Unit 3 Review

Front

What is the output of the Calvin cycle?

Back

G3P (Glyceraldehyde-3-phosphate) is the primary output of the Calvin cycle.

Front

Which step of cellular respiration requires oxygen?

Back

Oxidative phosphorylation is the step of cellular respiration that requires oxygen.

Front

What is the final electron acceptor in cellular respiration?

Back

Oxygen is the final electron acceptor in cellular respiration.

Front

What happens to the absorbance of DCPIP when placed 90 cm from a light source?

Back

The change in absorbance over time in the solution will be less than that of the other samples.

Front

How many turns of the Calvin cycle are needed to synthesize 1 G3P?

Back

3 turns of the Calvin cycle are required to synthesize 1 G3P.

Front

Define the Calvin cycle.

Back

The Calvin cycle is a series of biochemical reactions that take place in the chloroplasts of photosynthetic organisms, converting carbon dioxide and other compounds into glucose.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the final stage of cellular respiration where ATP is produced using energy derived from the electron transport chain.

Front

Explain the role of NADPH in photosynthesis.

Back

NADPH provides the reducing power for the Calvin cycle, helping to convert carbon dioxide into glucose.

Front

What is glycolysis?

Back

Glycolysis is the first step of cellular respiration that breaks down glucose into pyruvate, producing a small amount of ATP.

Front

What is the Krebs cycle?

Back

The Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetate derived from carbohydrates, fats, and proteins.
