Photosythesis Flashcards
how does photosynthesis transforms light energy into chemical energy.
converting carbon dioxide plus water into sugars plus released oxygen
how does cellular respiration breaks down food and oxygen to form new compounds and energy
through a series of chemical reactions, essentially “burning” them to produce carbon dioxide, water, and energy in the form of ATP . THINK KREBS CYCLE, GLYCOLYISIS AND Electron Transport Chain
How is photosynthesis related to the to food you eat?
The energy stored in carbohydrate molecules from photosynthesis passes through the food chain.
Where does photosynthesis happen?
Chloroplast
Why do plants look green?
Chloroplasts (and plants!) look green because the wavelengths that are NOT absorbed are reflected to our eyes.
Inputs for Light Dependent Reactions
Light, water, NADP+, ADP + Pi
Light Independent Reactions Inputs?
(Aka Calvin Cycle)
ATP and NADPH, CO₂ 2 ( NO LIGHT)
Process of Light Independednt Reactions
Energy from ATP and NADPH is used to fix 6 carbon dioxide into 1 glucose molecule
How are photosynthesis and cellular respiration related?
The inputs of one are the outputs of the other
photosynthesis
performs in _ only
autotrophs
Cellular respiration perfroms in
both autotrophs and heterotrophs
A scientist puts a piece of a water plant into each of two test tubes filled with water. She seals the test tubes so that there are no bubbles in them. Then she places one of them in a dark closet and one of them in front of a sunny window. Two hours later, the dark test tube still has no bubbles, but the one placed near the window now as bubbles in it. What gas is in the bubbles?
Oxygen
The oxygen produced during photosynthesis comes directly from the
Splitting of water (H2O) molecules
The main pigment in photosynthesis is…
chlorophyllThis
difference between autotrophs and heterotrophs?
Autotrophs typically generate energy from inorganic materials, whereas heterotrophs generate energy from organic materials.
inputs of photosynthesis?
Carbon dioxide,Sunlight (solar energy) and water
factors affect the rate of photosynthesis?
1)The amount of light
2)The amount of CO2
3)The amount of water
4) The number of thylakoids
