Exploring Cellular Respiration Concepts

What is the primary function of ATP in the body?

• To store genetic information

• To provide energy for cellular processes

• To act as a structural component of cells

• To transport oxygen in the blood

Which organelle is primarily responsible for generating ATP?

• Chloroplast

• Mitochondria

• Ribosome

• Nucleus

What type of process is the breakdown of complex molecules to release energy?

• Anabolic

• Photosynthetic

• Catabolic

• Fermentative

In cellular respiration, where do the high-energy electrons come from?

• Sunlight

• Water

• Breakdown of food

• ATP

What is the high-energy bond in an ATP molecule?

• The bond between ribose and the first phosphate

• The bond between the second and third phosphates

• The bond between adenine and ribose

• The bond between the first and second phosphates

What is substrate-level phosphorylation?

• Adding a phosphate to ADP using an enzyme and a substrate

• Adding a phosphate to ADP using a proton gradient

• Using light energy to add a phosphate to ADP

• Removing a phosphate from ATP

What is the main difference between photosynthesis and cellular respiration?

• Photosynthesis occurs in mitochondria, while cellular respiration occurs in chloroplasts

• Photosynthesis is an anabolic process, while cellular respiration is catabolic

• Photosynthesis uses oxygen, while cellular respiration produces oxygen

• Photosynthesis releases energy, while cellular respiration stores energy

Where does glycolysis occur in the cell?

• Chloroplast

• Cytoplasm

• Nucleus

• Mitochondria

What is the net gain of ATP molecules from glycolysis?

• 2 ATP

• 4 ATP

• 6 ATP

• 8 ATP

Which enzyme is responsible for adding a phosphate to glucose during glycolysis?

• Phosphoglycerate kinase

• Phosphofructokinase

• Hexokinase

• Triose phosphate dehydrogenase
