- Respiration -Key Words
- ATP
- A way of transferring energy from compounds such as glucose to cellular reactions where energy is needed
- Carboxylation reaction
- Addition of CO2 to a substance
- De-carboxylation reaction
- The removal of CO2 from a substance
- Dehydrogenation reaction
- Removal of hydrogen
- Redox
- Reduction and Oxidation
- Reduction
- Addition of electrons to a substance (addition of hydrogen /removal of oxygen)
- Oxidation
- Removal of electrons from a substance. Removal of electroons is usually brought about by the addition of oxygen/removal of hydrogen
- Co-enzyme
- Complex non-protein organic molecules functions as a carrier transferring chemical group as atoms from the active site of one enzymes in order to function E.g. NAD, FAD
- Electron
- Neg. charged subatomic particle - electrons orbit the nucleus and are responsible for most chemical processes
- Proton
- Postivie charged sub-atomic particle
- Chemiosmosis
- Theory on structure of ATP - proposes that the energy for the ATP-sysnthesis originates from the electrogradient of protons across membrane
- Substrate-Level Phosphorylation
- type of metabolic reaction that results in the formation of ATP by the direct transfer and donation of a phosphoryl group to ADP from a phosphorylated reactive intermediate.
- Occurs on the membrane of the chloroplast during photosynthesis
- Link Reaction
- Links glycolysis to the Kreb's cycle. Pyruvate molecules are oxidated and converted to Acetly Co A
- Krebs Cycle
- The sequence of reactions by which most living cells generate energy during the process of aerobic respiration; takes place in the mitochondria, using up O2, picking up CO2. ADP is converted into ATP.
- Oxidative Phosphorylation
- Occurs on the membrane of the mitocondria produces ATP
- Photophosphorylation
- Occurs on the membrane of the chloroplast during photosynthesis
- ATP
