2 kinds of photophosphorylation
Cyclic and non-cyclic ph”””
If photophosphorylation is on plants, what do u call to the animal ones
Oxidative phosphorylation
What is the electron donor and acceptor of oxidative phosphorylation? which forms ____ on the end and is part on electron transport chain
Electron donor : NADPH
Acceptor : Oxygen
Forms water
If knina is ung sa oxidation phosphorylation, what abt the electron donor and acceptor of photophosphorylation
Vice versa
is found in chloroplasts which mediates electron transfer and contains an iron- sulfur cluster.
Ferredoxin - Ferredoxin (Fd)
Ferredoxin - Ferredoxin (Fd) contains?
iron- sulfur cluster
It is involved in the photosynthesis process where its iron atoms accept or discharge electrons when they are being oxidized or reduced
Ferredoxin - Ferredoxin (Fd)
is a 10 kD blue copper protein which is located in the lumen of the thylakoid where it functions as a mobile electron carrier shuttling electrons from Cytochrome b6f to P700 in Photosystem I.
Plastocyanin
Plastocyanin is a _______ which is located in the lumen of the thylakoid where it functions as a mobile electron carrier shuttling electrons from Cytochrome b6f to P700 in Photosystem I.
10 kD blue copper protein
are two important prenylquinones functioning as electron transporters in plants.
Plastoquinone (PQ) and ubiquinone (UQ)
They are involved in photophosphorylation and oxidative phosphorylation located in chloroplast thylakoids and mitochondrial inner membrane, respectively.
Plastoquinone (PQ) and ubiquinone (UQ)
The _____ provides the electronic connection between the photosystem I and photosystem II reaction centers of oxygenic photosynthesis and generates a transmembrane electrochemical proton gradient for adenosine triphosphate synthesis.
cytochrome b6f complex
generates a transmembrane electrochemical proton gradient for adenosine triphosphate synthesis.
cytochrome b6f complex
The cytochrome b6f complex provides the electronic connection between the photosystem I and photosystem II reaction centers of oxygenic photosynthesis and generates a _________________ for adenosine triphosphate synthesis.
transmembrane electrochemical proton gradient
___ is the last enzyme in the transfer of electrons during photosynthesis from photosystem I to NADPH. The NADPH is then used as a reducing equivalent in the reactions of the Calvin cycle
NADP+ reductase
used as a reducing equivalent in the reactions of the Calvin cycle
NADPH
After the energy from the sun is converted and packaged into (2)_________, the cell has the fuel needed to build food in the form of _______
ATP and NADPH.
carbohydrate molecules
The carbohydrate molecules made will have a backbone of _____. Where does the carbon come from? The carbon atoms used to build carbohydrate molecules comes from _______, the gas that animals exhale with each breath
carbon atoms
carbon dioxide
The ____ is the term used for the reactions of photosynthesis that use the energy stored by the light-dependent reactions to form glucose and other carbohydrate molecules.
Calvin cycle
In plants, carbon dioxide (CO2) enters the chloroplast through the _____ and diffuses into the ____ of the chloroplast-the site of the Calvin cycle reactions where sugar is synthesized. The reactions are named after the scientist who discovered them, and reference the fact that the reactions function as a cycle. Others call it the _______ to include the name of another scientist involved in its discovery
stomata. stroma
Calvin-Benson cycle
site of the Calvin cycle reactions where sugar is synthesized.
Stroma
The Calvin cycle is a part of _____, the process plants and other autotrophs use to create nutrients from sunlight and carbon dioxide. The process was first identified by __________ in ____
1957.
photosynthesis.
U.S. biochemist Dr. Melvin Calvin.
The Calvin cycle reactions can be organized into three basic stages:
fixation, reduction, and regeneration
In the stroma, in addition to CO2, two other chemicals are present to initiate the Calvin cycle:
an enzyme abbreviated RuBisCO, and the molecule ribulose bisphosphate (RuBP).
