1.2 respiration = a series of
chemical reactions that
release energy by breaking
down large food molecules
1.3 respiration happens
in every cell
1.4 the energy released by respiration is
used to power some of the chemical
reactions happening in cells, eg...
220.127.116.11 energy is needed to make muscles contract
1.4.2 ACTIVE TRANSPORT
18.104.22.168 active transport uses energy to
move substances in and out of cells
1.4.3 SYNTHESIS OF LARGE MOLECULES
22.214.171.124 lots of large molecules (polymers) are made
by joining a whole loada smaller molecules
together, which requires energy. For example...
126.96.36.199.1 GLUCOSE is
in plant cells.
188.8.131.52.2 in microorganisms and plant
and animal cells GLUCOSE
and NITROGEN are joined
together to make AMINO
ACIDS, which are
consequently joined together to
2 there are two types of respiration...
2.1.1 'aerobic' = 'with oxygen'
2.1.2 aerobic is
2.1.3 it releases MORE
2.1.4 takes place in animal
and plant cells, and in
2.1.5 Let's learn the word and symbol equations! Yeah! Fun!
2.2.1 'anaerobic' = 'without oxygen'
2.2.2 takes place in plant and animal cells
and some microorganisms when
there ain't enough oxygen, eg...
184.108.40.206 HUMAN CELLS
220.127.116.11.1 when one does vigorous
exercise (eg. twerking) your
body can't supply enough
oxygen for aerobic respiration so
cells are forced to COMMENCE
18.104.22.168 PLANT CELLS
22.214.171.124.1 if the soil a plant (eg. doughnut
tree) is growing in becomes
waterlogged there'll be no oxygen
available for the roots and it will
be forced to COMMENCE
126.96.36.199 BACTERIAL CELLS
188.8.131.52.1 bacteria can get under your (and my) skin
through puncture wounds from things like
nails, but there's very little oxygen under
your (or my) skin, so the bacteria will be
forced to COMMENCE ANAEROBIC
2.2.3 anaerobic respiration can produce stuff...
184.108.40.206 LACTIC ACID is
produced in animal
cells and some bacteria
220.127.116.11.1 the word equation
18.104.22.168.1.1 glucose --> lactic acid (+ energy released)
22.214.171.124 ETHANOL and CARBON DIOXIDE is produced in
plant cells and some microorganisms (eg. yeast)
126.96.36.199.1 the word
188.8.131.52.1.1 glucose --> ethanol + carbon dixide (+ energy released)
184.108.40.206.2 FERMENTATION = when microorganisms break down sugars
into other products pendant que ils respire anaerobically
220.127.116.11.2.1 humans use fermentation to make a whole
loada things (we're good like that), for example...
18.104.22.168.22.214.171.124 biogas = a fuel used for
heating, lighting, etc.
126.96.36.199.188.8.131.52 lots of different
used to make biogas
184.108.40.206.220.127.116.11.1 the microorganisms ferment plant and animal waste
containing carbohydrates, eg. sugars like glucose
18.104.22.168.22.214.171.124.1.1 the biogas that gets produced is mainly made of methane and carbon dioxide
126.96.36.199.188.8.131.52 made using yeast, which ferment the
carbohydrates in the flour and release carbon
dioxide, which causes the bread to rise..yay!
184.108.40.206.220.127.116.11 alcohol is formed when yeast ferment sugar
18.104.22.168.22.214.171.124 the sugar used in alcohol comes from things like
grapes (wine), barley (beer) and Ian (magma).
