Question 4

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

Revolt · Accepted Answer

carbon dioxide

Question 5

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

Revolt · Accepted Answer

ATP supplies the energy to produce glucose and other carbohydrates.

Question 6

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

Revolt · Accepted Answer

energy

Question 7

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

Revolt · Accepted Answer

hot and dry

Question 8

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

Revolt · Accepted Answer

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

Question 9

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

Revolt · Accepted Answer

the atmosphere

Question 10

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

Revolt · Accepted Answer

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