Bioenergetics
- Metabolism
- Metabolism is all the
reactions in your body
- Metabolic rate is how fast these reactions occur
- Examples
- Breakdown of excess proteins into urea
- Respiration
- Photosynthesis
- 1 molecule glycerol + 3
molecules fatty acid ->
lipid molecules
- Glucose + nitrate ions forming amino acids
- Breakdown of excess proteins into urea
- The more
muscular you
are, the higher
your metabolic
rate
- THE LIVER
- Detoxifies blood
- Turns glucose into
glycogen and
glycogen into
glucose
- Deamination of unwanted amino acids.
- Deamination is removing the amino group, then
the protein becomes ammonia which is toxic. It is
then turned into urea which is also toxic and
disolved into the blood stream. The kidneys then
filter it, turning urea into urine and it is stored in
the bladder until urination.

- Detoxifies blood
- AMINO ACIDS
- Made up of: Amino group, Rest of
the molecule and variable group.
- Amino acids are the
building blocks of protein,
they make up a large
proportion of our tissue.
- Made up of: Amino group, Rest of
the molecule and variable group.
- Metabolism is all the
reactions in your body
- Photosynthesis
- Carbon dioxide + Water -> Glucose + Oxygen
- 6CO2 + 6H2O -> C6H12O6 + 6O2
- 6CO2 + 6H2O -> C6H12O6 + 6O2
- Photosynthesis happens
in the chloroplasts in the
leaves
- Light intensity is
proportional to 1 over
distance squared
- Rate of photosynthesis affected
by light intensity (more light
intensity, higher rate of
photosynthesis. Eventually stops
as limited amount of chloroplasts
as plants don't need too much
energy.

- Glucose is
soluable ,
plants don't
want it to
osmose out
so they
store it as
starch
- Carbon dioxide + Water -> Glucose + Oxygen
- Aerobic respiration
- During exercise
- Heart rate increases
- Breathing rate increases
- Blood vessels
supplying to
muscles dilate
- Temp increases
- Heart rate increases
- Glucose + Oxygen -> Carbon dioxide + Water
- 6O2 + C6H12O6 -> 6CO2 + 6H20
- Exothermic reaction- releases energy
- 6O2 + C6H12O6 -> 6CO2 + 6H20
- Mitochondria
where most
aerobic
respiration
takes place
in cells
- These need
Glucose and
oxygen carried in
the blood stream
- These need
Glucose and
oxygen carried in
the blood stream
- Uses of Aerobic Respiration
- Building large molecules
from smaller ones
- mammals and birds
keep steady
temperatures
- Muscle contractions- movement
- Building large molecules
from smaller ones
- During exercise
- Anaerobic respiration
- Glucose -> Lactic Acid
- Body releases lactic acid instead of C20 + H2O
- Build up of Lactic acid
produces an oxygen debt
- Muscles become fatigued and stop contacting properly
- Oxygen debt must be repaid so we keep breathing heavily
even after exercising.
- Oxygen debt is the amount
of oxygen needed to react
with the accumulated lactic
acid and remove it from the
cells
- Blood flowing
through muscles
transports lactic
acid to liver
where it is turned
back into glucose
- Blood flowing

transports lactic
acid to liver
where it is turned
back into glucose
- Muscles become fatigued and stop contacting properly
- Build up of Lactic acid
produces an oxygen debt
- Body releases lactic acid instead of C20 + H2O
- Occurs when there's not enough
oxygen to react normally. Occurs in cytoplasm.
- Produces 1/19th of
the energy aerobic
respiration produces
- Uses
- When we exercise
- Yeast- breaks glucose into ethanol
- Fermentation:
- Fermentation:
- When we exercise
- Glucose -> Lactic Acid
- Homeostasis
- Controlling blood glucose levels
- Eating causes glucose levels to rise. causing crenation
- insulin secreting
cells stimulated
in pancreas
- insulin secreted
- insulin stimulates glucose uptake from blood
- Glucose levels fall
- Exercising causes glucose levels to fall
- pancreas stimulates glucagon
- glucagon stimulates liver
- liver releases glucose (it has
converted from glycogen)
- glucose levels rise
- glucose levels rise
- liver releases glucose (it has
converted from glycogen)
- glucagon stimulates liver
- Exercising causes glucose levels to fall
- Glucose levels fall
- insulin stimulates glucose uptake from blood
- insulin secreted
- insulin secreting
cells stimulated
in pancreas
- It's important to maintain glucose levels as if they're
too high water osmoses in and if they're too low
water osmoses out of cells, damaging them.
- Eating causes glucose levels to rise. causing crenation
- Controlling Temperature
- The body can control its temperature in a lot of different ways. Eg
- When the body is too hot
- Sweat glands release sweat which
evaporates, leaving the body cooler.
- Vasodilation- capillaries get wider and
this allows warm blood to flow nearer
the surface of the skin where heat can
be lost.
- Hairs on arms lie flat so they don't trap heat.
- Sweat glands release sweat which
evaporates, leaving the body cooler.
- When the body is too cold
- Tiny muscles cause hair on
our arms to stick up, they
then trap more warmth,
making us warmer.
- Vasoconstriction- capillaries constrict so
blood doesn't flow so near to the surface
and cannot lose heat as easily.
- Tiny muscles cause hair on
our arms to stick up, they
then trap more warmth,
making us warmer.
- When the body is too hot
- The body can control its temperature in a lot of different ways. Eg
- Controlling ion levels
- Kidneys responsible for regulating
mineral salts and ion
concentrations
- Kidneys responsible for regulating
mineral salts and ion
concentrations
- Controlling Water
levels
- Kidneys responsible for this, hypothalamus creates thirst.
- Kidneys responsible for this, hypothalamus creates thirst.
- Controlled by the hypothalamus
- Homeostasis is keeping a constant internal enviroment in the body.
- Controlling blood glucose levels
