Cellular respiration and photosynthesis

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

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 main products of cellular respiration?

Back

The main products of cellular respiration are ATP (energy), carbon dioxide, and water.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment found in the chloroplasts of plants that absorbs light energy, primarily from the sun, to drive the process of photosynthesis.

Front

What is the equation for photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is the equation for cellular respiration?

Back

C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP.

Front

What is the significance of the number '6' in the photosynthesis equation?

Back

The number '6' indicates that there are six molecules of each reactant (CO2 and H2O) and six molecules of the product (O2) involved in the reaction.

Front

How do plants obtain carbon dioxide for photosynthesis?

Back

Plants obtain carbon dioxide from the atmosphere through small openings in their leaves called stomata.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis and cellular respiration are interconnected processes; the products of photosynthesis (glucose and oxygen) are the reactants for cellular respiration, and vice versa.
