Bioenergetics: Photosynthesis & Cellular Respiration

Front

What is ATP and its role in cellular processes?

Back

ATP (Adenosine Triphosphate) is the primary energy carrier in cells, providing energy for various cellular functions such as movement, synthesis, and transport.

Front

How does ATP provide energy for cellular activities?

Back

ATP releases energy when its terminal phosphate bond is broken, converting it to ADP (Adenosine Diphosphate) and an inorganic phosphate.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis converts light energy into chemical energy stored in glucose, while cellular respiration breaks down glucose to release energy stored in ATP.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What are the main reactants of cellular respiration?

Back

The main reactants of cellular respiration are glucose and oxygen.

Front

What is the significance of the light-dependent reactions in photosynthesis?

Back

Light-dependent reactions capture solar energy and convert it into chemical energy in the form of ATP and NADPH.

Front

What is the significance of the Calvin cycle in photosynthesis?

Back

The Calvin cycle uses ATP and NADPH from the light-dependent reactions to convert carbon dioxide into glucose.

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP.

Front

What is glycolysis and where does it occur?

Back

Glycolysis is the first step of cellular respiration that breaks down glucose into pyruvate, occurring in the cytoplasm.

Front

What is the Krebs cycle and where does it occur?

Back

The Krebs cycle, also known as the citric acid cycle, occurs in the mitochondria and processes pyruvate to produce ATP, NADH, and FADH2.
