- Respiration
- glucose + oxygen --> water + carbon dioxide
- Needed for contraction of muscles, mitosis etc..
- Glycolisis
- Glucose-6-phosphate
- By adding a phosphate to carbon 6 it creates a reaction: Phosphorylati-on reacyion
- Hexase - Bisphosphate
- Two molecules of ATP have been use due to it now having two phosphates
- Two triose phosphates
- Each contain three carbons
- Two pyruvates
- Two NAD is lost converting triose to pyruvate
- To get pyruvate an oxidation reaction occurs which removes two hydrogen atoms from the triose phosphates
- A net produce of two ATP is produced
- The next stage is The link reaction
- Takes place in the mitochondrion matrix
- Link reaction
- Occurs twice due to two pyruvaes
- Pyruvate is decarboxylated and dehydrogenated to produce an acetyl group
- Decarboxylation - removal of carboxyl group from a substrate molecule
- Dehydrogenation - Removal of hydrogen atoms from substrate
- Acetyl combines with CoEnzyme A
- Becomes Acetyl CoA
- Coenzyme NAD becomes reduced
- Coenzyme A accepts Acetyl CoA.
- This then goes to the Krebs cycle
- Krebs cycle
- Acetyl CoA
- Acetate
- Loss of Co2 from decarboxylation and dehydrogenation
- Mitochondrion matrix
- This is substrate level phosphorylation
- Acetyl CoA
- Krebs cycle
- This then goes to the Krebs cycle
- Coenzyme A accepts Acetyl CoA.
- Coenzyme NAD becomes reduced
- Becomes Acetyl CoA
- Decarboxylation - removal of carboxyl group from a substrate molecule
- Two ATP is lost during Hexase Bisphosphate
- The next stage is The link reaction
- Two NAD is lost converting triose to pyruvate
- Takes place in the cyctoplasm
- Glucose-6-phosphate
- Glycolisis
- Needed for contraction of muscles, mitosis etc..
- glucose + oxygen --> water + carbon dioxide
- Acetate
- Krebs cycle
