Some One-Liners with Answers from Respiration in Plants Chapter
Q1: Where does glycolysis occur in a cell?
A: Glycolysis occurs in the cytoplasm of the cell.
Q2: What is the final product of glycolysis?
A: The final product of glycolysis is pyruvate (pyruvic acid).
Q3: Which organelle is known as the powerhouse of the cell?
A: Mitochondria is known as the powerhouse of the cell.
Q4: What is the net ATP gain in aerobic respiration?
A: The net ATP gain is 36-38 ATP molecules per glucose molecule.
Q5: What is the role of oxygen in aerobic respiration?
A: Oxygen acts as the final electron acceptor in the Electron Transport Chain (ETC).
Tables for Quick Revision
Comparison of Aerobic and Anaerobic Respiration
| Feature | Aerobic Respiration | Anaerobic Respiration |
|---|---|---|
| Oxygen Required | Yes | No |
| End Products | CO2 and H2O | Ethanol or Lactic Acid |
| Energy Produced (ATP) | 36-38 ATP | 2 ATP |
| Occurs in | Mitochondria | Cytoplasm |
Major Steps of Cellular Respiration
| Step | Location | Key Process |
|---|---|---|
| Glycolysis | Cytoplasm | Breakdown of glucose into pyruvate |
| Krebs Cycle | Mitochondria | Acetyl-CoA oxidation to release CO2 |
| ETC | Mitochondria | ATP production using oxygen |
FAQs on “Respiration in plants class 11 notes PDF download”
1. Why is respiration important in plants?
Respiration is essential in plants to break down glucose and release energy in the form of ATP, which is required for metabolic activities.
2. What is the difference between respiration and photosynthesis?
Respiration is a catabolic process that breaks down glucose to release energy, while photosynthesis is an anabolic process that synthesizes glucose using sunlight.
3. What happens if oxygen is not available for respiration?
In the absence of oxygen, plants undergo anaerobic respiration, leading to the production of ethanol or lactic acid with lesser ATP yield.
4. How can I memorize the Krebs Cycle easily?
Use mnemonics, flowcharts, and practice drawing the cycle multiple times to enhance memorization.
5. What is the significance of the respiratory quotient (RQ)?
RQ helps in determining the type of respiratory substrate used (carbohydrates, fats, or proteins) and gives insights into metabolic activities.
