Energy for the cell to use
ability to work
_________________is never created or changed
what is importance of food web?
energy is lost in the form of heat (usually 90%)
What is importance of photosynthesis?
light energy to chemical energy
What does ATP stand for?
A 5C sugar called ribose is
Key to store and releasing energy is
3 Phosphate groups
ADP has__________________________ and
2 phosphate groups and store energy
ATP bonds release
energy by breaking bonds
ATP bonds store
energy by forming bonds
What are uses for ATP?
-Movement by cilla and flagella
-Na-K pump in active transport
-produce light(ex. fireflies)
what is meaning of photo and synthesis?
synthesis: putting together
Photosynthesis convert __________________into _____________________ that is stored in ___________________
light energy, chemical energy, carbohydrate bonds
what are ingredients for photosynthesis?
water, sunlight, and co2
What are white light made up of?
made of all colors/ pigments
Blue/violet light is __________________energy, _________________wavelength
higher and shorter
plants _______________different colors of light
main pigment is
chloroplast absorbs all colors but
chloroplast absorbs all colors but __________________green
chlorophyll is in
chloroplasts absorbs __________________energy and transfers to electrons
What is equation of photosynthesis?
6H2O + 6 CO2 - C6 H12 O6 +6O2
The electron acceptor ________________and ____________________enter the light reaction
NADP + and ADP
NADP+ accepts 2 _____________energy electrons and a ___________________ion making ___________________
high, hydrogen, NADPH
ADP is converted to
Without these product (NADP+, ADP, NADPH, ATP) from the light reaction, __________________could not proceed
what are inputs of light-dependent reaction?
light, water, NADP+, ADP
light -dependent reaction occurs in the
Light dependent reaction is the conversion of _________________energy to _______________and ___________________
light, ATP, NADPH
During the light-dependent reaction, oxygen is released through the
1. Photosystem 11: light energy is absorbed and sends electrons through electron transport chain(ETC)
*H2O is the source of electrons, hydrogen, and oxygen
2. Electrons more along ETC and pump H+ into the thylakoid space
3. Photosystem 1: electrons are re-energized and NADP+ picks up electrons and H+(NADPH formed)
4. H+ builds up in thylakoid space, exits from high to low to stroma
the process light reaction
light reaction steps occurs through
ATP synthase- a turbine that adds P to ADP=ATP
Where does Calvin Cycle takes place?
in the stroma
Calvin Cycle use _________and ____________to make carbohydrates, glucose, starch(long chain of stored glucose), and cellulore(tough fibers that give plansts stength and rigidity)
The products of the light reaction fuel the
the products of the calvin cycle fuel the
what are factors that affect photosynthesis?
-temperature: enzyme function best at 0 to 35 degree c
-intensity of light(amount of light): higher intensity light increases rate of photosynthesis
-access to water: water loss can slow down photosynthesis
what are two major photosynthesis process?
light dependent reactions and light independent reactions
