Cell Energy & Cell Cycle

What is the role of cyclins and cyclin-dependent kinases (CDKs) in cell cycle regulation?

• Cyclins and CDKs regulate the cell cycle by controlling the timing and coordination of events.

• Cyclins and CDKs are responsible for DNA replication in the cell cycle.

• Cyclins and CDKs regulate the cell cycle by promoting cell division.

• Cyclins and CDKs are involved in cell differentiation during the cell cycle.

What are the consequences of cell cycle checkpoints malfunctioning in cancer cells?

• Normal cell division and controlled tumor formation.

• Increased cell death and reduced tumor growth.

• Uncontrolled cell division and tumor formation

• Decreased cell division and inhibited tumor growth.

What are the products of photosynthesis?

• water and carbon dioxide
• oxygen and glucose
• oxygen and carbon dioxide
• oxygen and water

What are the two reactants of cellular respiration?

• C₆H₁₂O₆ & 6CO₂
• 6 CO₂ & 6H₂O
• C₆H₁₂O₆ & 6O₂
• 6CO₂ & 6O₂

What is the correct equation for cellular respiration?

• 6O₂ + C₆H₁₂O₆ -> 6CO₂ + 6H₂O + Energy
• 6O₂ + C₆H₁₂O₆ + Energy -> 6CO₂ + 6H₂O
• 6CO₂ + 6H₂O -> 6O₂ + C₆H₁₂O₆ + Energy
• 6CO₂ + 6H₂O + Energy -> 6O₂ + C₆H₁₂O₆

The diagram below shows the relationship between photosynthesis and cellular respiration and the organelles in which they occur.Which statement describes how photosynthesis and cellular respiration are interrelated?

•  Oxygen is produced during cellular respiration and stored during photosynthesis.
• Carbon dioxide and water released by cellular respiration are used in photosynthesis.
• Photosynthesis releases the energy that is stored during the process of cellular respiration.
•  Glucose is used during cellular respiration to produce food that is broken down during photosynthesis.

The diagram shows the processes of photosynthesis and cellular respiration in relation to each other.  Which statement correctly describes the relationship between photosynthesis and cellular respiration? 

• The reactants and products of both processes are the same. 
• Photosynthesis and cellular respiration occur in all organisms. 
• Products of photosynthesis form the reactants for cellular respiration. 
• All ATP produced during photosynthesis is utilized during cellular respiration.
