Topic 8 : Cell respiration and Photosynthesis AND OPTION C: Cells and Energy C1: Proteins
C.1.1: Secondary Structures Alpha Helix Beta Pleated Sheet
Prontosil is a competitive inhibitor that is used as an antibiotic because it inhibits folic acid synthesis in bacteria. Nerve gases like Sarin function by inactivating the enzyme ethanoyl (acetyl) cholinesterase.
C.3.1, 8.1.1:Oxidation/Reduction STATE: oxidation involves the gain of oxygen reduction involves the loss of oxygen
C.3.1, 8.1.1: Oxidation/Reduction STATE: oxidation involves loss of electrons reduction involves gain of electrons
C.3.1, 8.1.1:Oxidation/Reduction STATE: oxidation involves loosing hydrogen reduction involves gaining hydrogen
C.3.1, OiLRiG ???????( OiLRiG only applies to electrons and hydrogen)
(Aerobic)Cellular Respiration Formula GLUCOSE + OXYGEN + ADP +PiCARBON DIOXIDE + WATER + ATP C6H12O6 + 6O2 6CO2 + 6H2O
C.3.2, 8.1.2: Outline the process of glycolysis, including phosphorylation, lysis, oxidation and ATP formation
NAD: Electron CarrierNAD+ = oxidised form NADH + H + = reduced form NAD+ + 2H → NADH + H+
2 2 Oxidation of triose phosphate Reduction of NAD + to NADH + H + 2 2 Pyruvate Pyruvate
From one glucose molecule in glycolysis: 2 x ATP (net) 2 X (NADH + H+) 2 X pyruvate
NAD: Nicotinamide adenine dinucleotide, abbreviated NAD A co-enzyme is a non-proteinchemical compound that is loosely bound to a protein and is required for the protein's biological activity.
C.3.3, 8.1.3: Draw and label a diagram showing the structure of a mitochondria as seen in electron micrographs
