cell energy test 5 Flashcards
whats the photosynthesis formula
C02 and water reacts with sunlight with chlorophyll to form glucose and oxygen
where does the light dep reaction occur
in the thykaloid
what happens in light dependant reaction
water is split into oxygens
what does water splitting into oxygen always require
sun light or light to be present
what is another naem for the light indpendant cycle
the calvin cycle
where does the calvin cycle occur
in the stroma
what happens in light independant reaction
carbon in converted into glucose
what is glucose
C6H12O6
what type of molecule is glucose
a monosaccaride
where does the plant absorb sunlight
on the leaves
why do only the leaves absorb sunlight
because they contain chlorophyll
why is chlorophyll green
because it absorbs other colors of the light spectrum but not green so green is reflected
how does phtotsynthesis gets its energy
by absorbing wavelengths of light
which wavelengths does chlorophyll absorb best
red and blue
which colors of the visible light spectrum have the most plant growth
red and blue
whihc colors of the visisble light spectrum have the least plant growth
green
what does white light do to plant growth
it makes it grow moderately
where does CO2 enter the plant
through the stomata
what do guard cells do
helps gas exchange , prevents excessive water loss
what is an open guard cell
turgid
what do guard cells cover
the stomata
where does H2O come from for photosynthesis
the roots
where do the plant’s nutrients come from
the roots
what type of membrane does a chloroplast have
a double membrane
what are thykaloid
sacs in chloroplasts that contain chlorophyll
what are grana
stacks of thykaloids
can animals do phtosynthesis
no
factors that affect the rate of phtosyntheisis
temperature, co2 concentration, water , light intensity,
what parts of the plant cell are visible under a light microscope
cell wall, chloroplasts, central vacuole ,
whats the cellular respiration equation
glucose and oxygen react to form ATP water and carbon dioxyde
what is cellular respiration
the opposite of photosynthesis
do both plants and animals do cellular respiration
yes
what are the reactants in cell respiration
oxygen and glucose
what are the products of cell respiration
water and carboon dioxyde and ATP
what factors affect the rate of cellular respiration
temperature , glucpse concentration and oxygen concentration
what type of respiration is described in the orginal equation
aerobic respiration
what does aerobic respiration require
oxygen present
what organelle does aerobic respiration take place
the mitochondria
which type of respiration uses the krebs cycle
aerobic
what does aerobic respiration release
water and carbon dioxyde and atp
what is the main goal of any respiration
to make atp
when an organism dosent have oxygen presewnt what type of respiration is it
inaerobic respiration
what is fermentation
when there is no oxygen present in cell respiration, so lactic acid or ethanol is produced as a by product
what type of respiration is faster
inaerobic respiration
whihc prganism have to always do inaerobic respiration
one without a mitochondria
when do animals (humans) have to do inaerobic respiration
when they can’t produce enough oxygen
which type of respiration makes more atp
aerobic respiration
what does glucose need to become before any respiration
pyruvate
how does the folding of the inner mitochondrial membrane benefit cellular respiration
it increases surface area which allows more respiration
where does inaeronic respiration take place
the cytoplasm
what is the normal BTB color
green
what is BTB with co2
yellow
what is BTB with oxygen
blue
what color is BTB and snail
yellow
what color is BTB and elodea
blue
what color is BTB snail and elodea
green
what color is BTB, snail, elodea in a dark place
yellow
autrotroph
organsiam that can make organic food from inorganic substances
hetrotroph
organism that cannot makes its own organic food form inorganic molecules
inorganic
not made from carbon
example of inorganic substances
co2 water oxygen
organic
substance containing carbon-based compunds
example of organic substance
glucose
stoma or stomata
tiny opening for gas exchange
light intensity
the power of a light wave length
calories
a measure of energy
what does one calories represent
the enrgy to raise one gram of water by one degree celsius
glycolysis
Glucose becoming pyruvate
