What is the size range of human neurine cells?
300–400 μm
How large are human sperm cells?
5 μm
What does the cell membrane separate from the cytosol?
Extracellular fluid
What does membrane asymmetry mean in living cells?
The two membrane layers have different compositions
Where are membrane carbohydrates located and what do they form?
On the outer face of the outer membrane layer, forming glycolipids and glycomolecules like blood type antigens.
What does the fluid mosaic model state about membrane lipids and proteins?
They are able to move laterally within the membrane.
What does the nucleus store as genetic material?
Deoxyribonucleic acid (DNA).
What is the cytoplasm compared to the cytosol?
Cytoplasm includes all cell materials except the nucleus; cytosol is the jelly-like fluid inside the cell.
What distinguishes smooth from rough endoplasmic reticulum surfaces?
Smooth ER lacks ribosomes; rough ER has ribosomes on its surface.
What is the role of the Golgi body in protein processing?
It matures, targets, and releases proteins from rough ER toward the cell membrane.
