A vertebrate is an animal with either a spinal column or a backbone.
Of the three pathways for obtaining ATP for muscle contraction , the aerobic respiration requires oxygen .
<h3>
What is respiration ?</h3>
Respiration is a biochemical process as well as a catabolic process by which food molecules are oxidised to liberate chemical energy in a step-wise process .Respiration is an energy liberating process . the energy released due to the process is temporarily stored as chemical energy in the form of ATP molecules.
Respiration are of two types ,these are aerobic respiration and anaerobic respiration .
Aerobic respiration :when food is oxidised using molecular oxygen is called aerobic respiration .38 molecules of ATP is available in the process. it occurs in both cytoplasm and mitochondria . food molecule is completely oxidised and carbon dioxide is released as by-product. example : in most of plants and animals .
Anaerobic respiration : when food is oxidised without using molecular oxygen called anaerobic respiration . 2 molecules of ATP is available in the process .it occurs in the cytoplasm .example : bacteria , yeast , mammalian RBC ,muscle tissue .
ATP: Adenosine triphosphate is called the energy currency of the cell . it is a organic compound composed of the phosphate groups ,adenine and the sugar ribose .the molecules provides energy for various biochemical processes in the body . therefore , it is called the energy currency of the cell .
