Light Independent Reactions in Photosynthesis For Winners

Which compound is a metabolic intermediate of the light-independent reactions in photosynthesis?

3-PGA

How do ATP and NADPH connect light-dependent and light-independent reactions in photosynthesis?

ATP and NADPH are produced in the light-dependent reactions and used in the light-independent reactions.

What is one role of ATP in the light-independent reaction of photosynthesis?

ATP supplies the energy to produce glucose and other carbohydrates.

What is required for both the light-dependent and light-independent reactions to proceed?

Energy

Which is the best hypothesis for the scientific question "How does light intensity affect the rate of photosynthesis?"

If the distance between the source of light and the plant is increased, the rate of photosynthesis will decrease.

Which is the best hypothesis for the scientific question "How does light intensity affect the rate of photosynthesis?"

Light intensity has an impact on the rate of photosynthesis.

Which is the first step in the scientific method?

NOT construct a hypothesis

During reduction, 3-PGA reacts with ATP and NADPH. What does ATP contribute to the reaction?

NOT electrons phosphate group

Which is required for the light-independent reactions in photosynthesis to occur?

NOT sunlight carbon dioxide

Which is an important difference between light-dependent (L-D) and light-independent (L-IND) reactions in photosynthesis?

The L-D reactions require light energy and water, and the L-IND reactions require ATP, NADPH and CO2.

Which statement about the light-independent reactions in photosynthesis is true?

They produce ATP and NADPH.

In which type of environment are plants most likely to use a C4 pathway of carbon fixation?

hot and dry

What is the source of the carbon dioxide that is used in photosynthesis?

the atmosphere

Which process occurs during the light-dependent reactions in photosynthesis?

water molecules are split
