Cytoplasm

|---|---|---|---|---|---|
| Within cell plasma membrane: | cytoplasm
🗑
|
||||
| cytoplasm | everything between the plasma membrane and the nucleus (cytosol and organelles)
🗑
|
||||
| cytosol | intracellular fluid, 90% water and where lots of chemical reactions take place
🗑
|
||||
| organelles | specialized structures within the cell with specific shapes and functions.
🗑
|
||||
| cytoskeleton and 3 types (smallest to largest diameter) | network of protein filaments that extends throughout the cytosol. Microfilament, intermediate filaments, and microtubules.
🗑
|
||||
| Microfilament | Thin fibers of actin at edge of cell that support movement and give mechanical support (strength and shape of cells, support microvilli)
🗑
|
||||
| Microvilli | Have a core of parallel microfilaments. Greatly increase surface area, so abundant on cells involved in absorption, such as epthelial cells that line the small intestine.
🗑
|
||||
| Intermediate filament | Very strong (made of proteins). Found where subject to mechanical stress. Stabilize the position of organelles and nucleus. Help attach cells to one another.
🗑
|
||||
| Microtubule | Largest, made of long hollow unbranched tubes of protein (mainly tubulin). Help with shape of cell, movement of organelles (chromosomes during cell division), and movement of cilia and flagella.
🗑
|
||||
| cilia | numerous, short, hairlike, on cell surface, anchored by a basal body. oar-like movement. Moves fluids along a cell's surface. (lung and fallopian tube cells).
🗑
|
||||
| flagella | usually 1/cell. Whip-like (wave-like)motion that moves the entire cell. (Sperm tail).
🗑
|
||||
| ribosome | Make proteins. Little balls (containing lots of rRNA) mostly attached to rough ER. Made in nucleolus.
🗑
|
||||
| Endoplasmic reticulum | Extends from the nuclear envelope as flattened sacs or tubules. Rough ER secretes proteins. Smooth ER (extending off rough ER)detoxes (liver).
🗑
|
||||
| Organelle responsible for drug intolerances. | Smooth ER
🗑
|
||||
| Golgi Complex | "post office" Gets proteins from ribosomes of rough ER and packages and sorts and delivers them (out of cell, to membrane, or to organelles)
🗑
|
||||
| Lysosome (-lyso=dissolve) and processes | Dissolving vesicle containing digestive enzymes that can recycle worn-out organelles (autophagy) or engulf entire cell in which it resides (autolysis).
🗑
|
||||
| Proteasome | Very very small.Gets rid of nonfunctional/abnormal proteins.
🗑
|
||||
| Peroxisome | Smaller than lysosome. Gets rid of the H2O2 it produces during cellular metabolism. (very abundant in liver as they break down alcohol)
🗑
|
||||
| Mitochondria | "Powerhouse" making ATP by way of aerobic respiration reactions (lots in kidneys, heart, and liver). Contain there own DNA, from mother only since sperm head has few organelles. Cellular metabolism.
🗑

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.
