The main nitrogenous waste in the human body is [A] Urea. Urea is formed in the liver during the breakdown of proteins and amino acids in a process called deamination. Ammonia, a highly toxic compound, is initially produced from the deamination process, but the liver converts it into urea, which is less toxic and more soluble in water. Urea is then transported through the bloodstream to the kidneys, where it is filtered out of the blood and excreted in urine. Uric acid, on the other hand, is a waste product of purine metabolism and is excreted by the kidneys in small amounts. Ammonium nitrate is not a naturally occurring waste product in the human body but rather a chemical compound used in fertilizers.
The end product of anoxic respiration is [C] Lactic acid. Anoxic respiration, also known as anaerobic respiration, occurs in the absence of oxygen. In this process, pyruvic acid, produced during glycolysis, is converted into lactic acid through fermentation. This reaction helps to regenerate NAD+ frRead more
The end product of anoxic respiration is [C] Lactic acid. Anoxic respiration, also known as anaerobic respiration, occurs in the absence of oxygen. In this process, pyruvic acid, produced during glycolysis, is converted into lactic acid through fermentation. This reaction helps to regenerate NAD+ from NADH, allowing glycolysis to continue in the absence of oxygen. Lactic acid fermentation is common in certain microorganisms and in human muscle cells during intense exercise when oxygen supply is limited. Unlike aerobic respiration, which produces carbon dioxide and water as end products, anoxic respiration leads to the accumulation of lactic acid. Lactic acid can contribute to muscle fatigue and soreness but can also be utilized as a source of energy by certain organisms and tissues under anaerobic conditions.
In the Krebs cycle, [D] Fumaric acid is synthesized. The Krebs cycle, also known as the citric acid cycle, is a central metabolic pathway occurring in the mitochondria. It begins with the condensation of acetyl-CoA and oxaloacetate to form citrate. Through a series of enzyme-catalyzed reactions, citRead more
In the Krebs cycle, [D] Fumaric acid is synthesized. The Krebs cycle, also known as the citric acid cycle, is a central metabolic pathway occurring in the mitochondria. It begins with the condensation of acetyl-CoA and oxaloacetate to form citrate. Through a series of enzyme-catalyzed reactions, citrate is sequentially converted into various intermediate compounds, including fumaric acid. These reactions involve oxidation-reduction reactions and substrate-level phosphorylation, ultimately leading to the regeneration of oxaloacetate to sustain the cycle.
The Krebs cycle plays a crucial role in cellular respiration, serving as a source of high-energy electrons used to generate ATP through oxidative phosphorylation. While pyruvic acid is a product of glycolysis, and lactic acid can be formed during anaerobic conditions, glucose is not synthesized during the Krebs cycle.
The approximate amount of CO2 in our exhaled air is [D] 16%. Exhaled air contains a higher concentration of carbon dioxide compared to inhaled air because CO2 is a waste product of cellular respiration. While inhaled air typically contains about 0.04% CO2, exhaled air can have concentrations rangingRead more
The approximate amount of CO2 in our exhaled air is [D] 16%. Exhaled air contains a higher concentration of carbon dioxide compared to inhaled air because CO2 is a waste product of cellular respiration. While inhaled air typically contains about 0.04% CO2, exhaled air can have concentrations ranging from 3-5%, depending on factors such as metabolism, respiratory rate, and environmental conditions. During cellular respiration, cells use oxygen and glucose to produce energy, releasing CO2 as a byproduct. This CO2 is transported via the bloodstream to the lungs, where it diffuses into the alveoli and is then exhaled during expiration. The higher concentration of CO2 in exhaled air reflects the metabolic activity occurring within the body and provides a means for the removal of this waste gas from the bloodstream.
The complete conversion of sucrose into CO2 and water in the presence of oxygen with the release of energy is called [A] Aerobic respiration. Aerobic respiration is a cellular process that occurs in the presence of oxygen, involving the breakdown of organic molecules such as sucrose (a disaccharide)Read more
The complete conversion of sucrose into CO2 and water in the presence of oxygen with the release of energy is called [A] Aerobic respiration. Aerobic respiration is a cellular process that occurs in the presence of oxygen, involving the breakdown of organic molecules such as sucrose (a disaccharide) into carbon dioxide (CO2) and water (H2O) while releasing energy in the form of ATP (adenosine triphosphate).
This process consists of multiple stages, including glycolysis, the Krebs cycle (also known as the citric acid cycle), and oxidative phosphorylation, which occurs in the mitochondria. Aerobic respiration is highly efficient, producing a large amount of ATP per molecule of sucrose compared to anaerobic respiration. It is the primary energy-generating process in most eukaryotic cells, providing the necessary energy for cellular functions and metabolic activities.
