Cellular Respiration and Photosynthesis Concepts

What is the primary energy currency used by cells?

• Glucose

• Adenosine Triphosphate

• Pyruvate

• Carbon Dioxide

Which of the following are the reactants (inputs) for aerobic cellular respiration?

• Carbon dioxide and water

• Glucose and oxygen

• ATP and water

• Pyruvate and oxygen

How do photosynthesis and cellular respiration relate to each other in terms of glucose?

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

• Both processes make glucose.

• Photosynthesis makes glucose, and cellular respiration breaks it down.

• Neither process involves glucose.

Which type of organism is capable of performing both photosynthesis and cellular respiration?

• Animals

• Fungi

• Plants

• Bacteria

Where does the process of glycolysis occur within a eukaryotic cell?

• Nucleus

• Mitochondria

• Cytoplasm

• Cell membrane

Which of the following are direct outputs of the Krebs cycle?

• Glucose and Oxygen

• Carbon dioxide, ATP, NADH, and FADH2

• Pyruvate and Acetyl CoA

• Water and Oxygen

What is the main function of FADH2 and NADH in cellular respiration?

• To directly produce glucose

• To store carbon dioxide

• To transfer electrons for ATP production

• To break down proteins

In eukaryotic cells, where does the electron transport chain and chemiosmosis primarily take place?

• Cytoplasm

• Outer mitochondrial membrane

• Inner mitochondrial membrane

• Nucleus

What is the role of ATP synthase in the electron transport chain?

• To pump electrons into the intermembrane space

• To break down glucose molecules

• To produce ATP by allowing protons to flow through it

• To combine oxygen with carbon dioxide

What is the estimated total net ATP molecules produced per glucose molecule during complete cellular respiration?

• 2 ATP

• 4 ATP

• 10-15 ATP

• 30-38 ATP
