Chapter 6 & 7 (Photosythesis and Cellular Respiration) Flashcards
Photosythesis
the transformation of light energy from the sun to chemical energy in the form of organic compounds
Autotroph
Organisms that produce their own organic food molecules as well as the organic food molecules for all nonautotrophs
What is the initial source of energy for all life
The Sun
Heterotroph
Organisms that acquire their own food through the consumption of other organisms
Biochemical Pathway
Cellular Respiration and Photosythesis
Write the balanced equation for photosythesis
6C0sub2+6Hsub2O+Light—>Csub6Hsub12Osub6+6Osub2
In which organelle does photosynthesis occur
Chloroplast
In which organ of the plant does photosynthesis occur
Leaves
What happens in a light reaction
solar energy is captured and converted into chemical energy in the form of ATP and NADPH
Where does the oxygen come from that is produced during the light reaction
Water
What two molecules are produced in a light reaction
ATP
NADPH
Thylakoids
Membranous sacs in the stroma that contain chlorophyll
Grana
The connected and layered stacks of thylakoids
What 3 substances are produced when water is split during the light reaction
chemical energy in the form of ATP and NADPH. O2 is also produced.
Calvin Cycle
Chemical energy is used to produce organic food molecules from COsub2 Occurs in the stroma of the chloroplast
Stroma
Dense fluid in the chloroplast
Where does the carbon come from that is used by Calvin Cycle to make organic compounds
Photosynthesis
What is the most common way plants produce organic compounds
Cellular Respiration
List the colors of the visible spectrum (Wavelength, Frequency, and energy)
Red Orange Yellow Green Blue Indigo Violet
Photons
tiny mass less bundles of radiation
Pigments
compounds that absorb light
Chlorophyll
the green pigment found within plastids called chloroplasts
Which pigment is directly involved in photosythesis
Chlorophyll-a
List 2 accessory pigments
Chlorophyll b
Carotenoids
