AP photosynthesis practice flashcard

Front

What is reduction in the context of photosynthesis?

Back

Reduction refers to the process when 3-PG is being converted into G3P.

Front

What is the role of the H+ concentration gradient in photosynthesis?

Back

The H+ concentration gradient is used to generate ATP.

Front

What is the Calvin cycle?

Back

The Calvin cycle is the light-independent reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugar.

Front

How many G3P molecules are needed to form one molecule of glucose?

Back

2 G3P molecules are needed to form one molecule of glucose.

Front

What color of light do green plants reflect?

Back

Green plants reflect green light.

Front

What is RuBP in photosynthesis?

Back

RuBP (Ribulose bisphosphate) is a 5-carbon sugar that is involved in the first step of the Calvin cycle.

Front

What is the function of rubisco?

Back

Rubisco is an enzyme that catalyzes the reaction of CO2 with RuBP to initiate the Calvin cycle.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

What is the primary product of the light-dependent reactions?

Back

The primary products of the light-dependent reactions are ATP and NADPH.

Front

What is the significance of NADPH in photosynthesis?

Back

NADPH is used as a reducing agent in the Calvin cycle to convert 3-PG into G3P.
