Photosynthesis Review - Honors

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What is the primary pigment involved in photosynthesis?

Back

Chlorophyll is the primary pigment involved in photosynthesis, responsible for absorbing light energy.

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

Where do the light-dependent reactions take place?

Back

The light-dependent reactions occur in the thylakoid membranes of chloroplasts.

Front

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

Back

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

Front

What is the Calvin cycle?

Back

The Calvin cycle is the series of biochemical reactions that take place in the stroma of chloroplasts, where carbon dioxide is fixed into glucose.

Front

What molecule does carbon dioxide combine with in the Calvin cycle?

Back

In the Calvin cycle, carbon dioxide combines with RuBP (ribulose bisphosphate) to form 3-PGA.

Front

What is the role of RuBP in photosynthesis?

Back

RuBP (ribulose bisphosphate) is a 5-carbon sugar that acts as a carbon dioxide acceptor in the Calvin cycle.

Front

What is the overall equation for photosynthesis?

Back

The overall equation for photosynthesis is 6CO2 + 6H2O -> 6O2 + C6H12O6.

Front

What is the significance of photosynthesis for life on Earth?

Back

Photosynthesis is crucial for life on Earth as it produces oxygen and organic compounds that serve as food for most living organisms.
