Photosynthesis Flashcards
What is the primary energy carrying molecule in our cells?
ATP
Photosynthesis synthesis using _____
Light
6CO2 + 6H2O —> C6H12O6 + 6O2 is equation for?
Photosynthesis
Cloroplast are…
(a) Organelle(s) in cell
(b) Protein in a cell
(c) A cell In plants
(d) Cotton eye Joe
(a) Organelles in a cell
Where is the chloroplast do the light
reactions occur?
A. thylakoid lumen
B. thylakoid membrane
C. inner membrane
D. stroma
B. thylakoid membrane
What are the three main stages of the Calvin cycle?
Fixation, Reduction, and Regeneration
Which enzyme is responsible for fixing CO₂ in the Calvin cycle?
RuBisCO (Ribulose-1,5-bisphosphate carboxylase/oxygenase
What is an enzyme, and how does it relate to cells and proteins
An enzyme is a biological catalyst, usually a protein, that speeds up chemical reactions in a cell without being used up.
Enzymes are essential for processes like metabolism, DNA replication, and cellular respiration.
What energy-carrying molecules from the light reactions power the Calvin cycle?
ATP and NADPH
Which molecule is regenerated at the end of the Calvin cycle to continue the process/repeat cycle
RuBP (Ribulose-1,5-bisphosphate)
What happens to the 6-carbon (Co2 added to 5-carbon) molecule formed in the first step of the Calvin cycle?
It immediately splits into two 3-carbon molecules called 3-PGA
What happens during the fixation phase of the Calvin cycle?
CO₂ is fixed to RuBP, breaking it into two molecules of 3-PGA. (3 Carbon)
What happens during the reduction phase of the Calvin cycle
ATP and NADPH convert 3-PGA into G3P (3 Carbon)
What happens during the regeneration phase of the Calvin cycle
Some G3P is used to regenerate RuBP using ATP (5 Carbon)
or
5x 3Carbon molecules transformed back into 3x 5Carbon molecule to repeat the cycle
How is carbon processed during the Calvin cycle
CO₂ is fixed into 3-PGA, reduced to G3P, and some G3P is used to regenerate RuBP (P-c-c-c-c-c-P)
Which stage in the Calvin cycle is a
5-carbon compound made?
D. Regeneration
Chloropyll are found where (Photosynthesis)
Inside Photosystem protien complexes
Which is inside tthe thlakoid membrane
which is inside The Cloroplasts
Chloropyll’s function (Photosynthesis)
Absorbs light energy
In Among us the sussy person is the
Imposter
