The smallest endocrine gland in the human body is the [C] Pituitary gland. Despite its small size, the pituitary gland, also known as the master gland, plays a vital role in regulating numerous physiological processes. It is located at the base of the brain, nestled within a bony structure called the sella turcica. Despite its small size, the pituitary gland exerts significant control over the endocrine system by secreting various hormones that regulate growth, reproduction, metabolism, stress response, and other essential functions.
The pituitary gland consists of two main parts: the anterior pituitary (adenohypophysis) and the posterior pituitary (neurohypophysis), each responsible for producing distinct hormones. Despite its diminutive size compared to other endocrine glands like the thyroid or pancreas, the pituitary gland’s regulatory functions are indispensable for maintaining homeostasis and overall health.

Mammals make urea in the [A] Liver. Urea synthesis primarily occurs in the liver as a result of the deamination of amino acids during protein metabolism. The liver contains enzymes necessary for this process, converting ammonia, a toxic byproduct of protein breakdown, into urea, a less toxic compound. Once synthesized, urea is released into the bloodstream and transported to the kidneys for excretion. In the kidneys, urea is filtered out of the blood and excreted in urine, contributing to the body’s waste removal process.
The spleen is primarily involved in immune function and does not play a direct role in urea synthesis. The bladder, often colloquially referred to as a “bag,” is an organ involved in urine storage and does not produce urea but rather temporarily stores urine before elimination from the body.
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.

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.
