|
what is the total of all chemical reactions in an organism
|
metabolism
|
|
|
what can cause changes in cells by breaking them apart or putting things together
|
enzymes
|
|
|
what does each chemical reaction in a cell require
|
a specific enzyme
|
|
|
what is the substance that is affected by the enzyme called
|
substrate
|
|
|
organisms that make there own food
|
producers
|
|
|
where do producers get energy
|
the sun
|
|
|
what do producers so with the energy from the sun
|
convert it into usuable form
|
|
|
organisms that cannot make there own food
|
consumers
|
|
|
how do they get food
|
they break down and use energy from other organisms
|
|
|
the process of converting light energy into chemical energy
|
photosynthesis
|
|
|
producers convert light energy into what
|
sugar which they use as food
|
|
|
why are producers green in color
|
they contain a pigment called chlorophyl
|
|
|
what does chlorophyl do
|
it captures light
|
|
|
where is chlorophyl found
|
in the chloroplasts
|
|
|
what does the process of photosynthesis use
|
6 carbon dioxide and water molecules
sunligh |
|
|
what does phosynthesis produce
|
molecule of sugar and a molecule of oxygen
|
|
|
during photosynthesis do plants make more sugar then they need
|
yes
|
|
|
where is the extra sugar that plants make stored
|
as carbohydrates
|
|
|
what do plants use carbohydrates for
|
growth
maintence reproduction |
|
|
chemical reactions that break down food molecules int simpler substances and release the enery is calleed what
|
cellular respiration
|
|
|
what does cellular respiration require
|
enzymes
6 molecules of oxygen 1 molecule of glucose |
|
|
what does cellulare respiration produce
|
6 molecules of water and carbon dioxide
chemical energy |
|
|
where does cellulare respiration begin
|
in the cytoplasm
|
|
|
what happens in the cytoplasm
|
enzymes break the carbohydrates into simpler molecules
|
|
|
after the enzymes breakdown the carbohydrates into simpler molecules where do they go next
|
the mitochondria where they are broken down further
|
|
|
what do the molecules broken down in the mitochrondria release
|
atp
|
|
|
What is is whe cells do not have enough energy for cellular respiration
|
fermination
|
|
|
what is fermentation
|
release energy rom glucose molecules
|
|
|
where does fermination start
|
cytoplasm
|
|
|
does fermentaion occur in the mitochondria
|
no
|
|
|
does fermination produce alot or little energy
|
little
|
|
|
what is the end result of fermination
|
lactic acid
|
|
|
explain why we need plants
|
plants producers give us food and release oxygen
|
