Across
- 1. – The electrode or terminal by which current leaves an electrolytic cell.
- 3. – An electrical circuit in which there is at least one place where current cannot flow
- 6. – A simple molecule sugar, such as glucose, fructose, or ribose, occurring naturally or obtained by the hydrolysis of glycosides or polysaccharides.
- 7. – Single-celled fungi commonly found on plants, on the skin, in intestines, and in soil and water. Yeast obtains energy through fermentation and are often used in the process of making bread.
- 11. – An electrical source and wires connected to a device.
- 12. – Produces electricity through a chemical reaction.
- 14. – A circuit that provides multiple paths for current to flow.
- 17. – The branch of chemistry concerned with the relationship between electrical energy and chemical change.
- 18. – Ethyl alcohol; derived by fermentation of plant materials; used as a fuel substitute/replacement for petroleum-based fuels.
- 19. – Simple sugar and building blocks for other nutrients.
- 21. – Process whereby a reactant gains one or more electrons
- 25. – The amount of energy required to increase the temperature of a one-gram sample of matter one degree Celsius.
- 26. – Enzyme that catalyzes cellulose.
- 27. – The electrode or terminal by which current enters an electrolytic cell.
- 28. – An electrical circuit in which current can flow.
- 31. – Material that has very little resistance and permits electrons to move through it easily.
- 33. – A material that has a very high resistance and resists the flow of electrons.
- 34. – A device used to stop the flow of electricity.
- 35. – A non-renewable energy source derived from originally living matter and typically extracted from below the Earth’s surface.
- 36. – An enzyme that catalyzes the hydrolysis of starch
- 37. – A chemical reaction through which organisms break down an energy-rich compound, typically sugars, without consuming oxygen and often resulting in the formation of alcohol; anaerobic respiration.
Down
- 2. – An extremely small, negatively charged subatomic particle found outside the atomic nucleus.
- 4. – A measure of electrical pressure.
- 5. – A complex sugar, starch. Comprised of three or more monosaccharides arranged in a chain.
- 8. – A unit of measure that represents the number of electrons passing a given point in one second.

- 20. – A circuit that provides a single path for current to flow.
- 22. – A device that offers specific resistance to current.
- 23. – An enzyme that catalyzes the breakdown of three-chain polysaccharides into monosaccharides.
- 24. – the causing or accelerating of a chemical change by the addition of a catalyst, such as an enzyme.
