Respiration — Class 11 Bio-Botany (Samacheer Kalvi)
TN State Board (Samacheer Kalvi) Class 11 Bio-Botany, Chapter 14. Glycolysis, Krebs cycle and electron transport chain.
1. About this chapter
This chapter covers Respiration as part of the Class 11 Samacheer Kalvi Bio-Botany curriculum. It deals with glycolysis, krebs cycle and electron transport chain and builds conceptual understanding essential for the TN HSC Public Exam.
By the end of this chapter, students will be able to:
- Trace the steps of glycolysis
- Calculate ATP yield from aerobic respiration
2. Key concepts
- Concept 1: Trace the steps of glycolysis.
- Concept 2: Calculate ATP yield from aerobic respiration.
3. Important terms and formulas
| Term / Formula | Description |
|---|---|
| Trace the steps of… | Trace the steps of glycolysis |
| Calculate ATP yield from… | Calculate ATP yield from aerobic respiration |
4. Worked examples
Example 1. Applying a key concept from this chapter.
Solution: Identify the relevant principle → apply the formula or rule → state the answer with correct units.
Example 2. A typical exam-style question on respiration.
Solution: Break the problem into steps, use the appropriate formula and verify the answer.
5. Common mistakes
- Mistake: Skipping units or forgetting to state them. Fix: Always write units alongside every quantity and answer.
- Mistake: Confusing similar terms or concepts in this chapter. Fix: Make a comparison table of the terms during revision.
6. Practice (exam-style)
- Define the main term or principle covered in Chapter 14.
- Give two real-life examples related to respiration.
- Solve a short numerical or descriptive question from this chapter.
- State one important formula and explain each symbol.
7. Answer key (hints)
- Refer to section 2 (Key concepts) above for the definition.
- Examples should be drawn from daily experience and local context.
- Apply the formula from section 3, show all steps clearly.
- Formula with units — refer to the textbook glossary for symbol meanings.
8. Quick revision
- Class 11 Bio-Botany — Chapter 14: Respiration.
- Core idea: Glycolysis, Krebs cycle and electron transport chain.
- Key outcomes: Trace the steps of glycolysis; Calculate ATP yield from aerobic respiration.
- Always revise diagrams / tables from the Samacheer Kalvi textbook before the exam.
