bioenergetics - Biology Flashcards
what type of exercise uses aerobic respiration?
long. low-intensity exercise
give a couple of examples of exercise that would use aerobic respiration
cycling, jogging
is aerobic respiration exothermic or endothermic?
exothermic - the breaking down of glucose releases energy
what is the symbol equation for aerobic respiration?
C₆H₁₂O₆+ 6O₂ → 6CO₂ + 6H₂O
what is the word equation for anaerobic respiration?
glucose → energy + lactic acid
what type of exercise uses anaerobic respiration?
short, high-intensity exercise
give a couple of examples of exercise that would use anaerobic respiration
sprinting, long jump
why do athletes get fatigue?
due to the accumulation of lactic acid in the muscles
what is the equation for oxidising lactic acid?
lactic acid + oxygen → carbon dioxide + water
what are some effects a person might experience after anaerobic exercise?
increase in breathing volume
what is oxygen debt?
the amount of oxygen the body needs to remove lactic acid after anaerobic exercise
label some effects that your heart does after exercise
increases heart rate, dilates the arteries to your muscles
why does temperature raise when doing exercise?
exercise (both aerobic and anaerobic), are exothermic, so energy is lost as heat
what happens to your glycogen when doing exercise?
it is converted back into glucose for respiration
what is the definition of metabolism?
the sum of all the chemical reactions in a cell or body
