Card preview (24)
where does it happen
occurs in mitochondrial matrix
is oxygen required in link reaction
yes
what is like the starting thing of link reaction
Pyruvate (3C) enters via transport protein
3 titles of the link reaction steps
decarboxylation dehydrogenation formation of acetyl CoA
what happens in the 1st step
decarboxylation pyruvate looses Co2
what happens in the 2nd step
dehydrogenation NAD reduced to NADH
what happens in the 3rd step
formation of acetyl CoA 2C acetate combines with co-enzyme A to form acetyl Co-A
role of acetyl CoA in link reaction
transfers acetyl group into krebs cycle allows acetate to enter a cycle it otherwise couldn’t join
which molecule is reduced
NAD
which molecule is oxidised
pyruvate
in which form is carbon lost when the molecule is converted from pyruvate to acetate
CO2
name of carbon removal
decarboxylation
what enzyme catalyses carbon removal
decarboxylase
what combines with acetate to form Acetyl CoA
Co-enzyme A
for each glucose mol how many times does the link reaction happen and why
2 achos 2 pyruvate mol like generated in glycolysis <3 link back
whats the main point of like doing the link reaction whats the MAIN final product
2C Acetyl CoA (x2)
how much pyruvate is used in link reaction
2
how many Acetyl CoA produced
2
how many reduced NAD produced
2
how many CO2 produced
2
how many ATP produced
0
where does the Acetyl CoA produced go to
goes to krebs
where does the Reduced NAD produced go to
goes to ETC
where does the CO2 produced go to
breathed out
