PGA

Question 6

Which compound is produced during regeneration?

Revolt · Accepted Answer

RuBP

Question 7

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

Revolt · Accepted Answer

phosphate group

Question 8

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

Revolt · Accepted Answer

The L-D reactions require light energy and water, and the L-IND reactions require ATP, NADPH, and CO sub 2 .

Question 9

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.

Question 10

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.
