Biology Unit 1
Across
- 2. A molecule attracted to water
- 3. Causes similar molecules to stick together
- 5. a biomolecule consisting of carbon, hydrogen and oxygen atoms
- 6. An element with the same chemical properties but a different number of neutrons
- 8. cell energy
- 10. a class of organic compounds that are fatty acids or their derivatives and are insoluble in water but soluble in organic solvents
- 13. the breakdown of complex molecules in living organisms to form simpler ones, together with the release of energy
- 15. occurs when molecules very similar to the substrate molecules bind to the active site and prevent binding of the actual substrate
- 17. Causes dissimilar molecules to stick together.
- 21. A unit of double-stranded nucleic acids consisting of two nucleobases bound to each other by hydrogen bonds
- 23. a substance present in living cells, especially DNA or RNA, whose molecules consist of many nucleotides linked in a long chain
- 25. the active site of an adjoining protein subunit
- 26. a class of natural or synthetic substances composed of very large molecules
- 27. a weak bond based on the attraction between opposite electric charges.
- 28. The thing dissolving another substance
- 29. the mutual sharing of one or more pairs of electrons between two atoms
- 30. linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound
Down
- 1. a type of enzyme inhibition characterized by an inhibitor binding to an allosteric site resulting in decreased efficacy of the enzyme
- 4. any chemical reaction in which a molecule of water breaks one or more chemical bonds
- 7. the surface on which an organism lives or the substance on which an enzyme can act
- 9. a class of nitrogenous organic compounds that have large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms
- 11. the creation of larger molecules from smaller monomers where a water molecule is released
- 12. a molecule of a class compound that reacts with other molecules to form polymers

- 16. a virus that infects and replicates within bacteria and archaea
- 18. the process where food and drink turn into energy
- 19. the specific process where exogenous genetic material is directly taken up and incorporated by a cell through its cell membrane
- 20. A molecule consisting of a nitrogen-containing base, a phosphate group, and a sugar
- 22. the synthesis of complex molecules in living organisms from simpler ones together with the storage of energy
- 24. The thing being dissolved
- 29. When a liquid moves against the force of gravity, going up a thin tube
