- Cell Structure
- Total magnification
= magnification of
eyepiece/
magnification of
object
- magnification
of image = size
of image/ size
of object
- Highest
magnification with
light microscope -
x1500
- nucleus
- contains DNA
- controls
activities of the
cell
- contains DNA
- cell membrane
- has receptor molecules
- controls what
goes in and out
of the cell
- has receptor molecules
- millimeter = 10^-3m
micrometer = 10^-6m
nanometer = 10^-9m
- eukaryotic cells
have a nucleus
- plant cell
- animal cell
- plant cell
- prokaryotic cells
don't have a nucleus
- Bacteria
- Bacteria
- Transmission electron
microscope
- uses electron beam
instead of light rays
- x1 000 000
- uses electron beam
instead of light rays
- Scanning electron
microscope
- bounces electrons
off a surface with
an ultra thin
coating of heavy
metal
- only black and
white
- 3D
- bounces electrons
off a surface with
an ultra thin
coating of heavy
metal
- Total magnification
= magnification of

- What happens in cells
- DNA
- Double helix
structure
- polymer made up
of nucleotides
- Deoxyribose +
phosphate + base
- Deoxyribose +
phosphate + base
- Adenine - A
Thymine - T
Cytosine - C
Guanine - G
- A + T
C+G
- Double helix
structure
- Protein
- Genes have
the code for
protein
- Proteins made
from amino
acids
- DNA unzips
to act as a
template
for mRNA
- mRNA leaves
nucleus and
attaches to
ribosome
- carrier molecule
ferries in an amino acid
- Second one comes
startes protein
chain
- Second one comes
startes protein
chain
- carrier molecule
ferries in an amino acid
- mRNA leaves
nucleus and
attaches to
ribosome
- The sequence decides which
protein it is
- Genes have
the code for
protein
- Enzymes are biological catlysts
- large protein molecule
- active sites attach to
the substrate
- break down large molecule
- build larger
molecules
from smaller
ones
- change one
molecule into
another
- lock and key
- if the shape of the
active site changes
the enzyme is
denatured.
- pH
- Temperature
- substrate
concentration
- enzyme
concentration
- large protein molecule
- DNA
- Respiration
- Organisms need energy to
- drive chemical
reaction
- for
movement
- maintain
body
temperature
- cell division
- active transport
- transmit nerve
impulses
- drive chemical
reaction
- exothermic
- adenosine
triphosphate -
ATP
- energy
- 38
- 2
- energy
- anaerobic
used in
fermention
- glucose + oxygen
= carbon dioxide
+ water
- glucose =
ethanol + carbon
dioxide
- glucose = lactic acid
- carbohydrases
- amylase
- mouth, small intestine
- amylase
- protease
- stomach
- pancreas
- stomach
- lipase
- small intestine
- small intestine
- Organisms need energy to
- Photosynthesis
- Scientists
- 1660 Jan Baptist
van Helmont
- mass increase
wasn't just
minerals
- mass increase
wasn't just
minerals
- 1771 Joseph Priestly
- plants release oxygen
- plants release oxygen
- 1660 Jan Baptist
van Helmont
- carbon dioxide
+ water =
glucose +
oxygen
- endothermic
- light + chlorophyll
- carbon dioxide and
oxygen diffuse through
leaves
- the thing that
makes the graph
turn flat is called
the limiting factor
- Things that can
change the rate of
photosynthesis
- light intensity
- water levels
- carbon
dioxide
concentration
- temperature
- light intensity
- Scientists
