|
||||
| Which membrane type allows some things through and restricts the passage of others? | Selectively permeable
🗑
|
||||
| What are all body fluids that are located outside of cells called? | Extracellular fluid
🗑
|
||||
| Intracellular fluid | Intra means "within," so this is referring to fluid inside the cell membrane.
🗑
|

| Blood | Blood is an extracellular fluid, but it is located within the blood vessels.
🗑
|
||||
| What drives filtration through a membrane? | Physical pressure
🗑
|
||||
| Concentration gradients | Concentration gradients drive diffusion and osmosis, not filtration.
🗑
|

| The majority of the plasma membrane can be described as a bilayer of _____________ with associated proteins. | Phospholipids
🗑
|
||||
| The glycocalyx is Blank______ to the plasma membrane. | external
🗑
|
||||
| Movement of gas molecules (oxygen and carbon dioxide) between the air in the lungs and the blood or between the blood and the tissues is by which process? | Diffusion
🗑
|
||||
| The net flow of water from one side of a selectively permeable membrane to the other side is called | osmosis
🗑
|
||||
| Which are usually prevented from moving across the selectively permeable membrane of a cell? | Proteins
allows nutrients and wastes to go through but prevents other things like proteins and phosphates
🗑
|
||||
| In blood capillaries, blood pressure forces fluid through gaps in the capillary wall in a process called | filtration or capillary filtration
🗑
|
||||
| The fluidity of the plasma membrane is primarily provided by the Blank______. | phospholipids
🗑
|
||||
| Define tonicity | The ability of a solution to cause osmosis, affecting volume and pressure in the cell
🗑
|
||||
| Oxygen passes into the bloodstream across the membranes in the lung by the process of | Diffusion
🗑
|
||||
| What is the net flow of water down its concentration gradient through a selectively permeable membrane called? | osmosis
🗑
|
||||
| In carrier-mediated transport, one carrier can transport 1000 glucose molecules per Blank______ across the membrane | second
🗑
|
||||
| Which of the following moves large particles and fluid droplets across the cell membrane? | Vesicular transport
🗑
|
||||
| Vesicular transport that releases material from the inside of the cell to the outside of the cell is called | exocytosis
;exocytosis release material from the cell
🗑
|
||||
| endocytosis | vesicular processes that bring matter into the cell
🗑
|
||||
| The process in which a physical pressure forces fluid through a selectively permeable membrane is called | filtration
🗑
|
||||
| three types of protein structures that contribute to the cytoskeleton | Microtubules
Microfilaments
Intermediate filaments
🗑
|
||||
| The ability of a solution to affect the fluid volume and pressure in a cell is | tonicity
🗑
|
||||
| Example of a membranous organelle? | Nucleus, mitochondria, lysosomes, peroxisomes, endoplasmic reticulum and Golgi complex
🗑
|
||||
| What is the net movement of particles from a region of higher concentration to a region of lower concentration called? | simple diffusion or diffusion :)
🗑
|
||||
| Foreign bodies such as viruses, bacteria, or dust particles that have been phagocytized by the cell form types of Blank______ within the cytoplasm. | inclusions
🗑
|
||||
| In which process does a solute bind to a carrier in the plasma membrane that then changes shape and releases the solute to the other side of the membrane? | Carrier-mediated transport
🗑
|
||||
| Which are types of vesicular transport? | Endocytosis and exocytosis
🗑
|
||||
| The cytoskeleton is composed of calcium salts. T or F | False
The cytoskeleton is a system of microfilaments, intermediate filaments, and microtubules, that give the cell shape, allow movement, and the routing of molecules and organelles within the cell.

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
