BISC 101 EXAM REVISION QUESTIONS WITH
COMPLETE SOLUTIONS.
Nucleus
Contains DNA which is needed for cell function/memory
Nucelolus
Where ribosomes are made
ER
Proteins being made and trafficked to the Golgi lipids are made in smooth ER
Golgi
Further trafficking of proteins usually transports them out of the cell
Ribosomes
Machine that makes proteins
Cytoskeleton
Maintains structure and acts as a highway
Mitochondria
Powerhouse of the cell generates ATP
Cell Membrane
Protects cell and separates inside from outside
Macromolecules
, carbohydrates, lipids, proteins, nucleic acids
Proteins
Polypeptides are an example of this also amino acids combine to form proteins
Nucleic Acids
Nucleotides so like adosine thymine guanine and cytocysene and uracil
Carbohydrates
the starches and sugars present in foods
Lipids
fats and oils phospholipids lipids hate water
amphipathic
having both a hydrophilic region and a hydrophobic region aka phospholipids
The bilayer is
Hydrophobic in the middle and hydrophilic on on both surfaces
facillitated diffusion
Molecules move down along the concentration gradient
active transport
Energy-requiring process that moves material across a cell membrane against a concentration
difference
Bulk transport
