  9. Discuss the discovery of ATP synthase complex and its role in high-energy molecule production.

answers:

ATP synthase is a complex enzyme that catalyzes the synthesis of ATP from ADP and inorganic phosphate. It was first discovered by Paul D. Boyer and John E. Walker in the late 1960s and early 1970s. They were awarded the Nobel Prize in Chemistry in 1997 for their work.

ATP synthase is found in the inner membrane of mitochondria in eukaryotic cells and in the plasma membrane of prokaryotic cells. It consists of two main parts: the F0 complex, which is embedded in the membrane and acts as a proton channel, and the F1 complex, which sits on top of the F0 complex and contains the enzymes that catalyze the actual synthesis of ATP.

ATP synthase works by using the energy from the flow of protons across the inner membrane to drive the rotation of a ring of subunits within the F1 complex. This rotation causes the subunits within the F1 complex to change conformation and catalyze the synthesis of ATP from ADP and inorganic phosphate.

ATP synthase is an important part of the process of cellular respiration, which generates the majority of the ATP used to fuel the metabolic reactions of cells. It is also the final enzyme in the process of photophosphorylation in photosynthetic organisms, which converts light energy into chemical energy in the form of ATP.

  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 classified based o

  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. Amylose

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
