Across
- 2. a type of protein that speeds up a chemical reaction by lowering the activation energy needed.
- 4. a monosaccharide and monomer. Used during cellular respiration to generate ATP.
- 8. This group of molecules comes in two forms, one is single stranded and one is double stranded. Both are involved with genes and protein synthesis.
- 12. the monomer of proteins, are carried to the ribosome by tRNA.
- 13. A diverse groups of molecules that perform many fucntions within a cell such as being a part of the cell membrane and helping to form structures.
Down
- 1. main component of cell membranes, have a hydrophobic and hydrophilic region.
- 3. the monomer of DNA and RNA, made of three parts: phosphate group, sugar, and nitrogenous base.
- 5. these 'hold' elements together, they can be broken and reformed to make new molecules. When we break them energy is released, when we make them it uses energy.
- 6. stores genetic information in the nucleus of eukaryotic cells
- 7. carries the genetic code into the cytoplasm where it can be used to create polypeptides
- 9. Molecule that can be used as an energy source (glucose) as well as for forming structures (cellulose).
- 10. the six most common elements needed for life
- 11. These can help to insulate organisms, as long term energy storage, and form structures like membranes.
