How does the process of decarboxylation of amino acids contribute to the overall metabolism of proteins in living organisms?
Decarboxylation of amino acids is a chemical reaction that removes a carbon dioxide molecule from the amino acid structure. This process is important in protein metabolism because it helps in the breakdown of amino acids for energy production and the synthesis of other molecules needed for various cellular functions.

How cells the same chemically?
Cells are the building blocks of all living organisms and share basic chemical components such as DNA, RNA, proteins, lipids, and carbohydrates. These components contribute to the common molecular processes necessary for life, including metabolism, growth, and reproduction, making cells chemically similar.
What are the molecular basis of living organisms?
The molecular basis of living organisms lies in the complex interactions of biomolecules such as DNA, RNA, proteins, and lipids. These molecules work together to carry out essential functions such as growth, reproduction, and metabolism. The information encoded in DNA is transcribed into RNA, which is then translated into proteins that carry out specific tasks within the cell.
These compounds are used to carry out chemicals and regulate metabolism in organisms?
Enzymes are the compounds used in organisms to carry out chemical reactions and regulate metabolism. They act as biological catalysts to speed up reactions, allowing essential processes to occur efficiently within cells.
Why must nitrogen cycle through an ecosystem?
Nitrogen is essential for the growth and survival of living organisms, as it is a key component of proteins and DNA. The nitrogen cycle facilitates the conversion of nitrogen between different forms that can be utilized by organisms in the ecosystem. This cycling process ensures that nitrogen is continuously available for plants and other organisms to support their growth and metabolism.
Formation of phenylethylamine and carbon dioxide?
Phenylethylamine can be formed by the decarboxylation of phenylalanine, an amino acid found in proteins. This reaction involves the removal of a carboxyl group (-COOH) to form phenylethylamine and carbon dioxide. The decarboxylation of phenylalanine occurs in the presence of specific enzymes, such as aromatic L-amino acid decarboxylase.
What is protein metabolism called?
protein metabolism is the metabolism of proteins
Why are proteins important in biology and how do they contribute to the functioning of living organisms?
Proteins are essential in biology because they play crucial roles in the structure, function, and regulation of cells and tissues in living organisms. They contribute to the functioning of organisms by serving as enzymes that catalyze chemical reactions, as structural components in cells and tissues, as transporters of molecules, and as signaling molecules that regulate various processes in the body. Overall, proteins are vital for the growth, development, and maintenance of living organisms.
What is the relationship between basal energy metabolism and protein metabolism?
Basal energy metabolism refers to the energy needed to maintain essential bodily functions at rest, while protein metabolism involves the breakdown and synthesis of proteins in the body. Proteins play a role in basal metabolism as they contribute to the energy expenditure required for maintaining vital processes such as muscle function and organ maintenance. Moreover, proteins are involved in the repair and growth of tissues, which can impact the overall energy expenditure of an individual.
Do proteins have calories and how do they contribute to overall calorie intake?
Yes, proteins contain calories. Each gram of protein provides 4 calories. Proteins contribute to overall calorie intake by providing energy for the body's functions, such as metabolism and muscle repair. Consuming protein-rich foods can help maintain a balanced diet and support overall health.

What do ammonia urea and enzymes have in common?
Ammonia, urea, and enzymes are all involved in biological processes. Ammonia and urea are nitrogenous waste products produced during the breakdown of proteins, while enzymes are proteins that catalyze chemical reactions in living organisms. Enzymes can be involved in the metabolism of ammonia and urea to regulate nitrogen metabolism in the body.
Which macromolecule provides the most nitrogen for organisms?
Proteins provide the most nitrogen for organisms. Proteins are composed of amino acids, and nitrogen is a key component of amino acids. During protein metabolism, nitrogen is utilized by organisms for various biological processes, including growth and repair.
How do organisams get proteins?
Organisms can synthesize proteins or get them in their diet.
How is energy released by fats and carbohydrates and proteins?
metabolism
If a cell makes mainly protein is it a multicellular or single-celled organism?
If a cell mainly produces proteins, it could be part of a multicellular organism. In multicellular organisms, different cells specialize in producing specific proteins that contribute to the overall functioning of the organism. Single-celled organisms are capable of producing proteins but may have a more general cellular function.
