Honors Bio - Photosynthesis Flashcard #2

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 a 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

What is the role of light in photosynthesis?

Back

Light provides the energy needed to drive the reactions of photosynthesis, particularly in the light-dependent reactions.

Front

What is the chemical equation for photosynthesis?

Back

6CO2 + 6H2O + light energy -> C6H12O6 + 6O2.

Front

What happens during the light-dependent reactions?

Back

During the light-dependent reactions, light energy is absorbed by chlorophyll, water is split, and ATP and NADPH are produced.

Front

What is the Calvin cycle?

Back

The Calvin cycle is the set of light-independent reactions in photosynthesis where carbon dioxide is fixed into glucose using ATP and NADPH.

Front

What is NADP+ and its role in photosynthesis?

Back

NADP+ is an electron carrier that accepts electrons during the light-dependent reactions and is reduced to NADPH.

Front

Why do leaves appear green?

Back

Leaves appear green because chlorophyll reflects green light and absorbs other wavelengths, particularly red and blue.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a process of passive transport where molecules move across a membrane via specific transport proteins.
