|
What happens to electrons in Ionic Bonds? |
They get transferred. |
|
|
What happens to electrons in covalent bonds? |
Sharing- polar/unequal sharing and non-polar/equal sharing |
|
|
What are Hydrogen bonds? |
Weak bonds between hydrogen and negatively charged items. |
|
|
What does a pH scale determine and how is it determined? What is the scale range? |
Determines whether a substance is a base or acid and it is measured by the # of H ions Scale range is 0-14 |
|
|
What is the pH of blood and the stomach? |
Blood- 7.4 Stomach- 2 |
|
|
Name 6-7 properties of water |
Polarity, Cohesion, Adhesion, Low Density when Frozen, Versatile Solvent, High Heat of Fusion/Specific Heat, and Surface Tension |
|
|
Describe Adhesion |
Adhesion is when water molecules are attracted to other charged compounds |
|
|
Describe Cohesion |
Cohesion is when water molecules are attracted to other water molecules |
|
|
Explain why is density lowest when water is frozen |
Water's low density when frozen is caused by the spacing between hydrogen bonds and the crystalline structure within the ice. Explains why ice floats |
|
|
What is Capillary Action? |
When water is able to use cohesion and adhesion to move up a structure/surface ; used in plants |
|
|
What is the simplest form of organic molecule? |
Monomer |
|
|
How do monomers join together? Briefly explain this process. |
Monomers bind through dehydration synthesis. Dehydration synthesis is the loss of water and it is used to make polymers |
|
|
How are polymers broken down? Briefly explain. |
Hydrolysis breaks polymers down back into monomers. Hydrolysis uses the input of water. |
|
|
Explain how Carbohydrates are used by organisms |
They are used for energy in cellular respiration |
|
|
How is the carbohydrate, Glucose used? |
To make immediate energy and ATP |
|
|
How is the carbohydrate, Starch used? |
It is stored in plants |
|
|
How is the carbohydrate, Glycogen used? |
It is stored in animals (mainly the liver) |
|
|
How is the carb cellulose used |
by deez nutsPLANT CELL WALL :DDD sorry |
|
|
Fats, Waxes, Oils, and Sterols are... |
Lipids |
|
|
Compare and Contrast the properties of saturated and unsaturated fats. |
Saturated fats have a single bond, Unsaturated fats have at least one double bond. Both are lipids. |
|
|
List the monomers for Lipids, Proteins, Nucleic Acids, and Carbs |
lipids- fatty acids/ glycerol proteins- amino acids nucleic acids- nucleotides carbs- saccharides/ sugars |
|
