1What is the main job of the cell membrane?
- ATo control what enters and leaves the cell
- BTo provide protection, structure, and support for the cell
- CTo provide energy for the cell
- DTo convert solar energy into food
2The cell membrane is mostly made of [blank_start]phospholipids[blank_end].
- Aphospholipids
3The cell membrane [blank_start]semi-permeable[blank_end], which means it only allows certain things in and out.
- Asemi-permeable
4Another name for the cell membrane is the [blank_start]lipid bilayer[blank_end]
- Alipid bilayer
5What kind of molecules can pass through the outer layer of the cell membrane?
- ACO2
- BC6H12O6
- CH20
- DO2
- EC10H14
6Molecules that are too large to pass through the outer layer of the cell membrane pass through the [blank_start]protein channel[blank_end].
- Aprotein channel
7Because of its size, glucose would have to pass through the [blank_start]protein channel[blank_end].
- Aprotein channel
- Bouter/inner layer of the cell membrane
8[blank_start]Marker proteins[blank_end] are used to identify the cell.
- AMarker proteins
9Which of these are true about diffusion?
- ASubstances move from high to low concentration.
- BSubstances move from low to high concentration.
- CIt is one of the three types of passive transport.
- DIt is one of the general ways of transportation in the cell membrane
- ENo assistance is needed for diffusion.
- FOyxgen and carbon dioxide are examples of substances that enter/leave cells by diffusion.
10[blank_start]Equilibrium[blank_end] is when there is equal concentration throughout. When this occurs, there is an equal amount of substances leaving and entering the cell.
- AEquilibrium
11In [blank_start]osmosis[blank_end], water moves across a membrane, from high to low concentration.
- Aosmosis
12In osmosis, water moves toward an area of [blank_start]high[blank_end] concentration.
- Ahigh
- Blow
13In [blank_start]facilitated diffusion[blank_end], substances move from high to low concentration but through the protein channel.
- Afacilitated diffusion
14[blank_start]Glucose[blank_end] enters/leaves cells by facilitated diffusion.
- AGlucose
15[blank_start]Metabolism[blank_end] is the process of converting food into energy.
- AMetabolism
16In eukaryotic cells, most metabolism occurs in the [blank_start]mitochondria[blank_end].
- Amitochondria
17THe only form of energy any living cell can use is called [blank_start]ATP[blank_end].
- AATP
18[blank_start]Cellular respiration[blank_end] is the process that living things use to convert food into usable energy: ATP.
- ACellular respiration
19What molecules (reactants) are needed for cellular respiration to occur?
- AGlucose (C6H12O6)
- BOxygen (O2)
- CCarbon Dioxide (CO2)
- DWater (H2O)
- EATP
20[blank_start]Photosynthesis[blank_end] is the process in which solar energy is turned into food.
- APhotosynthesis
21What molecules (reactants) are needed for photosynthesis to occur?
- ACarbon dioxide (CO2)
- BWater (H20)
- CSolar energy
- DGlucose (C6H1206)

22What are the products created by cellular respiration?
- ACarbon Dioxide (CO2)
- BWater (H2O)
- CATP
- DGlucose (C6H1206)

23What are the products created by photosynthesis?
- AGlucose (C6H1206)
- BOxygen (O2)
- CCarbon dioxide (CO2)
- DWater (H2O)
24How is ATP produced?
- ADirectly from the food you eat
- BFrom ADP, a phosphate atom, and energy
- CWhen ADP is used and broken down
25ADP is produced when ATP is used/broken down.
- AVerdadero
