Cellular Resp. & Mighty Mito.

What does ATP stand for and what is its role in cells?

• Adenosine di phosphate, stores energy

• Adenosine di phosphate, transfers electrons

• Adenosine tri phosphate, stores energy

• Adenosine tri phosphate, transfers electrons

Which molecule is the starting point for glycolysis?

• Pyruvate

• Glucose

• ATP

• NADH

What is the significance of mitochondria in cellular respiration?

• They synthesize glucose

• They store ATP

• They produce oxygen

• They are the site of the Krebs cycle and electron transport chain

Where does the Krebs Cycle occur within the cell?

• Ribosome

• Cytoplasm

• Mitochondria

• Nucleus

What is the final electron acceptor in the electron transport chain?

• Glucose

• Water

• Carbon dioxide

• Oxygen

What is produced as a waste product during cellular respiration?

• ATP and NADH

• Glucose and oxygen

• Carbon dioxide and water

• Oxygen and ATP

What role does ATP synthase play in the electron transport chain?

• Synthesizes ATP

• Breaks down glucose

• Transfers electrons

• Produces carbon dioxide

How does fermentation differ from aerobic respiration?

• It produces more ATP

• It does not require oxygen

• It occurs in the mitochondria

• It requires oxygen

Which process occurs when oxygen is not available in the cell?

• Krebs Cycle

• Electron Transport Chain

• Glycolysis

• Fermentation

What is the impact of cyanide on cellular respiration?

• It enhances ATP production

• It blocks a step in the electron transport chain

• It increases oxygen uptake

• It initiates fermentation
