Metabolism

Front

What is metabolism?

Back

Metabolism is the set of life-sustaining chemical reactions in organisms that convert food into energy and building blocks for growth.

Front

What are autotrophs?

Back

Autotrophs are organisms that produce their own food from inorganic substances, typically through photosynthesis or chemosynthesis.

Front

What are heterotrophs?

Back

Heterotrophs are organisms that cannot produce their own food and must consume other organisms for energy.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells break down glucose and other organic molecules to produce ATP, the energy currency of the cell.

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 the role of chlorophyll in photosynthesis?

Back

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

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is the equation for cellular respiration?

Back

The equation for cellular respiration is C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP.

Front

How are photosynthesis and cellular respiration interconnected?

Back

Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce ATP, while cellular respiration releases carbon dioxide and water, which are used in photosynthesis.

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged among the biosphere, geosphere, hydrosphere, and atmosphere, involving processes like photosynthesis and respiration.
