| 7285222616 | Trans Fatty Acid | -unsaturated unless turned into a solid, saturated fatty acid -Hydrogen opp carbon -bad, hardly naturally produced, straight configuration makes it easy for them to stack onto each other which makes it hard to break down | 35 | |

| 8158356436 | What is the main function of glucose in the cell? | cell respiration | 44 | |
| 8158361428 | What is the opposite of a catabolic reaction? | Anabolic Reaction | 45 | |
| 8158361429 | Explain how the molecular structure of water allows it to dissolve a substance such as table salt | Since the molecular structure of water is polar, it allows other hydrophilic molecules, like salt, to dissolve within it | 46 | |
| 8158365231 | When you sweat, water evaporates from the surface of your skin decreasing your body temperature as this process requires heat energy. Explain why we use water as a coolant rather than methane. | The heat capacity of water is much higher than methane, meaning that it is much harder to change 1 degree of water than it is methane. Water is much more constant, and will not change as quickly as methane would in reaction to your skin | 47 | |
| 8158368303 | Explain why saturated fatty acids are solid at room temperature | They're solid at room temperature due to the single bonds that give them a straight structure | 48 | |

| 8158416676 | Polar molecules are | hydrophilic | 50 | |
| 8158416678 | Nonpolar molecules are | hydrophobic | 51 | |
| 8158439319 | What is an example of a hydrogen bond? | The attraction between a hydrogen of one water molecule and the oxygen of another water molecule | 52 | |
| 8158457217 | How do water molecules bond? | Through hydrogen bonding | 53 | |
| 8158460528 | Amino Acid | ![]() | 54 | |
| 8158515967 | The components of a triglyceride are | 1 glycerol and 3 fatty acids | 55 | |
| 8158524470 | Composed of carbon, hydrogen and oxygen, this macromolecules main function is to store and release energy | carbohydrate | 56 | |
| 8158584190 | Describe the different levels of organization of proteins | 1. Primary: Amino acids that are held together by peptide bonds. The genes determine sequence 2. Secondary: Held together by hydrogen bonds. Hydrophilic/phobic determines whether the shape will be alpha-helix or beta pleated sheet. Genes determine primary sequence, primary determines secondary, secondary determines tertiary, etc 3. Tertiary: All proteins reach up to this stage. Happens when secondary folds in on itself to create a 3d structure. Held together by hydrogen, hydrophobic, ionic, and covalent bonds 4. Quaternary: Multiple tertiary structures held together. Not all proteins reach this stage. Held together by same bonds as tertiary stage. Ex: hemoglobin | 57 |
