    An enzyme is fundamentally Protein. Enzymes are specialized proteins that catalyze biochemical reactions within living organisms. They function by lowering the activation energy required for a reaction to occur, thereby speeding up the rate of the reaction without being consumed in the process.

    Enzymes are highly specific, each catalyzing a particular chemical reaction or group of reactions. They achieve this specificity through their unique three-dimensional structure, which is determined by their amino acid sequence. This structure includes an active site where the substrate, the molecule upon which the enzyme acts, binds, facilitating the catalytic process.

    Enzymes play crucial roles in various physiological processes, including digestion, metabolism, DNA replication, and cellular signaling. Without enzymes, these processes would occur too slowly to sustain life. While enzymes are predominantly proteins, some RNA molecules, known as ribozymes, also exhibit catalytic activity.

    The component considered a protein is (a) Body builder. Proteins serve as the primary building blocks for tissues, including muscle tissue. They provide structural support and contribute to muscle growth, repair, and maintenance, making them indispensable for individuals, such as bodybuilders, aiming to increase muscle mass and strength.

    Proteins also serve various other functions beyond tissue building, including energy production (b), regulatory roles (c), and serving as enzymes, hormones, and antibodies. However, their role as bodybuilders primarily emphasizes their function in tissue formation and repair.

    While energy producers (b), regulatory molecules (c), and bulk enhancers (d) are essential for various physiological processes within the body, they are not classified as proteins. Instead, they may include carbohydrates, fats, vitamins, minerals, and other molecules that serve specific roles in energy metabolism, regulation, and overall health.

    Tissues formed in the body primarily consist of (a) Protein. Proteins are essential macromolecules that serve as the structural foundation for tissues throughout the body. They contribute to the formation of muscles, bones, skin, organs, and other vital structures.
    Proteins within tissues provide structural integrity, support, and functionality to maintain the overall architecture and function of organs and systems. Examples include collagen and elastin in connective tissues, actin and myosin in muscle tissues, and keratin in skin and hair.

    While fats (b), carbohydrates (c), and vitamins (d) play important roles in various physiological processes within the body, they do not serve as the primary structural components of tissues. Instead, they are involved in energy metabolism, cell signaling, and other essential functions that support tissue formation and overall health.

  4. To synthesize proteins 20 amino acids are essential. These amino acids are categorized into two groups: essential amino acids, which cannot be produced by the body and must be obtained through the diet, and non-essential amino acids, which the body can synthesize.

    To synthesize proteins 20 amino acids are essential. These amino acids are categorized into two groups: essential amino acids, which cannot be produced by the body and must be obtained through the diet, and non-essential amino acids, which the body can synthesize.

    The 20 amino acids crucial for protein synthesis include alanine, arginine, asparagine, aspartic acid, cysteine, glutamine, glutamic acid, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, and valine.

    During protein synthesis, these amino acids are linked together through peptide bonds in a specific sequence dictated by the genetic code. The unique sequence of amino acids determines the structure and function of the resulting protein, allowing for a vast array of proteins with diverse roles in biological processes such as enzyme catalysis, cellular signaling, and structural support.

    Blood glucose level is typically expressed in (b) mg per deciliter. This unit of measurement indicates the concentration of glucose present in a deciliter (100 milliliters) of blood. It is the standard unit used in clinical practice and self-monitoring of blood sugar levels.

    Maintaining blood glucose within a normal range is crucial for overall health, as fluctuations can lead to various health complications, including diabetes. Monitoring blood glucose levels is essential for individuals with diabetes to manage their condition effectively and prevent complications.

    Other units of measurement, such as grams per liter (d) and parts per million (c), are less commonly used for expressing blood glucose levels. mm of Hg (millimeters of mercury) (a) typically refers to blood pressure measurement, not blood glucose concentration.
