The energy needed to start a chemical reaction is
called activation energy.
 Even in a chemical reaction that releases energy,
activation energy must be supplied before the
reaction can occur.
 Enzymes are substances that increase the speed
of chemical reactions.


Temperature and pH value can alter an enzymes
effectiveness.
The enzymes that are active at any one time in a cell
determine what happens in that cell.
An enzyme’s shape determines its activity. Typically,
an enzyme is a large protein with one or more deep
folds on its surface. These folds form pockets called
active sites.
Enzyme inhibitors: are molecules that interact in
some way with the enzyme to prevent it from working
in the normal manner.
Non-specific methods of inhibition include any
physical or chemical changes which ultimately
denatures the protein portion of the enzyme and are
therefore irreversible.
COMPARE HETEROTROPHY AND AUTOTROPHY AND
THE ROLES OF THESE PROCESSES
IN THE ENVIRONMENT
 Temperature and pH value can alter an enzymes Directly or
indirectly, almost all of the energy in living systems needed for
metabolism comes from the sun.
 Metabolism involves either using energy to build molecules or
breaking down molecules in which energy is stored.
 Photosynthesis is the process by which light energy is converted to
chemical energy.
 Organisms that use energy from sunlight or from chemical bonds in
inorganic substances to make organic compounds are called
autotrophs.
 The chemical energy in organic compounds can be transferred to
other organic compounds or to organisms that consume food.
 Organisms that must get energy from food instead of directly from
sunlight or inorganic substances are called Heterotrophs.
 Cellular respiration is a metabolic process similar to burning fuel.
COMPARE CHEMOSYNTHETIC AND PHOTOSYNTHETIC
PROCESSES AND THE ROLES OF ORGANISMS USING
THESE PROCESSES IN THE ECOSYSTEM
 Ecosystems depend upon the ability of
some organisms to convert inorganic
compounds into food that other
organisms can then exploit.
 In most cases, primary food
production occurs in a process called
photosynthesis, which is powered by
sunlight.
 In a few environments, primary
production happens though a process
called chemosynthesis, which runs on
chemical energy. Together,
photosynthesis and chemosynthesis
fuel all life on Earth.
 The diagram below compares
examples of these two processes chemosynthesis in a seafloor
hydrothermal vent bacterium, and
photosynthesis in a terrestrial plant.

small amount of ATP and NADH.
Stage 2 When oxygen is present, pyruvate and NADH
are used to make a large amount of ATP. When oxygen
is not present, pyruvate is converted to either lactate
or ethanol and carbon dioxide.

Glycolysis
In the first stage of cellular
respiration, glucose is broken down
in the cytoplasm during a process
called glycolysis.
As glucose is broken down, some of
its hydrogen atoms are transferred
to an electron acceptor called
NAD+. This forms an electron
carrier called NADH.

Krebs Cycle
Acetyl-CoA enters a series of enzyme-assisted reactions
called the Krebs cycle, which follows five steps:
 Step 1 Acetyl-CoA combines with a four-carbon compound,
forming a six-carbon compound and releasing coenzyme A.
 Step 2 Carbon dioxide is released from the six-carbon
compound, forming a five-carbon compound. Electrons are
transferred to NAD+, making a molecule of NADH.
 Step 3 Carbon dioxide is released from the compound. A
molecule of ATP and a molecule of NADH are made.
 Step 4 The existing four-carbon compound is converted to a
new four-carbon compound. Electrons are transferred to an
electron acceptor called FAD, making a molecule of FADH2,
another type of electron carrier.
 Step 5 The new four-carbon compound is then converted to the
four-carbon compound that began the cycle. Another molecule
of NADH is produced.

Melanocytes are pigment-producing cells in the stratum basale, the deepest
layer of skin tissue.
Everyone has about the same number of melanocytes; what causes variations
in skin color is the amount of melanin, or pigment, these cells produce and how
spread out the pigment is from the center of the cell.
Also, in darker-skinned people, the melanin breaks down more slowly, and is
seen in all the layers of the skin, whereas in fair-skinned people, it breaks
down quickly and is rarely seen above the stratum basale.

