Organelles and protein
formation
SAP1. Students will analyze
anatomical structures in
relationship to their
physiological functions.
► d.
Relate cellular metabolism and transport
to homeostasis and cellular reproduction.
► e. Describe how structure and function are
related in terms of cell and tissue types.
Define in your own words.

Characteristics of Eukaryotes
► Human
somatic cells
are eukaryotic
► Contain
nuclei (except
for RBC’s)
► Contain
membrane
bound organelles
Nucleus
► “Control
Center” of cell
► Contains
genetic
information
► DNA
dictates proteins
which are made by
that cell
Ribosomes
► Location
of protein
synthesis
► receives
nucleus
► Many
message from
are located on
rough ER
Rough ER
► As
proteins are made,
they are sent into rER
► Channels
proteins
throughout the cell
Golgi body
► Receives
rough ER
► Packages
protein from
and prepares
protein to be sent out
of cell
Cytoplasm
► Gel-like
► Surrounds
organelles
► Anaerobic
and holds
respiration
occurs here
Mitochondria
► Double-membraned
► Site
of aerobic
respiration
► Takes
in glucose, and
produces ATP
Plasma membrane
► Phospholipid
bilayer
► Control
what enters
and leaves the cell
► Made
of phospholipids,
proteins, and
cholesterol
Creation of a protein
►
Cells create proteins to conduct the jobs they are
specialized for
►
Protein can be for use in the cell, or can be transported
out.
►
Message to create protein comes from outside
Message is received
► External
stimulus
triggers protein
production
► Usually
hormonal cue
► Message
is transferred
into cell and sent to
nucleus
In the nucleus
► Message
triggers
nucleus to set
groundwork for protein
production
► Message
is then sent
to ribosome for
production
Finally
► Ribosome
passes new
protein through rER
► Is
sent to golgi for
packaging
► Sent
out through cell
membrane into body
