What the Respiration in Plants Exemplar Covers

The Exemplar tests the same chapter as the textbook but at a higher level of difficulty. Its questions probe common traps in glycolysis, fermentation, the Krebs cycle and the electron transport system. Because Chapter 12 is heavy on step-wise pathways and ATP accounting, the Exemplar spends its questions checking whether students can track carbon through each pathway, tell aerobic from anaerobic respiration, and work out the net ATP yield from the respiratory balance sheet.

• Glycolysis, its site in the cytoplasm, and the two routes of fermentation (alcoholic and lactic acid).
• Aerobic respiration, the Krebs cycle (TCA cycle) and the electron transport system with oxidative phosphorylation.
• The respiratory balance sheet, the amphibolic pathway, and the respiratory quotient (RQ) for different substrates.

Why Practise the Exemplar for This Chapter

The Exemplar bridges the gap between the NCERT textbook and the level of a competitive exam. For respiration, its questions are close to the style asked in NEET and CUET, where a single detail about the site of the Krebs cycle or the net ATP from one glucose can decide a mark. Because Chapter 12 is built on ordered steps and numbers, the Exemplar is where students find the tricky assertion-reason sets and the well-framed MCQs that a plain reading of the textbook rarely throws up.

• Higher-order questions that the textbook exercises do not cover.
• Assertion-reason sets that sharpen your grip on glycolysis and the Krebs cycle.
• MCQs on ATP yield and the electron transport system at exam level.

How to Use the Exemplar for Respiration in Plants

Attempt the Exemplar only after you have finished the NCERT textbook chapter and its back exercises. Treat it as your second, harder pass over the chapter. Because much of this chapter is a chain of reactions with an ATP count, students gain the most by writing out each pathway with its site and yield rather than only marking the option, so the balance sheet stays fixed in memory for the exam.

• Solve the MCQs first to test recall, then move to assertion-reason.
• Attempt each short and long answer fully before checking the Exemplar Solutions.
• Mark the questions you got wrong and redo them after two days.
• Keep a flow chart of glycolysis, the Krebs cycle and the ETS handy while you practise.

Other Class 11 Biology Respiration in Plants Resources

Use the Exemplar with the textbook PDF, the solved answers, the revision notes and the formula sheet for the same chapter. Working across all the resources gives students the definitions, the practice and the higher-order questions they need for both the CBSE board exam and NEET.

Student Feedback on the Respiration in Plants Exemplar

More than 10,000 Class 11 students used these Collegedunia NCERT resources during the 2026 boards and NEET preparation. Their feedback shaped how we present this chapter, and the message on Chapter 12 was consistent: the Exemplar is what turns a step-heavy pathway chapter into exam-ready recall.

• Students rated the assertion-reason sets as the most useful part for fixing the respiratory pathways.
• Many said the Exemplar MCQs on ATP yield matched the NEET questions they later saw.
• Students preparing for CUET found the short-answer terms a fast way to revise the whole chapter.
