FAQs on 4 Days Study Plan: Respiration in Plants - Biology Class 11 - NEET

1. What is the Krebs cycle and why is it important in respiration?
Ans. The Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions that occur in the mitochondria of cells. It plays a crucial role in cellular respiration, which is the process by which cells generate energy from glucose. During the Krebs cycle, acetyl-CoA molecules are oxidized and broken down, producing carbon dioxide, ATP (adenosine triphosphate), and reducing agents such as NADH and FADH2. These reducing agents then go on to participate in the electron transport chain, leading to the production of more ATP. The Krebs cycle is essential for the efficient production of energy in the form of ATP.
2. What are shuttle systems in respiration and how do they contribute to ATP synthesis?
Ans. Shuttle systems in respiration refer to the mechanisms by which reducing agents, such as NADH, generated during glycolysis in the cytoplasm, are transported into the mitochondria for further ATP synthesis. There are two main shuttle systems: the malate-aspartate shuttle and the glycerol 3-phosphate shuttle. In the malate-aspartate shuttle, NADH is converted into malate in the cytoplasm and then transported into the mitochondria, where it is converted back into NADH. This NADH can then participate in the electron transport chain, leading to ATP synthesis. In the glycerol 3-phosphate shuttle, NADH is converted into glycerol 3-phosphate in the cytoplasm and then transported into the mitochondria. Inside the mitochondria, glycerol 3-phosphate is converted back into NADH, which can then enter the electron transport chain and contribute to ATP synthesis. Both shuttle systems play a crucial role in maximizing ATP production by efficiently transporting reducing agents into the mitochondria.
3. What is the chemiosmotic hypothesis and how does it explain ATP synthesis during respiration?
Ans. The chemiosmotic hypothesis, proposed by Peter D. Mitchell, explains how ATP synthesis occurs during respiration. According to this hypothesis, ATP synthesis is coupled to the flow of protons (H+) across the inner mitochondrial membrane. During respiration, the electron transport chain pumps protons from the mitochondrial matrix to the intermembrane space, creating an electrochemical gradient. This gradient represents a higher concentration of protons in the intermembrane space compared to the mitochondrial matrix. The chemiosmotic hypothesis suggests that the flow of protons back into the mitochondrial matrix through ATP synthase, an enzyme complex located in the inner mitochondrial membrane, drives the synthesis of ATP. As protons pass through ATP synthase, their energy is used to phosphorylate ADP (adenosine diphosphate), forming ATP. In summary, the chemiosmotic hypothesis proposes that the flow of protons across the inner mitochondrial membrane powers ATP synthesis during respiration.
4. What is fermentation and how does it differ from respiration?
Ans. Fermentation is an anaerobic process that occurs in the absence of oxygen and involves the partial breakdown of glucose to generate energy. It is a metabolic pathway used by cells when oxygen is limited or unavailable. During fermentation, glucose is converted into either lactic acid or ethanol, depending on the organism. The process does not involve the complete oxidation of glucose and does not utilize the electron transport chain or the Krebs cycle. Instead, it relies on the glycolysis pathway to generate a small amount of ATP. In contrast, respiration is an aerobic process that occurs in the presence of oxygen. It involves the complete oxidation of glucose to produce energy in the form of ATP. Respiration includes glycolysis, the Krebs cycle, and the electron transport chain, which collectively generate a much larger amount of ATP compared to fermentation. The main difference between fermentation and respiration is the presence or absence of oxygen and the amount of ATP produced. Respiration is more efficient and produces a higher yield of ATP, while fermentation is a less efficient process that only produces a small amount of ATP.
5. How do enzymes play a role in respiration?
Ans. Enzymes play a crucial role in respiration by facilitating the various chemical reactions involved in the breakdown of glucose and the synthesis of ATP. They act as catalysts, speeding up the rate of these reactions without being consumed in the process. During respiration, several enzymes are involved in different stages of the metabolic pathways. For example, enzymes such as hexokinase and phosphofructokinase catalyze specific steps in the glycolysis pathway, while enzymes such as citrate synthase and isocitrate dehydrogenase are involved in the Krebs cycle. Enzymes lower the activation energy required for a reaction to occur, allowing the reactions to proceed at a faster rate. They achieve this by binding to specific substrates, forming an enzyme-substrate complex. This complex undergoes chemical reactions, leading to the formation of products. Once the reaction is complete, the enzyme is released and can bind to another substrate. Without enzymes, the metabolic reactions in respiration would occur too slowly to sustain life. Enzymes ensure that the energy generation process is efficient and occurs at a suitable rate to meet the energy needs of the cell.
