Cellular Respiration, Photosynthesis, and ATP

Front

What is ATP?

Back

ATP (Adenosine Triphosphate) is a molecule that carries energy within cells, consisting of adenine, ribose, and three phosphate groups.

Front

What is the primary function of ATP in cellular processes?

Back

The primary function of ATP is to store and transfer energy for various cellular activities, including muscle contraction, nerve impulse propagation, and biosynthesis.

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 stages of cellular respiration?

Back

The main stages of cellular respiration are Glycolysis, the Krebs Cycle (Citric Acid Cycle), and the Electron Transport Chain.

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 pigment found in chloroplasts that absorbs sunlight, providing the energy needed for photosynthesis.

Front

What is the equation for photosynthesis?

Back

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

Front

What is the ultimate source of energy for living organisms?

Back

The ultimate source of energy for living organisms is the Sun.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

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

Front

What do all living organisms perform?

Back

All living organisms perform cellular respiration to generate energy.
