The substance responsible for accelerating chemical reactions in biological systems is (c) Enzymes. Enzymes are specialized proteins that function as biological catalysts, enhancing the rate of biochemical reactions without being consumed in the process.
Enzymes achieve this by lowering the activation energy required for a reaction to occur, thereby facilitating the formation of the transition state and speeding up the reaction. This acceleration is crucial for maintaining the multitude of biochemical processes necessary for life, including metabolism, digestion, cellular respiration, and DNA replication.
Unlike chemical catalysts, which are often specific to a particular reaction, enzymes exhibit high specificity for their substrates, the molecules upon which they act. This specificity is due to the unique three-dimensional structure of enzymes, which includes an active site where the substrate binds and undergoes catalysis.
Overall, enzymes play essential roles in maintaining cellular function and homeostasis, enabling organisms to carry out vital biochemical processes efficiently.

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.

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.

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.

The sensation of fatigue in muscles after prolonged strenuous physical work is primarily caused by (d) Accumulation of lactic acid. During intense exercise, when oxygen demand exceeds supply, the body resorts to anaerobic metabolism, breaking down glucose without oxygen. This process produces lactic acid as a byproduct, leading to an increase in acidity within the muscles.
The buildup of lactic acid contributes to muscle fatigue and discomfort, resulting in a burning sensation and reduced muscle function. However, it’s important to note that fatigue can also be influenced by other factors such as depletion of glycogen stores, minor muscle fiber damage, and central nervous system fatigue.
While decreased oxygen supply (a) can contribute to fatigue in prolonged exercise, it’s primarily the buildup of lactic acid that causes the acute sensation of muscle fatigue during intense physical activity.

Carbohydrates give an athlete more energy quickly. Unlike fats, which are metabolized slowly, and proteins and vitamins, which do not directly provide energy, carbohydrates are efficiently converted into glucose during digestion. This glucose serves as the primary fuel for muscles during high-intensity exercise.
Carbohydrates offer rapid energy replenishment, making them ideal for athletes needing quick bursts of energy for performance. Additionally, carbohydrates can be stored in the body as glycogen in the muscles and liver, providing a readily available energy reserve for prolonged physical activity.
While fats and proteins play essential roles in the body, such as providing long-term energy storage and supporting muscle repair and growth, respectively, carbohydrates are the preferred source of energy for immediate fuel needs, particularly during intense exercise or athletic competition.

Carbohydrates are stored in the human body in the form of Glycogen. Glycogen is a complex polysaccharide and serves as the primary storage form of glucose in animals, including humans. It is stored primarily in the liver and muscles.
When excess glucose is present in the bloodstream, particularly after consuming a meal high in carbohydrates, insulin signals cells to absorb glucose for energy production or storage. Some of this glucose is converted into glycogen through a process called glycogenesis. Glycogen serves as a readily accessible energy reserve that can be quickly broken down into glucose when blood sugar levels drop, such as during fasting or physical activity.
This glycogen storage system helps regulate blood sugar levels and ensures a steady supply of glucose to meet the body’s energy demands, particularly during periods of increased activity or when dietary carbohydrates are not available.
