Photosynthesis and ATP

Front

What is photosynthesis?

Back

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

Front

What are the raw materials needed for photosynthesis?

Back

The raw materials needed for photosynthesis are carbon dioxide (CO2) and water (H2O).

Front

What is the main product of photosynthesis?

Back

The main product of photosynthesis is glucose (C6H12O6), which serves as an energy source for plants.

Front

What role do chloroplasts play in photosynthesis?

Back

Chloroplasts are organelles in plant cells that contain chlorophyll and are responsible for capturing sunlight to perform photosynthesis.

Front

What is chlorophyll?

Back

Chlorophyll is a green pigment found in chloroplasts that absorbs light energy, primarily from the sun, and is essential for photosynthesis.

Front

Why is sunlight considered the ultimate source of energy for living things?

Back

Sunlight is considered the ultimate source of energy because it provides the energy needed for photosynthesis, which produces glucose that fuels most life forms.

Front

What is ATP and why is it important?

Back

ATP (adenosine triphosphate) is a molecule that stores and transfers energy within cells, making it essential for various cellular processes.

Front

How is ATP produced during photosynthesis?

Back

ATP is produced during the light-dependent reactions of photosynthesis when sunlight is captured and used to convert ADP and inorganic phosphate into ATP.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis converts light energy into chemical energy (glucose), while cellular respiration converts that chemical energy into usable energy (ATP) for cells.

Front

What happens to the oxygen produced during photosynthesis?

Back

The oxygen produced during photosynthesis is released into the atmosphere as a byproduct, which is essential for the survival of aerobic organisms.
