Cellular Respiration Concepts and Processes

What is the main purpose of ATP in cells?

• To store genetic information

• To provide energy for cell processes

• To build cell walls

• To transport oxygen

Which type of cells perform aerobic cellular respiration using mitochondria?

• Prokaryotic cells

• Eukaryotic cells

• Bacterial cells

• Viral cells

What are the two main inputs needed for aerobic cellular respiration?

• Carbon dioxide and water

• Glucose and oxygen

• Light and water

• ATP and carbon dioxide

How do photosynthesis and cellular respiration differ in their use of glucose?

• Photosynthesis breaks down glucose, while cellular respiration makes glucose.

• Photosynthesis makes glucose, while cellular respiration breaks down glucose.

• Both processes make glucose.

• Both processes break down glucose.

Where does the first step of cellular respiration, called glycolysis, occur in a cell?

• Inside the nucleus

• Inside the mitochondria

• Inside the cytoplasm

• Inside the cell wall

What are some of the outputs of the Krebs Cycle?

• Oxygen and water

• Carbon dioxide, ATP, NADH, and FADH2

• Glucose and oxygen

• Pyruvate and ATP

Where does the Electron Transport Chain and Chemiosmosis take place in eukaryotic cells?

• Outside the cell membrane

• In the cytoplasm

• Inside the inner mitochondrial membrane

• In the nucleus

What is the main job of ATP Synthase?

• To break down glucose

• To pump electrons

• To make ATP from ADP and phosphate

• To produce carbon dioxide

What molecule acts as the final electron acceptor in the Electron Transport Chain?

• Carbon dioxide

• Water

• Oxygen

• Glucose

What process allows cells to make ATP when oxygen is not available?

• Photosynthesis

• Fermentation

• Krebs Cycle

• Electron Transport Chain
