AP Bio Cellular Respiration and Photosynthesis

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is a series of biochemical reactions that take place in the stroma of chloroplasts in photosynthetic organisms, where carbon dioxide is converted into glucose using ATP and NADPH.

Front

What is the role of RuBisCo in photosynthesis?

Back

RuBisCo (Ribulose bisphosphate carboxylase/oxygenase) is the enzyme that catalyzes the first step of the Calvin Cycle, facilitating the fixation of carbon dioxide.

Front

What are the main products of the Krebs Cycle?

Back

The main products of the Krebs Cycle are ATP, NADH, FADH2, and carbon dioxide.

Front

Where does cellular respiration occur in eukaryotic cells?

Back

Cellular respiration occurs in the mitochondria of eukaryotic cells.

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, often resulting in byproducts like lactic acid or ethanol.

Front

What is the significance of ATP in cellular processes?

Back

ATP (adenosine triphosphate) is the primary energy carrier in cells, providing energy for various biochemical reactions.

Front

What is lactic acid fermentation?

Back

Lactic acid fermentation is an anaerobic process where glucose is converted into lactic acid and ATP, commonly occurring in muscle cells during strenuous exercise.

Front

What is the role of NADPH in photosynthesis?

Back

NADPH is a reducing agent that provides the electrons needed for the reduction of carbon dioxide in the Calvin Cycle.

Front

What is the function of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment found in chloroplasts that absorbs light energy, primarily from the sun, which is essential for the photosynthesis process.

Front

What is the overall equation for photosynthesis?

Back

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