 17.Demonstrate the three reactions that result in substrate level phosphorylation during cellular respiration.

answer:

  1. During glycolysis, four molecules of ATP are generated from one molecule of glucose, and two molecules of ATP are formed in two Krebs cycles through substrate-level phosphorylation.
  2. The phosphate group is transported straight from a substrate to ADP, resulting in ATP.
  3. The following are some of them:
    1. When 1,3-diphosphoglycerate is converted to 3-phosphoglycerate, 2 ATP is produced.
    2. When 2-phosphoenol pyruvic acid converts to pyruvic acid, 2 ATP is produced. When succinyl CoA is converted to succinate, two ATP molecules are produced in two Krebs cycles.
    3. GTP is formed by converting GDP to GTP, which subsequently transfers phosphate to ADP to produce ATP.

Final answer: 6 ATP are formed through substrate-level phosphorylation from one molecule of glucose when it is completely oxidized.

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 ...

  11.Explain the relationship between electron transport and oxidative phosphorylation. What does ATP synthase look like, and how does it work? answer:  How is electron transport couple to oxidative phosphorylation? Reactions of the electron transport chain take place in the inner mitochondria membrane, and production of ATP in the mitochondria comes from oxidative phosphorylation [ADP is phosphorylated to give ATP] Proton gradient is created by the pumping of electrons and represents stored potential energy, and provides basis for a coupling mechanism.      “Oxidative phosphorylation is the process of ATP formation, when electrons are transferred by electron carriers from NADH or FADH2 to oxygen” What is Oxidative Phosphorylation? Oxidative phosphorylation is the final step in cellular respiration. It occurs in the mitochondria. It is linked to a process known as electron transport chain. The electron transport system is located in the inner mitochondrial membr...

  12.Discuss the different kinds of interactions that stabilize the tertiary structures of proteins.   answers: Protein is made up of polypeptide chains that are the polymers of amino acids. It is a biomolecule. Protein exists in primary, secondary, tertiary and quaternary structures. The tertiary structure is the three-dimensional structure. It is found in a globular protein. When linear protein is coiled and makes loops it is called tertiary structure. It becomes round. The bonds that provide stabilisation to the tertiary structure of the protein are disulphide bonds, ionic bonds and hydrophobic bonds and wander Waal's interactions. Myoglobin is an example of the tertiary structure of the protein.
