 6.Name at least three amino acids whose side chains have the characteristic of being able to repel water and Define denaturation of proteins, is it fine to take denature proteins as food? Explain based on the classroom discussion we had.

answers:

The nine amino acids that have hydrophobic side chains are


glycine (Gly),

alanine (Ala)

, valine (Val),

leucine (Leu),

isoleucine (Ile),

proline (Pro),

phenylalanine (Phe),

methionine (Met),

and tryptophan (Trp).

. These side chains are composed mostly of carbon and hydrogen, have very small dipole moments,

Denaturation of proteins

Denaturation of proteins is an irreversible change in which proteins get precipitated when they are heated with alcohol, concentrated inorganic acids or by salts of heavy metals. Protein is uncoiled and its shape is destroyed. Characteristic biological activity is lost.
Examples include the following :
(i) Boiling of egg coagulates egg white.
(ii) Milk is converted to curd.


What happens if you eat denatured proteins?
You see, when we consume these denatured proteins, their molecules are broken down into individual amino acids that are then brought together in our cells to become a source of dietary protein




Is denatured protein less nutritious?

The denaturation changes only the structure of the protein molecules but does not affect their nutritional value

  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
