| Define Atoms | Make up Matter
🗑
|
||||
| Define Electron | Found outside nucleus, have negative charge
🗑
|
||||
| Define Proton | Found inside nucleus, have positive charge
🗑
|
||||
| Define Neutron | Found inside nucleus, have no charge
🗑
|
||||
| Define Element | Made up of one type of Atom
🗑
|
||||
| Define Molecule | Atoms of the same element bonded together
i.e) O2
🗑
|
||||
| Define Compound | Made up of two or more different elements that combine chemically
i.e) H20-water; CO2; CO
🗑
|
||||
| Define Mixture | Made of substances that combine physically
Can be solids, liquids or gases or combinations of both
i.e) sand and baking soda; chocolate chip ice cream
🗑
|
||||
| Explain the difference between inorganic and organic compounds | Organic) Contains carbon
Inorganic) Does not contain carbon
🗑
|
||||
| Explain the difference between a solution and a suspension | Solution) two or more substances are combined evenly
Suspensions) gas or liquid has another substance evenly spread throughout it
🗑
|
||||
| Explain why blood is a suspension | Blood cells can sink to the bottom without being "mixed" by circulation of blood flow.

| What are the three reasons water is important? | living things are made of more than 50% water
needed for chemical reactions to occur
used to transport materials throughout the organism
🗑
|
||||
| Define carbohydrates | supply energy for cell process
made up of sugar and starches-like glucose
🗑
|
||||
| What are the three characteristics of lipids? | fats and oils; do not mix with water
release a larger amount of energy than carbohydrates; harder to break down
found in cell membranes; make cell membrane selectively permeable b/c fats and oils do not mix with water
🗑
|
||||
| Since lipids have more energy stored in their bonds why does the body get more use-able energy from carbohydrates | your body converts them to glucose and your body runs on glucose

🗑
|
||||
| Define DNA and where it is located in the cell | deoxyribonucleic acid
nucleus
🗑
|
||||
| Define enzymes | regulate all chemical reactions in cell, can speed up the rate of a reaction
proteins
🗑
|
||||
| Explain why mitochondria are important | Break down cristae into energy
🗑
