BIO - Ch 8. Photosynthesis

autographs (self feeders)

make their own sugars from inorganic substances and energy

what are some examples of self feeders

plants, algae and certain bacteria

heterotrophs (different feeders)

obtains nutrients by feeding on other organisms

what are some examples of different feeders

animals and fungi

thylakoid

pancake like structures inside a plant cell’s chloroplast

granum

the stack of pancake like structures in a plant cell’s chloroplast

stroma

aqueous space in a plant cell’s chloroplast

what is part one of photosynthesis

light reactions

what do light dependent reactions start with

sunlight, water, NADP+ and ADP

what does light dependents reactions end with

oxygen, NADPH, ATP

do light dependent reactions need light

yes, they are light dependent

what is absorbed in light dependent reactions

light from the sun

what happens at the end of light dependent reactions

energy is converted to ATP or NADPH then get sent to the Calvin cycle

what is the overview of light dependent reactions

captures energy from the sunlight and converts it into energy stored in ATP and NADPH

where does light dependent reactions take place

in the thylakoid membrane of the chloroplast

what electron carriers are reduced/oxidized in light dependent reactions

NADP+ is reduced to NADPH

is ATP produced or used in light dependent reactions

produced

what is part two of the photosynthesis

the Calvin cycle/light independent reactions

what do light independent reactions start with

CO2, NADPH an ADP

what do light independent reactions end with

glucose, NADPH+ and ADP

what type of reaction is the Calvin cycle

endergonic/anabolic

does the Calvin cycle require light

no, but it requires the products from light dependent reactions

what is the overview of light independent reactions

uses chemical energy of ATP and NADPH to convert CO2 to C6H12O6 (glucose)

where do light independent reactions occur

in the stroma

what electron carriers are reduced/oxidized in light independent reactions

NADPH is oxidized to NADP+

is ATP produced or used in light independent reactions

ATP is used

what can effect the rate of photosynthesis

intensity/color of light, concentration of CO2, amount of water and temperature

chemical equation for glucose

C6H12O6

photosynthesis equation

CO2 + H2O + energy (light) → C6H12O6 +O2

what is the equation for cellular respiration

C6H12O6 +O2 → energy (ATP) CO2 +H2O

do plants need mitochondria

YES, they need mitochondria to make ATP

what type of reaction is light dependent

exergonic/catabolic

what types of cells do cellular respiration

all organisms (including plants) do cellular respiration

does photosynthesis build or break bonds

builds bonds

does cellular respiration build or break bonds

breaks bonds

what is the difference between the equation of photosynthesis and cellular respiration

their the same equation just flipped, with different types of energy
