Photosynthesis Flashcards
where do autotrophs get their energy
light
where do heterotrophs get their energy
food
what is the function of ATP in our cells
The ATP molecule releases chemical energy whenever a bond holding a phosphate group to the molecule is broken
where in a cell is ATP produced
mitochondria
Does ADP have stored chemical energy usable for the cell
No
What is the difference between ATP and ADP
ATP- adenine,ribose, and 3 phosphate groups
ADP- adenine, ribose, and 2 phosphate groups
Create an analogy for the difference between ATP and ADP
ATP- full on flashlight
ADP- dim flashlight
Define photosynthesis
light energy to chemical energy of glucose
Equation of photosynthesis
(reactants) 6CO2 + 6H2O+ light = (products) C6H12O6+ O2
What process converts light energy into chemical energy of glucose
photosynthesis
Where in the chloroplast does the light dependent reaction occur
thykloid
Where in the chloroplast does the light independent reaction occur
stroma
What are the two reactants of photosynthesis
6CO2 + 6H2O (carbon dioxide and water)
What are the two products of photosynthesis
C6H12O6+ O2 (glucose and oxygen)
What is the main function of pigments inside the chloroplasts
to trap light energy
What photosynthetic pigments do plants reflect
green
What is the function of NAPDH
high energy carrier
How would photosynthesis be affected if there were a shortage of NADP in the cells of plants
plants would have less energy
What are the reactants and products of the light dependent reaction
R- water and light
P- ATP, NAPDH, and oxygen
What are the reactants and products if the light independent reaction
R-ATP, NAPDH, and carbon dioxide
P- Glucose and water
What two high energy carrier molecules are made during the light dependent reaction and used in the light independent reaction
ATP and NADPH
Why do plants need to make glucose
it is its source of energy
In what form do plants store their extra glucose
cellulose in their cell wall
Where does the hydrogen come from that plants use to make glucose
water
