- Respiration
- Metabolic Processes
- Anabolism
- Catabolism
- Active Transport
- Secretion
- DNA replication
- Muscle Contraction
- Activation of Chemicals e.g. Glucose is phosphorylated in glycolysis
- ATP
- Phosphorylated Nucleotide
- Adenine
- Ribose Sugar
- Adenosine
- Adenosine mono-, di-, triphosphate
- Adenosine
- Ribose Sugar
- Can be hydrolysed to ADP + Pi
- Reversible Reaction
- Small manageable amounts of energy that won't harm the cell
- When work needs to be done inside a cell a Pi group can be broken off releasing energy
- Reversible Reaction
- Coenzymes
- NAD
- Hydrogen Acceptor
- Reduced NAD
- Hydrogen is donated to the electron transport chain
- Produced in...
- Glycolysis
- 2 molecules
- The Link Reaction
- 1 molecule per Pyruvate, 2 molecules per Glucose
- Krebs Cycle
- 3 molecules of NAD, 1 molecule of FAD per cycle, 6 molecules of NAD 2 molecule of FAD per Glucose
- Glycolysis
- Reduced NAD
- Hydrogen Acceptor
- CoA
- Carries acetyl molecules from the link reaction to the Krebs Cycle
- Can also carry fatty acids into the mitochondrial matrix where they are broken down into acetyl groups which can then enter the Krebs Cycle
- Carries acetyl molecules from the link reaction to the Krebs Cycle
- NAD
- The Metabolic Pathways of Respiration
- Glycolysis
- Glucose
- 1,6 - Bisphosphate
- Triose Phosphate
- Pyruvate
- Triose Phosphate
- 1,6 - Bisphosphate
- 2 molecules of ATP
- Substrate Level Phosphorylation
- 2 molecules of reduced NAD
- Dehdrogenase Enzymes
- Takes place in cell cytoplasm
- Glucose
- The Link Reaction
- Pyruvate is converted into Acetate
- Acetate combines with Co-enzyme A to form Acetyl Co-enzyme A complex
- ACoA complex is transported to the Krebs Cycle
- Acetate combines with Co-enzyme A to form Acetyl Co-enzyme A complex
- Decarboxylation
- DecarboxylaseEnzymes
- Occurs in Mitochondrial Matrix
- Dehdrogenation
- 1 molecule of reduced NAD per molecule of Pyruvate (2 per molecule of glucose)
- Dehydrogenase Enzymes
- No ATP is produced
- Reduced NAD is produced
- Pyruvate is converted into Acetate
- The Krebs Cycle
- ACoA dissociates and Acetyl enters the Krebs Cycle

- Glycolysis
- Mitochondria
- Inner and Outer Membrane
- Intermembrane Space
- Inner Membrane is folded into Cristae
- Large Surface Area for ATP Synthase Enzymes
- Stalked Particles
- ATP Synthase
- Matrix
- The Link Reaction & The Kreb's Cycle
- Inner and Outer Membrane
- Oxidative Phosphorylation
- Requires Hydrogen ATOMS from the previous metabolic pathways of Respiration
- Hydrogen atoms split to form protons and electrons
- Electrons are transported down the electron transport chain
- Oxygen acts as the final electron acceptor
- Electrons combine with protons to form Water
- Protons are in solution in the matrix
- Electrons combine with protons to form Water
- Oxygen acts as the final electron acceptor
- Protons go into solution in the matrix
- Electrons are transported down the electron transport chain
- Hydrogen atoms split to form protons and electrons
- Electron Transport Chain
- Electron Acceptor Proteins
- Movement of electrons provides energy for H+ ion to be pumped from the matrix into the intermembrane space
- Build up of protons in the intermembrane space
- Protons flow down ATP synthase enzymes
- Chemiosmosis
- Kinetic energy provides energy for the attachment of ADP and Pi to form ATP
- Protons flow down ATP synthase enzymes
- Build up of protons in the intermembrane space
