BIOCHEMISTRY 301 - LECTURE with 100%
correct answers (graded A+)
CELL - answer - it is the smallest unit that is capable of performing
life functions
- the structural and functional unit of all living organisms
- the building blocks of life
PROKARYOTIC & EUKARYOTIC - answer two types of Cells
PROKARYOTIC - answer - do not have structures surrounded by
membranes
- few internal structures
- one-called organisms
- unicellular
EUKARYOTIC - answer - contain organelles surrounded by
membranes
- most living organisms
- multicellular organisms such as plants and animal cell
CELL MEMBRANE - answer it's also called Plasma Membrane
CELL MEMBRANE - answer - outer membrane of cell that controls
movement in and out of the cell
PLASMA MEMBRANE - answer - barriers between inside and outside
of cell
- receives chemical and mechanical signals
, - transmits signal between -intra- and -extra- cellular spaces
CELL JUNCTIONS - answer - connecting individual cell together into a
multicellular organism
GAP JUNCTION
DESMOSOME
TIGHT JUNCTION - answer 3 types of Cell Junctions
HYDROPHILIC - answer Head
HYDROPHOBIC - answer Tail
GAP JUNCTION - answer - when two cells are right next to each
other, their cell membranes may actually be touching
- there is a space
DESMOSOME - answer - they physically connect cells like the gap
junction, but no opening is created
- important to preventing any pulling part of those organs in our
body that so much tension
- ex. heart muscles
TIGHT JUNCTION - answer - happens when two membranes actually
bond into one
- form solid wall
- solid wall means it is impermeable to any substances
- or nothing could get through
PHOSPHOLIPID BILAYER - answer - group together
