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.

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.
The nutrient that provides maximum energy is Carbohydrate. Carbohydrates are the body's primary source of energy, providing 4 calories per gram. They are efficiently converted into glucose during digestion, which is then utilized by cells for energy production through cellular respiration. While proRead more
The nutrient that provides maximum energy is Carbohydrate. Carbohydrates are the body’s primary source of energy, providing 4 calories per gram. They are efficiently converted into glucose during digestion, which is then utilized by cells for energy production through cellular respiration.
While proteins and fats also provide energy, carbohydrates are the preferred and most rapidly metabolized energy source. Protein provides 4 calories per gram, but its primary role is in building and repairing tissues rather than serving as an energy source. Fats provide the most concentrated energy, with 9 calories per gram, but they are metabolized more slowly compared to carbohydrates.
Vitamins and mineral salts do not directly provide energy but play crucial roles in various physiological processes within the body, such as metabolism, immune function, and overall health. However, they do not serve as a direct source of energy like carbohydrates do.
Honey mainly contains Carbohydrate. It is primarily composed of natural sugars, predominantly glucose and fructose, with smaller amounts of other sugars such as sucrose and maltose. These sugars provide the sweet taste and energy content of honey. While honey is primarily known for its carbohydrateRead more
Honey mainly contains Carbohydrate. It is primarily composed of natural sugars, predominantly glucose and fructose, with smaller amounts of other sugars such as sucrose and maltose. These sugars provide the sweet taste and energy content of honey.
While honey is primarily known for its carbohydrate content, it also contains trace amounts of other nutrients such as enzymes, amino acids, vitamins, and minerals. However, these nutrients are present in relatively low concentrations compared to the carbohydrate content.
Honey’s nutritional composition can vary depending on factors such as floral source, processing methods, and storage conditions. Despite its carbohydrate-rich nature, honey is often valued not only for its sweet flavor but also for its potential health benefits, including antioxidant properties, wound healing effects, and soothing qualities for coughs and sore throats.
