link reaction and kerb cycle

where does the link reaction (and the krebs cycle) take place

in the mitochondria matrix

describe the link reaction

• pyruvate is decarboxylated and a molecule of carbon dioxide is released

• pyruvate is oxidised and dehydrogenated and the two hydrogen atoms are used to reduce NAD to reduced NAD

• a molecule of acetyl CoA is produced and enters the krebs cycle

how many acetyl CoA are created and where does it go

2 - krebs cycle

how many reduced NAD are created and where does it go

2 - ETC

how many carbon dioxide are created and where does it go

out of the cell into the blood plasma

describe the krebs cycle

• one molecule of acetyl CoA is combine with oxaloacetate and citrate is formed

• citrate is decarboxylated and a molecule of CO2 is released 1citrate is then oxidised and dehydrogenated to form alpha ketoglutarate and two hydrogen atoms are used to reduce a molecule of NAD to form reduced NAD

• alpha ketogluterate is decarboxylated and a molecule of CO2 is released and a molecule of ATP is created by substrate-level phosphorylation

• alpha ketogluterate is oxidised and dehydrogenated to form oxaloacetate and four hydrogen atoms are used to reduce two molecules of NAD to form reduced NAD -two hydrogen atoms are used to reduce a molecule of FAD into reduced FAD AND oxaloacetate is formed

for one glucose molecule how many ATP molecules are created and where does it go

2 - cytoplasm to provide phosphates and energy

for one glucose molecule how many reduced NAD are created and where does it go

6 - ETC

for one glucose molecule how many reduced FAD are created and where does it go

2 - ETC

for one glucose molecule how many molecules of CO2 are created

4 - out of the cell intro the blood plasms

what is dehydrogenation

the removal of hydrogen

what is phosphorylation

addition of phosphate

what is dephosphorylation

removal of phosphate

what is decarboxylation

removal of CO2

what is oxidation

the loss of electrons (hydrogen)

what is t reduction

the gain of electrons (hydrogen)
