Across
- 3. ________ structure, the 3D relationship of different polypeptide chains in a multisubunit protein complex (10)
- 4. Common structural motif in proteins in which different sections of the polypeptide chain run alongside each other and are joined together by hydrogen bonding between atoms of the polypeptide backbone (4,5)
- 9. ______ energy, extra energy that must be possessed by atoms or molecules in addition to their ground state to undergo a chemical reaction (10)
- 10. Loss of electrons from an atom as occurs with the addition of oxygen or when hydrogen is removed (9)
- 11. Reaction through which two molecules are linked together through OH groups with the removal of molecular water (12)
- 13. Literally “water loving” (11)
- 16. A region on the surface of a protein that can interact with another molecule through noncovalent bonding (7,4)
- 17. ______ structure the complex 3D form of a folded protein (8)
- 18. ___ ___ cycle found in aerobic organisms which oxidises acetyl groups derived from food molecules to CO2 and H2O. In eukaryotes this occurs in the mitochondria (6,4)
- 22. _______ structure, the amino acid sequence of a protein (7)
- 23. ___________ phosphorylation, a process in bacteria and mitochondria in which ATP formation is driven by the transfer of electrons from food molecules to molecular oxygen (9)
- 24. Molecule on which an enzyme acts (9)
- 26. Polysaccharide composed exclusively of glucose units used to store energy in animal cells. Especially abundant in liver and muscle (8)

- 2. Literally “water hating” (11)
- 5. State at which there is no net change in a system (11)
- 6. Ubiquitous metabolic pathway in the cytosol in which sugars are partially metabolised to produce ATP (10)
- 7. Organic molecule that is insoluble in water but tends to dissolve in nonpolar organic solvents (5)
- 8. Reaction Cleavage of a covalent bond with the addition of water (10)
- 12. Abbreviation of a three word term, series of electron carrier molecules along which electrons move from a higher to a lower energy level to a final acceptor molecule, with associated production of ATP (3)
- 14. Net drift of molecules in the direction of lower concentration due to random thermal motion (9)
- 15. ______ structure, regular folding patterns in a protein (9)
- 19. Common folding pattern in proteins where in which a linear sequence of amino acids folds into a right handed coil stabilised by internal hydrogen bonding between backbone atoms (5,5)
- 20. Energy storage lipids in cells that are composed of triacylglycerols (3)
