Module 1 Cells as the basis of life
inquiry question 1
organelles
eukaryotic cell
more complex
has a nucleus
contains DNA
have membrane-bound cells
prokaryotic cell
less complex
does not have nucleus
no membrane-bound organelles
fluid mosaic model of cell membrane
structure
made up of three groups
carbohydrates
attached to protein
glycoprotein
attached to lipid
glycolipid
lipids
phospholipid bilayer
cholesterol (animal cell
phytosterol (plant cell
proteins
variety of proteins
scattered and suspended in phospholipid bilayer
involved in the transport of larger molecules
function
separates cell from surroundings
semipermeable
movement of certain materials in and out of cells
keeps constant concentration of substances
inquiry question 2
enzymes
effects if the environment on activity
substrate concentration
temperaure
high temperatures may cause the enzyme to denature
low temperatures may stop function of enzymes, not denaturing
pH
different enzymes function best at different optimum pH's
structure
composed pf protein molecules
surface of enzyme within specific shape
called active site
accommodate for substrate
function
assist with the metabolic reaction in living cells
movement of materials
active
endocytosis
large particles moving into cell
cell membrane changes its shape, engulfing
exocytosis
substances are transported to the external environment of cell
passive
diffusion
net movement of any molecules from high region to low region of concentration
reaches equilibrium
state occurring when concentrations are the same (no net movement)
osmosis
type of diffusion
movement of water across semi-permeable membrane
movement of particles that do not require input of energy
volume ratio
smaller volume ratio
faster rate of diffusion
cell requirements
matter (gases, simple nutrients, ions)
carbohydrates
three classifications
monosaccharide
source of quick energy
disaccharides
contains two monosaccharides
polysaccharides'
stores energy in plant cells
lipids
energy stored in the cell
double the energy of carbohydrates
essential structural parts of hormones
proteins
form structural compounds in cells
nucleic acids
two types
DNA
RNA
light energy
chemical energy
remocal of wastes
biochemical processes
photosynthesis
word equation
carbon dioxide + water --> glucose + oxygen
chemical equation
6Co2 + 6H2O --> 6O2+ C6H12O6
process using light energy to break apart water
cellular respiration
word equation
glucose+ oxygen--> carbon dioxide + water (+energy ATP)
chemical equation
C6H12O6 + 6O +ADP + P --> 6CO2 + 6H2O +ATP
