Cell Energy Review

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 product of photosynthesis?

Back

The primary product of photosynthesis is glucose (sugar), which is used by plants for energy.

Front

What role does oxygen play in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis, released into the atmosphere during the light-dependent reactions.

Front

What are light-dependent reactions?

Back

Light-dependent reactions are the first stage of photosynthesis, occurring in the thylakoid membranes, where sunlight is converted into chemical energy (ATP and NADPH) and oxygen is produced.

Front

What is the Calvin cycle?

Back

The Calvin cycle is the second stage of photosynthesis, occurring in the stroma, where ATP and NADPH are used to convert carbon dioxide into glucose.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is a molecule that carries energy within cells, consisting of adenine, ribose, and three phosphate groups.

Front

How many phosphate groups are in ATP?

Back

ATP has 3 phosphate groups.

Front

What gas is used in the Calvin cycle?

Back

Carbon dioxide is used in the first step of the Calvin cycle.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis converts carbon dioxide and water into glucose and oxygen, while cellular respiration uses glucose and oxygen to produce carbon dioxide, water, and energy.

Front

What is the significance of measuring oxygen production in photosynthesis?

Back

Measuring oxygen production helps scientists determine the rate of photosynthesis, as oxygen is a direct byproduct of the light-dependent reactions.
