Bioenergetics Flashcards
What is the word equation for photosynthesis?
Carbon dioxide + water > glucose + oxygen
How is glucose used?
Respiration, converted into insoluble starch, production of cellulose, to produce amino acids
Is respiration endothermic or exothermic?
Exothermic
How is anaerobic respiration different from aerobic respiration?
Aerobic respirationtakes place using oxygen, whilst anaerobic respiration takes place without oxygen
What is the word equation for aerobic respiration?
Glucose + oxygen > carbon dioxide + water
What is the word equation for anaerobic respiration in muscles?
Glucose > lactic acid
What is the word equation for anaerobic respiration in plants and yeast cells?
Glucose > ethanol + carbon dioxide
What is anaerobic respiraion in yeast cells called?
Fermentation
How does the body respond to exercise?
Heart rate, breathing rate and breath volume increase to provide the muscles with more oxygenated blood
How does lactic acid build up affect exercise?
An oxygen debt is created
What is oxygen debt?
The amount of extra oxgen needed to react with the lactic acid and remove it from cells
What is the metabolism?
The sum of all the reactions in a cell or the body
