Biology 20 - Photosynthesis Flashcards
(32 cards)
What is the Storma?
Interior space filled with a protein rich semi-liquid
What are Thylakoids?
Located in the stroma; membrane bound sacks, stacked on top of eachother (Grana)
What are Grana’s?
Thylakoids stcked on top of eachother
What is the Chlorophyll? what are the 2 types of chlorophyll?
Chlorophyll is a light abosrbing pigment (Thylakoid)
Chlorophyll A: Primary light abosrbing pigment
Chlorophyll B: Accessory Pigment
Thylakoid Lumen is?
Interior space of the thylakoid, filled with water
Oxidization is?
Is the loss of electron (LEO)
NADP+ is REDUCED to NADPH
Reduction is?
The Gain of electron (GER)
NADPH is OXIDIZED to NADP+
What is the Photosynthesis Formula?
6CO2 + 6H2O + Light = C6H12O6 + 6O2
Carbon dioxyde + Water + Light = Glucose + Oxygene gas
It’s an endothermic reaction
What are the inputs and outputs of the Light Dependent.
The Light dependent happens in the THYLAKOID.
Inputs: Light, H2O, ADP + P
Outputs: O2, ATP, NADPH
What are the inputs and outputs of the Light Independent.
The light Independent happens in the STROMA.
Input: CO2, ATP, NADPH
Output: G3P (2 G3P = Glucose)
What are the Outputs/Product in the Calvin Cycle?
G3P, NADP+, ADP + P
What Colours do the Chlorophyll pigment absorbs to transmit the colour green?
Violet, Blue, Red.
What is Photolysis?
Photons (light) of light split the water molecules to release e-and H+. OXYGENE is a waste product of photolysis.
Photon energy is converted to potential energy, meaning?
The exited electrons ‘‘Jumps’’ and leaves the photosystem.
What happens when a photon of light hits PSII?
Anelectron is exited and elevated to a higher energy level.
What happens when the electron carriers in the electron transport (ETC) chain?
It releases energy which is used to move electrons from STROMA to THYLAKOID, using ATP (Active transport)
How many Carbon dioxyde’s are needed to create 1 Glucose molecule?
6 G3P needed to create 1 Glucose. 3 G3P per cycle.
Where does the Calvin Cycle occur?
It occurs in the Stroma
How many times the cycle does it need to produce 1 Glucose? How many ATP and NADPH does it produce when the cycel goes around twice?
The Calvin Cycle goes around twice because you need 2 G3P to create 1 Glucose. Having the cycel go around twice produces 18 ATP and 12 NADPH.
What is Carbon Fixation
3 CO2 combine with RuPB to create 6 unstble carbon molecules.
What is Reduction?
Energy from 6 ATP + 6 NADPH added to 3 carbon molecules, creating 6 G3P
What is Regenereation?
3 ATP combine with 5 G3P, regenerate RuBP and restarts the reaction.
What is Chemiosmosis?
It’s the movements of Hydrogen Ions from a [HIGH] concentration (In Lumen) toa [LOW] concentration (in Stroma)
