CO2 concentration
Carbon dioxide in photosynthesis
Carbon dioxide basics
100

When COâ‚‚ concentration is low, the rate of photosynthesis is generally this.


What is low?


100

This process uses carbon dioxide, water and light energy to produce glucose and oxygen.


What is photosynthesis


100

This colorless, odorless gas has the chemical formula CO2


What is carbon dioxide?


200

At low CO2 concentration, this substance acts as a limiting factor for photosynthesis.


What is carbon dioxide?


200

Carbon dioxide enters the Calvin cycle during this process.


What is carbon fixation?


200

How many bonds can carbon form 

What is four bonds 

300

As CO2 concentration increases, the rate of photosynthesis initially does this.


What is increase?


300

During carbon fixation, COâ‚‚ combines with this five-carbon compound.


What is RuBP (ribulose bisphosphate)?


300

In photosynthesis, carbon dioxide provides the carbon needed to produce these organic compounds


What is glucose

400

The rate of photosynthesis continues increasing as long as CO2 remains the main limiting factor.


What is true?


400

This enzyme catalyzes the reaction between CO2 and RuBP.


What is RuBisCO?


400

Carbon dioxide is obtained by plants from this surrounding source.


What is the atmosphere?


500

Eventually, increasing CO2 concentration has little or no additional effect because another factor becomes limiting.


What is the maximum rate/plateau?


500

The products formed after carbon fixation are eventually used to produce compounds such as glucose, starch and amino acids.


What are carbohydrates and other organic compounds?


500

Carbon dioxide is described as the essential substrate and primary carbon source for this stage of photosynthesis.


What is the light-independent stage (Calvin cycle)?
