Energy Transformation - Photosynthesis & Cellular Respiration

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 cellular respiration?

Back

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

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (C6H12O6) and oxygen (O2).

Front

What are the main products of cellular respiration?

Back

The main products of cellular respiration are energy (ATP), carbon dioxide (CO2), and water (H2O).

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 + energy (ATP).

Front

What is the role of chlorophyll in photosynthesis?

Back

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

Front

What is aerobic respiration?

Back

Aerobic respiration is a type of cellular respiration that requires oxygen to produce energy from glucose.

Front

What is anaerobic respiration?

Back

Anaerobic respiration is a type of cellular respiration that occurs without oxygen, producing energy and byproducts like lactic acid or ethanol.

Front

What is lactic acid and when is it produced?

Back

Lactic acid is a byproduct of anaerobic respiration in muscles when oxygen is scarce, often causing muscle fatigue.
