Front

What is the maximum rate of photosynthesis dependent on?

Back

The maximum rate of photosynthesis is dependent on the speed of the Calvin cycle, which can only go as fast as the light reactions.

Front

What role does NADPH play in photosynthesis?

Back

NADPH carries electrons to the Calvin cycle.

Front

How many G3P molecules are required to synthesize one molecule of glucose?

Back

Two G3P molecules are required to make one molecule of glucose.

Front

What is the primary function of the Calvin cycle in green plants?

Back

The primary function of the Calvin cycle is to construct simple sugars from carbon dioxide.

Front

What enzyme is responsible for carbon fixation in C3 photosynthesis?

Back

The enzyme responsible for carbon fixation in C3 photosynthesis is RuBisCo.

Front

What are the light reactions in photosynthesis?

Back

The light reactions are the first stage of photosynthesis where light energy is converted into chemical energy in the form of ATP and NADPH.

Front

What is the significance of G3P in photosynthesis?

Back

G3P (glyceraldehyde-3-phosphate) is a three-carbon sugar that is a direct product of the Calvin cycle and is used to form glucose and other carbohydrates.

Front

How does increasing carbon dioxide concentration affect photosynthesis?

Back

Increasing carbon dioxide concentration can enhance the rate of photosynthesis up to a certain point, after which it plateaus due to limitations in the Calvin cycle.

Front

What is the relationship between light intensity and the rate of photosynthesis?

Back

As light intensity increases, the rate of photosynthesis typically increases until it reaches a saturation point.

Front

What are the products of the light reactions of photosynthesis?

Back

The products of the light reactions are ATP, NADPH, and oxygen.
