6 Key Differences Between Antigen and Pathogen Explained

March 18, 2024April 23, 2024 - by Jaishree Gorane - Leave a Comment

Antigens and pathogens are crucial in understanding infectious diseases and the immune response. Antigens are substances that provoke an immune response, potentially leading to antibody production. In contrast, pathogens are organisms or agents that cause diseases. The distinctions include their nature, composition, sources, roles, interactions with the immune system, and types, shedding light on their unique functions in health and disease.

8 Key Differences Between Antigens and Antibodies

March 18, 2024March 18, 2024 - by Jaishree Gorane - Leave a Comment

Antigens and antibodies differ in several aspects. Antigens, like bacteria or viruses, trigger immune responses and can originate from within the body in autoimmune diseases. Antibodies, produced in response to antigens, neutralise or eliminate them, aiding in immunity. They vary in molecular structure, origin, and function etc..

What is Interstitial Fluid and its Vital Role in Cellular Health and Function

February 9, 2024February 9, 2024 - by Jaishree Gorane - Leave a Comment

Interstitial fluid, also known as tissue fluid, occupies the spaces between body cells, acting as a crucial part of extracellular fluid. Originating from blood plasma through capillary filtration, it provides essential nutrients and oxygen to cells while removing wastes. Its composition, similar to plasma but with fewer proteins, supports various physiological processes, including nutrient transport and waste removal.

The Pancreas – Structure, Function and Hormonal Secretions

June 30, 2023June 30, 2023 - by Jaishree Gorane - Leave a Comment

The pancreas is a glandular organ located in the abdominal cavity. It has a complex structure consisting of various parts, including the head, body, and tail. Functionally, the pancreas plays a crucial role in both the digestive and endocrine systems. It produces and secretes digestive enzymes and juices, essential for the breakdown and absorption of nutrients. Additionally, the pancreas secretes important hormones like insulin and glucagon, which regulate blood sugar levels. The pancreatic structure, function, and hormonal secretions are vital for maintaining overall health and metabolic balance.

Difference Between Pollination and Fertilisation

June 25, 2023December 23, 2023 - by Jaishree Gorane - Leave a Comment

Understanding the difference between pollination and fertilisation is crucial in plant reproduction. Pollination is the transfer of pollen from the stamen to the pistil, whereas fertilisation is the fusion of male and female gametes to form a zygote. Pollination occurs before fertilisation and can lead to genetic variation. These processes play an important role in the successful reproduction of plants.

Difference Between Chemosynthesis and Photosynthesis

June 23, 2023December 23, 2023 - by Jaishree Gorane - Leave a Comment

Chemosynthesis and photosynthesis are two different processes with different energy sources and reactions. While photosynthesis uses light energy, carbon dioxide and water to produce glucose and oxygen, chemosynthesis relies on chemical energy from inorganic compounds and produces organic compounds without the involvement of light or oxygen.

Photorespiration occurs in

June 10, 2023June 10, 2023 - by Jaishree Gorane - Leave a Comment

Photorespiration occurs in C3 plants and involves several organelles. In chloroplasts, RuBP oxygenase reacts with RuBP, leading to the formation of PGA and PGly. Glycolic acid is produced in chloroplasts and then undergoes oxidation in peroxisomes, forming glyoxylic acid. Within mitochondria, glycine combines with CO2 and NH3, releasing CO2 and forming serine.

Photorespiration is a Wasteful process Justify

June 10, 2023June 10, 2023 - by Jaishree Gorane - Leave a Comment

Photorespiration is a wasteful process that inhibits photosynthesis by diverting RuBisCO activity from carbon fixation. It reduces the production of glucose and oxygen, important products of photosynthesis. In addition, photorespiration consumes ATP instead of producing it, resulting in a loss of energy for the plant. It also leads to a loss of fixed carbon through the release of carbon dioxide, which further reduces carbon gain.

Crassulacean Acid Metabolism (CAM) -Pathway, Significance, Examples

June 10, 2023June 10, 2023 - by Jaishree Gorane - Leave a Comment

Crassulacean Acid Metabolism (CAM) is a specialised form of photosynthesis in xerophytic succulents. CAM Plants absorb CO2 at night, store it as malic acid and release it during the day for carbohydrate production. They conserve water by closing the stomata during the day. Examples are orchids, cacti, aloe and pineapple. CAM enables efficient CO2 use, water conservation and reduced photorespiration in arid environments.
