AP Biology Photosynthesis and Cellular Respiration

Front

What is glycolysis?

Back

Glycolysis is the metabolic process that breaks down glucose into pyruvate, producing a small amount of ATP and NADH in the process.

Front

What is the main purpose of the Krebs cycle?

Back

The main purpose of the Krebs cycle is to produce electron donors (NADH and FADH2) that are used in the electron transport chain to generate ATP.

Front

What molecule is released during the Krebs cycle?

Back

Carbon Dioxide (CO2) is released during the Krebs cycle as a byproduct of the conversion of acetyl CoA.

Front

List the stages of cellular respiration in order.

Back

The stages of cellular respiration in order are glycolysis, the citric acid cycle (Krebs cycle), and oxidative phosphorylation.

Front

Which molecule enters the Krebs cycle?

Back

Acetyl CoA enters the Krebs cycle after being produced from the breakdown of pyruvate.

Front

What is the role of ATP in cellular respiration?

Back

ATP serves as the primary energy currency of the cell, providing energy for various cellular processes.

Front

Define oxidative phosphorylation.

Back

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

Front

What are electron carriers in cellular respiration?

Back

Electron carriers, such as NADH and FADH2, transport electrons to the electron transport chain, facilitating ATP production.

Front

What is the significance of the electron transport chain?

Back

The electron transport chain is crucial for generating a large amount of ATP through the process of chemiosmosis.

Front

Explain 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.
