What is the process of cellular respiration and why is it important?
The building blocks of proteins are amino acids, which are small organic molecules. Amino acids are linked together by peptide bonds to form long chains called polypeptides. Many polypeptides join to form a protein. The sequence of amino acids in a protein is called its primary structure. Proteins aRead more

Amino acids are linked together by peptide bonds to form long chains called polypeptides. Many polypeptides join to form a protein. The sequence of amino acids in a protein is called its primary structure.
Proteins are important for many functions in the body, including:
Structural elements: Proteins provide many of the structural elements of a cell and help bind cells together into tissues
Chemical reactions: Proteins catalyze most of the chemical reactions that occur in a cell
Transport: Proteins transport nutrients
Hormones and enzymes: Proteins function as hormones and enzymes

Cellular respiration is a process that breaks down food molecules to produce energy for cells. It’s a vital process that occurs in the cells of all plants and some animals.
See lessWhat it is
Cellular respiration is a series of chemical reactions that occur in the mitochondria of cells.
It breaks down glucose and oxygen to produce energy in the form of adenosine triphosphate (ATP).
It also releases carbon dioxide and water as waste products.
Why it’s important
Cellular respiration provides cells with the energy they need to function.
Without cellular respiration, living things would not be able to get the energy they need from food and would eventually die.
How it works
Cellular respiration has three main stages: glycolysis, the citric acid cycle, and oxidative phosphorylation.
The reactions involved in cellular respiration are catabolic, meaning they break down molecules into smaller ones.
