In what step of cellular respiration is glucose broken down?

• Aerobic Respiration

• Krebs Cycle

• Electron Transport Chain

• Glycolysis

What is the term for an organism that makes its own source of chemical energy?

• Chloroplast

• Decomposer

• Producer

• Protist

_______ is an organelle found in plant cells where light absorption and photosynthesis take place.

What are the two main products of the Krebs Cycle?

• H₂O and CO₂

• ATP and CO₂

• ATP and O₂

• ADP and H₂O

Through photosynthesis, plants convert energy from sunlight into___________.

• light energy

• thermal energy

• chemical energy

• mechanical energy

______ is process that captures and transforms light energy from the sun and store it in high-energy sugar molecules

Which chemical equation best represents the process of photosynthesis?

• 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

• C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O

• C₆H₁₂O₆ + 6H₂O → C₆H₁₂O₆ + 6O₂

• 6CO₂ + O₂ → C₆H₁₂O₆ + 6O₂ + H₂O

_______ is an energy-carrying molecule that is used to store energy in a phosphate-phosphate bond during photosynthesis.

How would you describe cellular respiration?

• Sunlight and CO₂ make ATP

• ATP and O₂ are used to make sugars

• Carbon-based molecules from food and oxygen are used to make ATP

• ATP and CO₂ are used to make ADP and Water
