Photosynthesis and Cellular Respiration Flashcard

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, and releasing oxygen as a byproduct.

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 the chemical equation for photosynthesis?

Back

6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂

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, which is essential for photosynthesis.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs energy from its surroundings, usually in the form of heat.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases energy to its surroundings, usually in the form of heat.

Front

What is ATP and its role in cellular processes?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

Front

What happens to ATP during cellular respiration?

Back

During cellular respiration, ATP is produced from ADP and inorganic phosphate through the breakdown of glucose.

Front

What is the difference between anabolic and catabolic reactions?

Back

Anabolic reactions build larger molecules from smaller ones, while catabolic reactions break down larger molecules into smaller ones.
