Phospholipid bi-layer |
|
|
|
What are the 3 roles of membrane proteins? |
Recognition protein's, Channel proteins, Carrier proteins |
|
|
|
Intracellular Fluid (ICF) |
The majority of the fluid, found inside our cells |
|
|
|
Where is Extracellular Fluid (ECF) found and what are the two types? |
Outside your cells. Interstitial fluid & plasma |
|
|
|
What are the 4 main tissue types? |
Epithelial, Connective, Muscle, Nervous |
|
|
|
Name & give each function of the speciality Epithelial tissues |
Exchange epithelial- for gas exchange between cells Transport epithelial- transport or exchange of non gas molecules for high volume exchange Ciliated epithelial- whisk contaminated mucus away from organs Protective epithelial- protection Secretary epithelial- makes up all glands endocrine & exocrine |
|
|
|
What is the difference between exocrine and endocrine glands? |
Exocrine- secrete either into lumen of organ or out of the body Endocrine- secrete hormones into blood |

Where are glial cells found and what is their function? |
Nervous tissue. To take care of neurons |
|
|
|
Apoptosis |
Programmed cell death; "cell suicide" |
|
|
|
What causes Apoptosis? |
Cell malformation Cell malfunctioning Embryonic development Virus infects cells |
|
|

Where is ATP produced? |
Mitochondria |
|
|
|
____________ is used to make the majority of the ATP we use for daily life. |
Aerobic Respiration |
|
|
|
Why does the number of mitochondria in a cell vary between cell type & tissue type? |
Because it is based on metabolic need/ demand |
|
|
|
# of mitochondria in a single cell may change in your life time due to change in _______. |
Metabolic need/ demand eg: pregnancy, tumor, exercise |
|
|
|
What are cell junctions used for? |
Communication between neighboring cells |
|
|
|
Name the 3 types of cell junctions and list their function. |
Gap junctions- channels between cells for exchange of materials Tight junctions- create leak proof barriers to prevent paracellular movement Desmosomes- anchors cells firmly together |
Think of how the name correlates to it's specific job |
