Photosynthesis Flashcards
What molecules enter the light dependent reaction
H2O-water
light
What is the equation for photosynthesis
6CO2+ 6H2O—-> C6H12O6+ 6 O2
What molecules are produced in the light dependent reaction
NADPH
ATP
Oxygen
What molecules enter the light independent reactions
Carbon dioxide
What molecules are produced in the light independent reactions
Glucose
What is the name of the Cylic reaction that takes place after light reaction
Calvin cycle/ dark reaction
Where does the energy of food originally come from
The sun- plants use light energy to make food
Autotrophs are
Organisms that make their own food
What is an example of an autotroph
Plant
Heterotrophs are
Organisms that obtain energy from food they eat
Examples of heterotrophs are
Animals
What is one of the principal chemical compounds that living things used to store energy
ATP
How is ATP different from ADP
ATP has three phosphate groups and ADP has two phosphate groups
What are three factors that affect the rate at which photosynthesis occurs
Temperature – increases with temperature
Carbon dioxide – increases with increased in carbon dioxide concentration
Light energy – requires energy which is obtained from light
What is the ganum
Stack of thylakoids together
What is the Lemela
Stick like structure that connects the thylakoids together
Where is the site of photosynthesis
Chloroplasts
What is the stroma
The stroma is the liquid that sells the site of photosynthesis (chloroplast)
What occurs during cellular respiration
Plants break down sugars during cellular respiration for food for themselves
How does the overall reaction for photosynthesis compared to the overall reaction for cellular respiration
It is the reverse of the overall reaction for cellular respiration
Mirrored
What plant pigments are involved in photosynthesis
Chlorophyll a, chlorophyll B
The light reaction takes place in the
Thylakoids
Calvin cycle takes place in the
Stroma
Happens to watermelon kills in the light reactions
What are molecules are split to get electrons ions and oxygen gas
What to products of the light reactions are used up in the Calvin cycle
ATP and NADPH
What happens to carbon dioxide molecules in the Calvin cycle reactions
Carbon dioxide molecules are combined with each other and with the electrons from NADPH to form glucose
How can cells store sugar that is produced in photosynthesis
It is stored as starch
Define thylakoids
Small disc likes compartments composed of membranes that of the site of light dependent photosynthesis
