Across
- 6. is the smallest component of an element that retains all of the chemical properties of that element.
- 8. a long chain of monosaccharides linked by covalent bonds.
- 10. readily absorb excess H+ or OH–, keeping the pH of the body carefully maintained in the aforementioned narrow range.
- 11. can form four covalent bonds to create an organic molecule.
- 12. positive ions are formed by losing electrons.
- 16. found in fruit.
- 17. a reaction in which the removal of a water molecule occurs.
- 18. reside in the nucleus of an atom.
- 19. is a negatively charged particle that travels in the space around the nucleus.
- 20. occupies space and has mass
Down
- 1. part of lactose, or milk sugar.
- 2. are simple sugars, the most common of which is glucose.
- 3. also called biological.
- 4. large molecules necessary for life that are built from smaller organic molecules.
- 5. are those substances that readily donate OH–.
- 7. Another type of strong chemical bond between two or more atoms.
- 9. are biomolecules with which most consumers are somewhat familiar.
- 13. are substances that provide hydrogen ions (H+) and lower pH, whereas bases provide hydroxide ions (OH–) and raise pH.
- 14. is the storage form of glucose in humans and other vertebrates, and is made up of monomers of glucose
- 15. is the stored form of sugars in plants and is made up of amylose and amylopectin.
