Importance of photosynthesis to living organisms - 🧠 ANSWER ✔✔plants
use photosynthesis to produce food, and those plants feed the biosphere
Chloroplast - 🧠 ANSWER ✔✔organelle found in cells of plants and some
other organisms that captures the energy from sunlight and converts it into
chemical energy
Main structures involved photosynthesis - 🧠 ANSWER ✔✔Chloroplast-
double membrane
- stroma: liquid
,Grana- stacks of thylakoids/ all light reactions going to occur
Luma- inside of the thylakoids
Substrates and products of photosynthesis - 🧠 ANSWER ✔✔Substrates:
H2O, CO2, Sunlight
Products: ATP and NADPH
Explain how plants absorb energy from sunlight - 🧠 ANSWER ✔✔-
Chlorophyll A and B: captures light for photosynthesis
- light goes from ground state to excited state
-
short wavelength - 🧠 ANSWER ✔✔high frequency (bluish colors, high-
pitched sounds)
long wavelength - 🧠 ANSWER ✔✔low frequency (reddish colors, low-
pitched sounds)
How/Where does photosynthesis take place? - 🧠 ANSWER ✔✔-
Photosynthesis takes place in the chloroplasts by absorbing water, light,
and CO2 gas
, thylakoid membrane - 🧠 ANSWER ✔✔The photosynthetic membrane within
a chloroplast that contains light gathering pigment molecules and electron
transport chains.
Photosystem II - 🧠 ANSWER ✔✔- One of two light-capturing units in a
chloroplast's thylakoid membrane or in the membrane of some prokaryotes
- comes before PS 1
- The electrons are returned to Chlorophyl A by splitting water, resulting in
oxygen as a water product
Photosystem 1 (PS1) - 🧠 ANSWER ✔✔- A light capturing enzyme in the
thylakoid membrane of a chloroplast; reduces NADP+ to NADPH.
-
Electron Transport Chain (ETC) - 🧠 ANSWER ✔✔uses the high-energy
electrons from the Krebs cycle to convert ADP into ATP
Inputs of Calvin Cycle - 🧠 ANSWER ✔✔CO2, ATP, NADPH
Outputs of Calvin Cycle - 🧠 ANSWER ✔✔ADP, NADP+, G3P
Calvin Cycle - 🧠 ANSWER ✔✔3 phases: - Carbon fixation
