The correct Answer is:
To solve the question regarding why RBCs (Red Blood Cells) and adipose tissue cells respire anaerobically, we will analyze each option provided in the question step by step. ### Step 1: Understanding Anaerobic Respiration Anaerobic respiration occurs in the absence of oxygen. Certain cells, like RBCs and adipose tissue cells, can perform this type of respiration to meet their energy needs. ### Step 2: Analyzing the Options 1. **Possess very few mitochondria**: - RBCs lack mitochondria entirely, which means they cannot perform aerobic respiration. Adipose tissue cells have fewer mitochondria compared to other cells, which limits their ability to carry out aerobic respiration. Therefore, this option is correct. 2. **Require much less energy**: - While it is true that RBCs do not require as much energy as muscle cells, adipose tissue cells still require a significant amount of energy for their functions, such as storing fat. Thus, this option is not entirely accurate. 3. **Possess very few mitochondria and a large amount of energy**: - This statement is contradictory. If cells possess very few mitochondria, they cannot produce a large amount of energy through aerobic respiration. Therefore, this option is incorrect. 4. **Possess carbonic anhydrase**: - Carbonic anhydrase is an enzyme present in RBCs that helps in the transport of carbon dioxide. However, it is not relevant to the anaerobic respiration of adipose tissue cells, as they do not possess this enzyme. Thus, this option is incorrect. ### Conclusion Based on the analysis: - The correct answer is **(1) Possess very few mitochondria**. This is the primary reason why RBCs and adipose tissue cells respire anaerobically.

Make corrections wherever you find mistake in spellings/words in the following paragraphs :- A. When fats are used in respiration, the RQ is more than unity because fats contain more O_(2) and require relatively less amount of O_(2) for oxidation. B. The most important energy carrier is ATP. This energy rich compound is mobile and can pass from one cell into another. C. Before pyruvic acid enters Krebs cycle, one of the two carbon atoms of pyruvic acid is reduced to carbon dioxide in the reaction called reductive carboxylation. The remaining two carbon pyruvate unit is accepted by coenzyme A to form acetyl coenzyme A.

Study carefully the following statements and select the incorrect ones. When fats are used in respiration, the RQ is more than unity because fats contain more O_(2) and require relatively less amount of O_(2) for oxidation. (ii) The most important energy carrier is ATP. This energy rich compound is mobile and can pass from one cell to another. (iii) Before pyruvic acid enter Krebs' cycle, one of the two carbon atoms of pyruvic acid is reduced to carbon dioxide in the reaction called reductive carboxylation. (iv) A special electron carrier system located in the mitochondrial membrane is called shuttle system. It transfers electron from the hydrogens of cytoplasmic NADH to the mitochondrial electron carriers across the mitochondrial membrane. (v) Zymase is a complex mixture of many enzymes which requires several coenzymes for its action. The enzyme complex-zymase catalyses series of reaction taking place during fermentation leading to the production of ethyl alcohol.

Read the given passage carefully and answer the questions that follow. Certain words are printed in bold to help you locate them while answering some of these. Renewable Energy (RE) is the future. With that said, one can argue that the future has arrived, in parts at least. Worldwide acceptance towards green energy is giving the sustainable energy sector more market share every year. The growth is consistent, with each year out-performing the previous, leading renewable energy to account for 1/3rd of global energy capacity. It’s fair to state that the growth trajectory is incredible, and considering that it took only a little more than a just decade to reach this position, we could call it _____________. However, the most important question is, is this satisfactory? The goal of green energy transition is to solve growing energy scarcity and reduce dependency on fossil fuels in order to move towards a fully sustainable energy landscape. Therefore, to identify success, we need to compare renewable energy growth with the current scenario. According to WHO’s estimates, currently, more than 7 million people die every year from pollution, up from 4.2 million in 2016. Fossil fuel consumption has increased globally from 94,462/twh in 2000 to 1,33,853/twh now. The rise in population (currently 7.7 billion) indicates a steady growth in energy demand worldwide. In comparison, the fact that renewable energy took a decade to become 1/3 of energy capacity is not the ideal pace, considering we might not have two more decades to wait for RE to catch up. Which of the following is NOT true with respect to the context of the passage? I. Deaths due to increased pollution level have escalated in the past few years. II. Though the rate of growth in RE is less than required, it has been consistent. III. More market share allotment to green energy has given RE a worldwide acceptance.
