Cellular Respiration and ATP Concepts

What does ATP stand for?

• Adenosine Triphosphate

• Adenine Triphosphate

• Adenosine Diphosphate

• Adenine Diphosphate

What type of macromolecule is ATP?

• Carbohydrate

• Lipid

• Protein

• Nucleic Acid

Which organelle is primarily involved in aerobic cellular respiration in eukaryotic cells?

• Nucleus

• Mitochondria

• Ribosome

• Endoplasmic Reticulum

What are the primary reactants (inputs) for aerobic cellular respiration?

• Carbon dioxide and water

• Glucose and oxygen

• ATP and water

• Pyruvate and oxygen

How do the overall equations for cellular respiration and photosynthesis relate to each other?

• They are identical

• The reactants of one are the products of the other

• They share no common molecules

• Photosynthesis only produces ATP, while cellular respiration only produces glucose

What is the primary role of glucose in cellular respiration?

• It is a waste product

• It acts as an enzyme

• It is broken down to produce ATP

• It is used to build proteins

Where does glycolysis take place and what is its oxygen requirement?

• Mitochondria; aerobic

• Cytoplasm; anaerobic

• Nucleus; aerobic

• Cytoplasm; aerobic

After glycolysis, what happens to pyruvate in the intermediate step of aerobic cellular respiration?

• It is converted into glucose

• It is transported into the nucleus

• It is converted to acetyl CoA in the mitochondrial matrix

• It is immediately used to produce large amounts of ATP

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

• Glucose, Oxygen, Water

• Carbon dioxide, ATP, NADH, FADH2

• Pyruvate, Acetyl CoA, ATP

• Lactic acid, Ethanol, ATP

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

• To directly produce glucose

• To act as structural components of the cell membrane

• To transfer electrons to the electron transport chain

• To break down ATP into ADP
