What are the main stages of respiration in plants?

The main stages of aerobic respiration in plants are (1) Glycolysis, which occurs in the cytoplasm, (2) Pyruvate oxidation, which links glycolysis to the Krebs cycle, (3) The Krebs cycle (Citric Acid Cycle), occurring in the mitochondrial matrix, and (4) Oxidative phosphorylation (Electron Transport Chain and Chemiosmosis), taking place on the inner mitochondrial membrane.

How is respiration in plants different from animals?

Plants can produce their own glucose through photosynthesis, meaning they don't need to 'eat' in the same way animals do to obtain respiratory substrates. Also, gas exchange in plants occurs through stomata and lenticels, whereas animals typically have specialized respiratory organs.

What is the net gain of ATP from one molecule of glucose during complete aerobic respiration?

During complete aerobic respiration, the theoretical maximum yield of ATP from one molecule of glucose is around 30-32 molecules of ATP, although the actual yield can vary.

What is the role of ATP in respiration?

ATP (Adenosine Triphosphate) is the primary energy currency of the cell. The energy released during the oxidation of glucose is captured and stored in the high-energy phosphate bonds of ATP, which is then used to power various cellular processes.

Where does glycolysis occur in plant cells?

Glycolysis, the initial breakdown of glucose into pyruvate, occurs in the cytoplasm of plant cells.

What is the significance of the Krebs cycle?

The Krebs cycle is central to cellular respiration. It completely oxidizes acetyl-CoA, generating ATP (or GTP), and crucial electron carriers (NADH and FADH2) that fuel the electron transport chain for massive ATP production.

How does anaerobic respiration differ from aerobic respiration in plants?

Anaerobic respiration occurs in the absence of oxygen and yields much less ATP compared to aerobic respiration. Glycolysis is common to both, but in anaerobic respiration, pyruvate undergoes fermentation (e.g., alcoholic fermentation producing ethanol and CO2) instead of entering the Krebs cycle.

Are these MCQs relevant for NEET 2026?

Yes, these MCQs are specifically designed to align with the NEET 2026 syllabus for Biology, covering the 'Respiration in Plants' chapter thoroughly to aid your preparation.
