Comparing Photosynthesis and Cellular Respiration

What is the primary goal of photosynthesis?

• To produce water

• To store energy

• To consume carbon dioxide

• To release energy for immediate use

Which molecule is considered a rechargeable energy source in biology?

• Carbon dioxide

• ATP

• Oxygen

• Glucose

What is the main purpose of cellular respiration?

• To produce oxygen

• To consume ATP

• To store energy

• To release stored energy

Where does cellular respiration primarily take place?

• In the chloroplasts

• In the cytoplasm and mitochondria

• On the cell membrane

• In the nucleus

What is the role of ATP synthase?

• To reattach phosphate to ADP, creating ATP

• To transport protons across membranes

• To create a gradient for chemiosmosis

• To break down glucose molecules

What is chemiosmosis a process in?

• Neither photosynthesis nor cellular respiration

• Both photosynthesis and cellular respiration

• Only cellular respiration

• Only photosynthesis

What is happening to the carbon in glucose/pyruvate that enters the Krebs Cycle?

• It is released as carbon dioxide

• It is stored as glucose

• It is stored as carbon dioxide

• It is released as glucose

What acts as the final electron acceptor in cellular respiration?

• water

• carbon dioxide

• glucose

• oxygen

What are the products of the light-dependent reactions in photosynthesis?

• Oxygen and glucose

• ATP, NADPH, and oxygen

• Carbon dioxide and ATP

• Glucose and water

Which of the following is not a product of the Krebs cycle?

• Glucose

• FADH2

• NADH

• ATP
