Photosynthesis / Cellular respiration

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 chloroplasts?

Back

Chloroplasts are organelles found in plant cells and some algae that conduct photosynthesis, containing chlorophyll which captures light energy.

Front

What is the primary function of cellular respiration?

Back

The primary function of cellular respiration is to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products.

Front

What is the Kreb Cycle?

Back

The Kreb Cycle, also known as the citric acid cycle, is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetate derived from carbohydrates, fats, and proteins.

Front

What is the role of carbon dioxide in photosynthesis?

Back

Carbon dioxide is one of the key reactants in photosynthesis, where it is used along with water and light energy to produce glucose and oxygen.

Front

Why do trees benefit from increased levels of CO2?

Back

Trees benefit from increased levels of CO2 because it enhances their ability to perform photosynthesis, leading to increased growth and biomass.

Front

What is the importance of the nitrogen cycle?

Back

The nitrogen cycle is important because it recycles nitrogen in various forms through the environment, making it available for use by living organisms, particularly plants.

Front

What is produced during cellular respiration?

Back

During cellular respiration, carbon dioxide and water are produced as waste products, along with ATP as the main energy currency.

Front

How does photosynthesis affect the atmosphere?

Back

Photosynthesis affects the atmosphere by reducing carbon dioxide levels and increasing oxygen levels, which is essential for the survival of aerobic organisms.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis and cellular respiration are interconnected processes; photosynthesis converts light energy into chemical energy, while cellular respiration converts that chemical energy into usable energy (ATP) for cells.
