Dark Stage Flashcards
Where do the reactions of the dark stage take place?
In the stroma of the chloroplast
What controls the reactions of the dark stage?
Enzymes
The reactions of the dark stage are controlled by enzymes, what does this mean for the rate of reaction?
This means the dark stage is affected by temperature
Where does the carbon dioxide needed for the dark stage come from?
The air or respiration
What is the first step in the dark stage?
Carbon dioxide from the air or from respiration enters the chloroplast
During the dark stage, where does carbon dioxide enter?
Carbon dioxide enters the chloroplast
What is the second step in the dark stage?
Protons/H+ and electrons are released from NADPH to convert/reduce carbon dioxide to carbohydrate (glucose)
What is released from NADPH?
Protons/H+ and electrons
Where does the NADPH come from?
The light stage
What is the NADP+ produced by the dark stage needed for?
The light stage
What carbohydrate is made by the dark stage?
Glucose
What is reduction?
The addition of electrons
Where do the hydrogen ions and electrons come from?
The breakdown of NADPH made in the light stage
What supplies the energy needed to form glucose?
It comes from the conversion of ATP made in the light stage to ADP and phosphate
Where does ATP come from?
The light stage
