Sample MCQs from the Collection
Ch 3 Which organelle is known as the "powerhouse of the cell"?
Correct Answer: B) Mitochondria
Explanation: Mitochondria are called the "powerhouse of the cell" because they produce ATP (adenosine triphosphate) through cellular respiration, which provides energy for various cellular activities.
Ch 8 In photosynthesis, which gas is released as a byproduct?
Correct Answer: C) Oxygen
Explanation: During photosynthesis, plants use carbon dioxide and water to produce glucose and oxygen. The oxygen is released into the atmosphere as a byproduct.
Ch 7 What is the optimum pH for most enzymes in the human body?
Correct Answer: B) pH 7-8
Explanation: Most enzymes in the human body function optimally at neutral or slightly alkaline pH (7-8), which matches the pH of most body fluids. However, some enzymes like pepsin in the stomach work best at acidic pH (1.5-2).
📚 Study Tips for Biology MCQs
1. Understand Diagrams
Biology MCQs often include diagrams. Practice labeling and understanding biological structures.
2. Learn Terminology
Master biological terms and their definitions. Many MCQs test specific terminology.
3. Process Understanding
Focus on understanding biological processes (photosynthesis, respiration, etc.) rather than memorization.
4. Practice Regularly
Consistent practice with MCQs improves speed, accuracy, and concept retention.