In multicellular organisms like us, cellto-cell communication is of prime
importance for proper development and
function of the organisms as a whole.
Cells communicate with each other by
different means.
Adjacent cells can communicate via cell
surface molecules or via specific
junctions that allow the exchange of
solutes or the propagation of changes in
membrane potential.
Cells that are not in direct contact with
each other may communicate via soluble
messenger molecules.
Once released, a messenger molecule
acts on other cells that are responsive to
it (target cells).
In general, responsiveness requires the
presence of specific receptors for the
messenger molecule at the target cell.

ny person (or animal) that develops an autoAimmune disease, discovers that a certain
part of his body, or many parts, become
inflamed and painful. What is happening is
that the cells of the Immune System are
attacking those cells of the body that the
Immune System considers “foreign.”
Normally, the cells of the Immune System
recognize all the cells of the body and do not
consider them “foreign cells.” Normally, no
cells of the body are attacked by the Immune
System. The Immune System is “trained” by a
gland called the Thymus Gland to recognize
all the cells of its own body. This “training” is
still not completely understood.
However, the cells of the Immune System
normally recognizes the body’s cells and only
attacks “foreign” cells.
This extremely delicate situation is changed in
people with “Auto-Immune” diseases, and the
Immune System attacks specific cells of the
body, thereby creating over 80 different
diseases.

Transplant rejection is a process in
which a transplant recipient's immune
system attacks the transplanted organ
or tissue.
These harmful substances have proteins
called antigens on their surfaces. As
soon as these antigens enter the body,
the immune system recognizes them as
foreign and attacks them.
In the same way, an organ that is not
matched can trigger a blood transfusion
reaction or transplant rejection. To help
prevent this reaction, doctors "type"
both the organ donor and the person
who is receiving the organ. The more
similar the antigens are between the
donor and recipient, the less likely that
the organ will be rejected.

Most antigens expressed by human
cancer cells and recognized by host
T cells and antibodies are
nonmutated self antigens —
molecules also expressed on the
surface of normal cells.
These self antigens are ineffective
at triggering immune responses
against cancer cells, which provides
one explanation for the difficulties
in trying to immunize against
human cancer.
A new study describes how tumors
can avoid recognition by the
immune system and how
enhancing the affinity of the
interaction between a self antigen
and the MHC-I molecule may lead
to cancer immunity.

Antigens are defined as substances recognized

Factors determining whether an antigen will
stimulate an antibody response:





Degree of foreignness. Only human blood is
transfused to humans.
Size and complexity. Although red cells are
smaller than white blood cells, they tend to
be more antigenic due to the complexity of
the antigens on the cell surface. Some are
proteins and others are oligosaccharides.
Dose of antigen administered. How much
antigen is the individual exposed to and
what is the frequency of that exposure.
Genetic makeup of host may also dictate
whether an antibody is produced. Some
individuals have a greater ability to make
antibody and others have the antigen so they
would not make the antibody.
Antibody: Proteins produced by lymphocytes
as a result of stimulation by an antigen which
can then interact specifically with that
particular antigen.

Active Immunity - Vaccines are
used for health purposes to expose
our bodies to a particular antigen.
These antigens are usually killed
or severely weakened to decrease
their potency. After destroying
these pathogens, the body stores
some T cells as memory cells, due
to the fact they code for a
particular antigen and can be when
needed. This memory in T cells can
be a means of artificially acquiring
immunity while a genuine attack
by a pathogen is a naturally
acquired type of immunity.
Passive Immunity - This is where
immunity to particular antigens as
a result of genetic traits passed on
from parents rendering the
offspring immune to a particular
pathogenic threat.

proteins that directly perform
mitosis, G1, DNA replication, or

Brakes that can stop the cycle at
specific checkpoints (a.k.a
restriction points) regulate the
control system.
At checkpoints, feedback signals
conveying information about the
effector processes, or extracellular
signals, can delay progress of the
control system itself, so as to
prevent it from triggering the next
effector process before the previous
one is finished.
The two major checkpoints occur at
