Hey Everyone,
here's just a quick study guide for cellular respiration. I hope that
this will be somewhat helpful.

you gotta keep trying for EVER. it took me half an hour to get it to work, google pages is being rather shitty

it opens right up for me

Cellular Respiration Study Guide

 

1) Glycolysis (cytoplasm)

in – glucose

out – 2 pyruvate

 

-- provides enough energy for the immediate buildup of 2 ATP

--gain of 2 NADH

 

2) Preparatory Reaction (mitochondria)

in – 2 pyruvate

out – C2 acetyl group attached to CoA,   2 CO2

 

-- CO2 is given off

-- Reaction occurs twice per glucose molecule

 

3) Citric Acid/Krebs Cycle (matrix of mitochondria)

in – acetyl-CoA molecules

out – 4 CO2  per glucose molecule

 

-- 2 ATP per glucose molecule

 

4) Electron Transport Chain (cristae of the mitochondria)

in – 2 electrons for each NADH and FADH2 (which bring the electrons to the electron transport chain)

out – 3 ATP for each pair of electrons that entered by way of NADH, 2 ATP for each pair of electrons that entered by way of FADH2, O2 combines with H+ ions, forming H2O

 

-- 32 or 34 ATP

 

-----------------

Total number of ATP = 36 or 38

 

Organization of Cristae

-- within the cristae: electron transport chain

--The H+ flows through an ATP synthase complex from the intermembrane space into the matrix.

-- Chemiosmosis – how mitochondria produce ATP

-- ATP production is dependent upon the unequal distribution of H+ established by the pumping of H+ into the intermembrane space.

 

Fermentation

 

Def.: the metabolical recycling of NADH and producing NAD+ to continue glycolysis in the absence of oxygen

            -- lactic acid (humans)

            -- alcohol (e.g. yeast)

-- used, for example, during oxygen debt

-- produces 2 ATP (net)

 

Metabolism

 

-- all reactions in cellular respiration are a part of metabolism

-- substrates can be used for catabolism and anabolism

 

--catabolism: breaking down molecules

            e.g. proteins à amino acids

                  carbohydrates à glucose

                  fats à glycerol, fatty acids

--deamination: process that removes amino groups from amino acids (amino groups can’t be respired)

 

--anabolism: the building up of molecules

wow matt and helena.
youre my heros

thank you!

During fermentation, CO2 is also given off in yeasts.

If anyone cares.
