Transcript Photosynthesis/Cell Respiration Review

CELL RESPIRATION AND
PHOTOSYNTHESIS
CELL RESPIRATION
O2 + C6H12O6  CO2 + H2O +(ENERGY)
Yeast
With and
without O2
Cell respiration
CO2 comes from ___________, we know this because
when the _____ was cut off, the yeast still produced CO2
Yeast with
multiple types
of sugars
Yeast was able to breakdown and metabolize simple
sugars and use that energy quicker.
*simple sugars give you a sugar rush, then you crash
when they are used up, Complex chains will last long
Monosacchari
de
Vs.
Disaccharide
Mono – single sugar molecule
Di – 2 single sugars linked together (linked through
dehydration synthesis)
PHOTOSYNTHESIS
CO2 + H2O + (LIGHT)  C6H12O6 + O2
Spinach leaves
Plants go through BOTH cell respiration and
photosynthesis.
How do you know? CO2 was produced when the light
was ________ and O2 is produced when the light was
_______
• cell respiration happens in the light/dark/both
• Photosynthesis happens in the light/dark/both
CO2 levels
• Cell respiration: CO2 levels _________________
• Photosynthesis: CO2 levels _________________
HOW PLANTS OBTAIN AND USE
ENERGY
Photosynthesis
CO2 + H2O + (light)  C6H12O6 + O2
Cell Respiration
O2 + C6H12O6  CO2 + H2O +(energy)
How animals obtain and use
energy
Animals eat C6H12O6 from plants/other animals
Cell Respiration
O2 + C6H12O6  CO2 + H2O +(energy)
MONO, DI, POLY
MONOMERS MAKE POLYMERS
• Monomer – the subunit to the larger whole. One
monomer is the smallest part. A monosaccharide is
a monomer of sugar
• Polymer – a larger molecule comprised of many
repeated subunits or many monomers put together.
BREAKING DOWN.. PUTTING
TOGETHER
• Dehydration synthesis - chemical reaction that
involves the loss of a water molecule from 2
monosaccharides joining together
• Hydrolysis – a disaccharide is broken apart into 2
monosaccharide with the addition of a water
molecule

• The body is water based, the water knows where to
be hydrolyzed in based on enzymes and bonds
