Respiration Flashcards
What is respiration?
Respiration is a chemical reaction taking place in every cell where glucose is broken down to release energy.
What is the respiratory substrate?
Respiratory substrate is the substance broken down by respiration to release energy.
What is an exothermic reaction?
EXOTHERMIC REACTION means a chemical reaction that releases energy
What is aerobic respiration?
Aerobic respiration - reaction that releases energy from glucose. It uses oxygen and produces carbon dioxide.
What is anaerobic respiration
Anaerobic respiration - reaction that releases energy from glucose without using oxygen. It produces lactate in mammals and carbon dioxide and ethanol in yeast.
What is oxygen debt?
The volume of oxygen required to completely oxidise the lactate that builds up in the body during anaerobic respiration is called oxygen debt.
What is metabolism?
The metabolism of an organism is the sum of all the reactions that take place in a cell or in the body.
