Respiration-The link reaction 0.0 / 5 ? BiologyRespirationA2/A-levelOCR Created by: TaraCBeckworthCreated on: 16-12-16 13:31 What is mitochondria? A cellular organelle where respiration occurs 1 of 10 Outer mitochondrial membrane Separates the organelle contents from the rest of the cell creating a cellular compartment perfect for aerobic respiration 2 of 10 Inter membrane space Proteins are pumped into this space by electron transport chains so a concentration gradient can be built up 3 of 10 Inner mitochondrial membrane Contains the electron transport chains and ATP synthase 4 of 10 Matrix Contains the enzymes for the link reaction and the krebs cycle and also the mitochondrial DNA 5 of 10 Cristae Projections of the inner membrane increasing the SA for the link reaction 6 of 10 What is the "true" name for the link reaction? Oxidative Decarboxylation 7 of 10 What is the first step in the link reaction? The pyruvate enters the mitochondrial matrix via active transport 8 of 10 Explain the oxidative carboxylation step The pyruvate's carbon is removed (decarboxylation) and the hydrogens are removed and accepted by NAD (oxidation) producing reduced NAD 9 of 10 What happens after oxidative carboxylation to prepare for the kreb cycle? 2-carbon acetyl is produced and bound with coenzyme-A to produce Acetyl CoA (this delivers the acetyl to the kreb cycle) 10 of 10
