AP Bio Cellular Respiration and Photosynthesis

Front

What determines the fate of pyruvate?

Back

Oxygen is the key factor that determines whether pyruvate will undergo aerobic respiration (leading to the Krebs cycle) or anaerobic fermentation.

Front

Where does the Krebs cycle occur?

Back

The Krebs cycle occurs in the mitochondrial matrix of eukaryotic cells.

Front

What enzyme in the electron transport chain (ETC) is responsible for generating ATP molecules?

Back

ATP synthase is the enzyme that synthesizes ATP from ADP and inorganic phosphate during the electron transport chain.

Front

Where does the electron transport chain (ETC) occur?

Back

The electron transport chain occurs in the inner mitochondrial membrane.

Front

Which reactions in photosynthesis produce glucose?

Back

The Calvin cycle reactions are responsible for producing glucose during photosynthesis.

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, and the Electron Transport Chain.

Front

What is the role of NADH in cellular respiration?

Back

NADH acts as an electron carrier, transporting electrons to the electron transport chain for ATP production.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.

Front

What is the function of chlorophyll in photosynthesis?

Back

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