Q: What is metabolism?
- The process of photosynthesis in plants
- The sum of all biochemical reactions in a living organism
- The breakdown of glucose only
- The synthesis of proteins only
A: The sum of all biochemical reactions in a living organism

Q: Where does glycolysis occur within a cell?
- In the mitochondria
- In the nucleus
- In the cytoplasm
- In the endoplasmic reticulum
A: In the cytoplasm

Q: How many ATP molecules are generated during glycolysis?
- Four ATP molecules
- Two ATP molecules
- Six ATP molecules
- Eight ATP molecules
A: Two ATP molecules

Q: Why is fermentation important for glycolysis?
- It produces additional ATP
- It regenerates NAD+ to allow glycolysis to continue
- It converts glucose into oxygen
- It occurs only in aerobic conditions
A: It regenerates NAD+ to allow glycolysis to continue

Q: Which metabolic pathway breaks down molecules to release energy?
- Anabolism
- Glycolysis
- Catabolism
- Fermentation
A: Catabolism

Q: What is the primary role of the citric acid cycle?
- To produce glucose
- To generate ATP from carbohydrates, fats, and proteins
- To synthesize amino acids
- To convert pyruvate into lactic acid
A: To generate ATP from carbohydrates, fats, and proteins

Q: How does the presence of oxygen affect the metabolic processes in cells?
- It decreases the rate of glycolysis
- It allows for aerobic respiration to occur
- It has no effect on metabolism
- It only affects protein synthesis
A: It allows for aerobic respiration to occur

Q: Which of the following statements about NADH is true?
- It is produced only during fermentation
- It is an electron carrier involved in redox reactions
- It is not involved in glycolysis
- It is produced exclusively in the mitochondria
A: It is an electron carrier involved in redox reactions

Q: In what phase of glycolysis are ATP molecules consumed?
- Energy payoff phase
- Energy investment phase
- Fermentation phase
- Citric acid cycle phase
A: Energy investment phase

Q: How can understanding metabolic pathways help in addressing metabolic disorders?
- By ignoring the role of enzymes
- By linking metabolic pathways to environmental changes
- By providing insights into the biochemical basis of diseases
- By focusing solely on aerobic respiration
A: By providing insights into the biochemical basis of diseases
