AP Biology Mid-Term Practice

Front

What is the main job of the electron carriers in cellular respiration?

Back

Transport electrons and hydrogen atoms to the electron transport chain.

Front

What phase involves sister chromatids aligning on the plate in the middle of the cell?

Back

Metaphase.

Front

Which process is the largest contributor to the release of CO2?

Back

Citric Acid Cycle or Krebs Cycle.

Front

When is oxygen gas produced in photosynthesis?

Back

When the water molecule is split.

Front

What is the process called when glucose is broken down into pyruvate?

Back

Glycolysis.

Front

What is the role of ATP in cellular processes?

Back

ATP serves as the primary energy currency of the cell.

Front

Define cellular respiration.

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

What are the three main stages of cellular respiration?

Back

Glycolysis, Krebs Cycle, and Oxidative Phosphorylation.

Front

What is chemiosmosis?

Back

Chemiosmosis is the movement of ions across a selectively permeable membrane, down their electrochemical gradient, which is used to generate ATP.

Front

What is the function of NAD+ in cellular respiration?

Back

NAD+ acts as an electron carrier, accepting electrons during glycolysis and the Krebs cycle.
