In plants enzymes are present in -a)Only in flowersb)Onlly in leavesc)All the living cells of plant bodyd)Only in parenchymaCorrect answer is option 'C'. Can you explain this answer?

Question

Answer

Enzymes are Protenicious substances that are capable of Catalysing chemical reactions of biological system . they are Biocatalysts. so the correct option is (c). we can not say that enzymes present in particular regions.

Answer

Four plant enzyme groups exist: Proteases - break long protein chains into smaller amino acid chains and eventually into single amino acids. Amylases - reduce polysaccharides to disaccharides: lactose, maltose, and sucrose..It affects all the parts of plant and thus present in all living cell of plant body.

Answer

Enzymes are biological molecules that catalyze or speed up chemical reactions in living organisms. They play a crucial role in various cellular processes, including metabolism, growth, and development. In plants, enzymes are present in all living cells of the plant body. Let's explore this further.

Enzymes in Plants

Enzymes are essential for plant growth and development. They are involved in various physiological processes, such as photosynthesis, respiration, and nutrient absorption. Plants produce a wide range of enzymes to carry out these different functions. Some of the major types of enzymes found in plants include:

1. Photosynthetic Enzymes: These enzymes are involved in the process of photosynthesis, where plants convert sunlight into chemical energy. Examples of photosynthetic enzymes include Rubisco (ribulose-1,5-bisphosphate carboxylase/oxygenase) and ATP synthase.

2. Respiratory Enzymes: These enzymes are responsible for the breakdown of organic molecules to release energy during respiration. Enzymes like cytochrome oxidase and succinate dehydrogenase are involved in the respiratory chain.

3. Digestive Enzymes: Plants produce enzymes to break down complex molecules into simpler forms for absorption. For example, amylase breaks down starch into glucose, while proteases break down proteins into amino acids.

4. Defense Enzymes: Plants produce enzymes to protect themselves against pathogens and pests. For instance, chitinases break down chitin, a major component of fungal cell walls, while protease inhibitors inhibit the activity of proteases produced by insects.

Distribution of Enzymes in Plants

Enzymes are present in all living cells of the plant body. This includes not only the leaves but also other plant organs, such as stems, roots, flowers, and fruits. Every cell in a plant contains specific enzymes that are required for its metabolic activities. The distribution of enzymes in plants is not limited to specific tissues or organs but is widespread throughout the plant body.

For example, in leaves, enzymes involved in photosynthesis, such as Rubisco, are present in chloroplasts. In roots, enzymes responsible for nutrient uptake, such as phosphatases and nitrate reductases, are found in the root hairs and epidermal cells. Similarly, enzymes involved in various metabolic pathways are distributed in different tissues and cells based on their specific functions.

Conclusion

In conclusion, enzymes are present in all living cells of the plant body. They are involved in various physiological processes and are crucial for plant growth and development. Enzymes in plants are not limited to specific organs or tissues but are distributed throughout the plant body. Understanding the distribution and functions of enzymes in plants is essential for studying plant physiology and developing strategies for improving crop productivity.
