What are some examples of metabolic waste?

They are ammonia, urea, uric acid, and creatinine. All of these substances are produced from protein metabolism. In many animals, the urine is the main route of excretion for such wastes; in some, the feces is.

What are metabolic wastes give examples?

Metabolic Wastes

Metabolic waste is the left over products of both catabolism and anabolism. This waste includes salts, phosphates, sulfates, excess substances, and nitrogenous wastes like urea which are eliminated through urine.

Is faeces a metabolic waste?

Humans must get rid of two types of wastes. Wastes from the digestive system (feces) and wastes from metabolic activities (sweat & urine). Removing digestive wastes (pooping) is called egestion. Removing metabolic wastes is called excretion.

What are the wastes produced during metabolic activities?


  • Carbon dioxide.
  • Water.
  • Ammonia.
  • Urea.
  • Uric acid.
  • Bile pigment.
  • Excess salts.


Which of the following is a metabolic waste product?

Complete answer: Urea, ammonia and creatinine are metabolic waste products in protein metabolism. ‘Metabolic wastes’ also called ‘excrements’, are substances that are formed as by-products in the metabolic processes. These cannot be utilised by the organism and when accumulated in surplus can be toxic.

What do you mean by metabolic waste?

Metabolic wastes or excretes are substances left over from metabolic processes, which cannot be used by the organism (they are surplus or have lethal effect), and must therefore be excreted. This includes nitrogen compounds, water, CO2, phosphates, sulphates, indoles, medicals, food additives etc.

What is the removal of metabolic wastes called?

These are known as metabolism. These chemical reactions produce waste products such as carbon dioxide, water, salts, urea and uric acid. … The excretory organs remove these wastes. This process of removal of metabolic waste from the body is known as excretion.

How does the body get rid of metabolic waste?

All the metabolic wastes are excreted in a form of water solutes through the excretory organs (nephridia, Malpighian tubules, kidneys), with the exception of CO2, which is excreted together with the water vapor throughout the lungs. The elimination of these compounds enables the chemical homeostasis of the organism.

Is water a metabolic waste?

Metabolic wastes (carbon dioxide, water, oxygen, and nitrogenous compounds) diffuse through the cell membranes of these unicellular organisms into the outside environment.

Why is feces not a metabolic waste?

Why are feces not metabolic waste? The bulk of dried feces is dead bacteria and cells from the gut plus any fiber or other indigestible matter. You can produce feces without eating. Metabolic waste chemically speaking usually refers to the “exhaust “ of metabolizing sugars fats and proteins.

Is creatinine a metabolic waste?

Urea and creatinine are waste products produced during protein metabolism. Both of these waste products are carried to the kidney and filtered into the urine. They are measured to evaluate how well the kidney is working. In the United States, urea is called “B.U.N.”, or, Blood Urea Nitrogen.

What gas is considered a metabolic waste product of cellular metabolism?

During the process of cellular respiration, carbon dioxide is given off as a waste product.

How do cells excrete waste?

Scientists propose that the cell may pile all the unwanted proteins together in a glob called an aggregate to keep them from gumming up normal cellular machinery. … If the garbage can’t be digested by lysosomes, the cell can sometimes spit it out in a process called exocytosis.

What is the most common metabolic waste product?

Selected Answer: stomach Question 9 3 out of 3 points The most common metabolic waste product is ____. Selected Answer: carbon dioxide Question 10 3 out of 3 points The enzyme that digests fats is ____.

How do kidneys remove metabolic waste?

The kidneys remove waste products called urea from the blood through tiny filtering units called nephrons. There are about one million nephrons in each kidney. Each nephron consists of a ball formed of small blood capillaries, called a glomerulus, and a small tube called a renal tubule.

Is electrolytes a metabolic waste product?

The main substances excreted in urine are: metabolic waste products – e.g., urea and creatinine. electrolytes – inorganic compounds (including sodium, potassium, calcium, chloride and bicarbonate) that your body uses to control the fluid content inside your body fluids.
