrophs

21
Q

When you take organic compounds in the presence of oxygen you’re converting what and what

A

Carbon dioxide and water

22
Q

What do I do autotrophs do

A

Convert carbon dioxide and water back into organic material

23
Q

When is ATP

A

Little fuel that we use in all of our cell

24
Q

What are Cristaes

A

Folds

25
Q

When is the space in the middle of the mitochondria

A

Inner membrane space

26
Q

Glycolysis is where

A

Mitochondria specifically in cytoplasm of a cell or outside of bacteria

27
Q

In glycolysis what do you do

A

You take glucose (six carbon) break that down into two molecules of pyruvate
Pyruvate; three carbon inside it

28
Q

In glycolysis what do you generate

A

ATP and NADH

29
Q

Inlet call us if you also do you want

A

Transferring high-energy electrons to NADH and were adding protons
Pyruvate diffuses into the mitochondria
Pyruvate dehydrogenase complex; converts that three carbon molecules into acytl CoA A K a coenzyme a
Give off carbon in CO2 form

30
Q

Where is the matrix

A

Inside the mitochondria

31
Q

Kreb cycle produce what

A

Produce ATP, also adding energy to NADH and FADA H2

32
Q

In the electron transfer chain electrons…

A

Electrons move through a series of proteins in the energy of those proteins is used to pump protons

33
Q

Protons are hydrogen ions where

A

To the outside of the inner membrane into inner membrane space

34
Q

Look comes are going to be added to what

A

Other protons and oxygen that we read in in going to make water

35
Q

Protons flow through protein called

A

ATP synthase

36
Q

Protons combined with electrons and…

A

Oxygen in it’s going to make water can make 32 or 34 ATP

37
Q

Where does Lactaid acid fermentation take place

A

In muscles

38
Q

Cells do what in Lactic acid fermentation

A

Cells take glucose in glycolysis and breaking down into two pyruvate molecules
They convert pyruvate into lacte or lacte acid Subselect run so we can make NAD plus in can be recycled again breaking down lacte requires oxygen

39
Q

Alcoholic for me soon

A

Breaks into two pyruvate and then break into chemical called ethyl alcohol except electrons so NADP plus can be recycled again O2 is present

40
Q

BALANCED EQUATION

A

C6H12O6 + 6 O2 -> 6CO2 + 6H2O + ATP
