Full Notes and Biology Question Papers for Class 11 are Available on the Extramarks App

The Living World is an important chapter that students can learn from Class 11 Biology Sample Paper provided by the Extramarks app. By learning the 11th Biology Question Paper, students will learn that Inorganic compounds contain water, minerals, etc. and are always micro biomolecules while organic molecules can be micro or macromolecules. Such two types of biomolecules play significant metabolism roles: Water forms 70-90 percent of the cellular reservoir. This shapes 65 percent of the human body (about two-thirds). In the ratio of 2:1, it is composed of H, and O. Ninety-five percent of water is stored in the free state and five percent in cell combined form. Water helps to support the processes of life. So water is called elixir or lip crib, as life in the absence of water is unlikely. Oxygen is primarily used to generate energy-rich ATP molecules in the aerobic cell respiration of the nutrients inside the mitochondria, so it is essential for life. Just 5 percent of the available energy is released in the absence of oxygen. Sodium chloride (common salt) role: Sodium chloride plays an important role in the body's metabolic functions, especially when it is in ionic form. Carbohydrates are organic compounds usually formed in a ratio of 1:2:1 by C, H, and O. Such carbohydrates are commonly referred to as saccharides as the main storage molecules, and most organisms use carbohydrates as essential fuel, breaking those bonds and releasing energy to sustain life.
