 8.Oxidation of the 10 molecules of NADH produced from each glucose therefore accounts for almost 80 percent of the total energy released from the sugar. What does the ETC do with all this energy? 

answer :

Introduction: The metabolism of glucose is a complex process that involves a series of chemical reactions that convert the sugar into energy that can be used by cells. One of the key steps in this process is the oxidation of NADH, a molecule that is generated as a byproduct of glucose metabolism. This oxidation generates a significant amount of energy, which is then used to power other cellular processes.

Content: During the breakdown of one glucose molecule, it produces 2 molecules of NADH. The oxidation of these 10 NADH molecules, which occurs in the electron transport chain (ETC) of the mitochondria, accounts for nearly 80% of the total energy released from the sugar. The ETC is a series of protein complexes that transport electrons from NADH to oxygen, generating a proton gradient across the mitochondrial membrane. This proton gradient is then used to generate ATP through a process called chemiosmosis. In this process, an enzyme complex known as ATP synthase uses the energy of the proton gradient to drive the synthesis of ATP from ADP and inorganic phosphate.

Conclusion: In summary, the oxidation of NADH in the ETC is a crucial step in glucose metabolism as it generates a significant amount of energy that is used to power various cellular processes, most importantly the production of ATP through the process of chemiosmosis. Thus, the ETC plays a vital role in the energy metabolism of the cell.

  5. Tabulate the unique and common features for both plant and animal cells.  answer : Difference Between Plant cell and Animal cell The cell is the fundamental unit of life. All the life activities are carried out by cells. The organisms can be classified based on the number of cells present in them. Unicellular organisms are single-celled, while multicellular organisms have a large number of cells. Unicellular organisms are believed to be one of the earliest forms of life on earth. Eventually, more complex multicellular organisms evolved from these unicellular life forms over the aeons. Multicellular organisms have specialized cells with complicated cell organelles, which unicellular organisms typically lack. In an ecosystem, plants have the role of producers, while animals have taken the role of consumers. Hence, their daily activities and functions vary, and so does their cell structure. Cell structure and organelles vary in plants and animals, and are primarily clas...

  2.Compare the functions of starch and glycogen with a note about their different linkages. answers:  Difference between Starch, and Glycogen The table below shows the main differences between starch, cellulose and glycogen. Starch Glycogen It is a polymer of 𝜶-glucose subunits It is a polymer of 𝜶-glucose subunits It contains two types of polymers, amylose (unbranched and coiled) and amylopectin (branched) It is highly branched and similar to amylopectin The 𝜶-glucose subunits are joined by 1,4 glycosidic bonds in amylose and 1,4 and 1,6 glycosidic bonds in amylopectin The 𝜶-glucose subunits are joined by 1,4 and 1,6 glycosidic bonds Amylose is unbranched and amylopectin is branched It is highly branched It is the main storage carbohydrate in plants It is the main storage carbohydrate in animals and fungi Structure of Starch Starch is the main storage carbohydrate of plants. It is made up of 𝜶-glucose subunits. It contains two types of polymers, amylose and amylopectin....

1. Elaborate on the diversity of the root and shoot system of plants answer: Introduction Plants are one of the most important living organisms on earth. They have huge benefits for both humans and animals. A plant is made up of numerous parts. Distinct parts serve different purposes. The shoot system refers to the portion of the plant that protrudes above ground level, whereas the root system refers to the portion buried beneath the soil. The essential parts of a plant are: Roots Stem Leaves Flowers Fruits The study of plant organ tissue and cellular structure is known as plant anatomy. Cells serve as the fundamental building block of plants. Cells are organised into tissues, which are then organised into organs. Plant organs differ from one another in terms of their internal structure. The monocots and dicots are also observed to have diverse anatomical structures within angiosperms. Internal structures also exhibit environmental adaptations. Anatomy of Root All vascular plants have ...
