Biology- Breathing and respiration Flashcards
what life processes is energy needed for?
> growth and repair
movement
control of body temperature in mammals
what is respiration?
respiration is a chemical reaction, when energy is released from glucose so that other chemical processes can happen.
what is the word equation for fermentation?
glucose=ethanol+carbon dioxide.
what is the formula for how lactic acid breaks down?
lactic acid + oxygen=carbon dioxide + water
___________ carries blood to the heart
vein
__________ carries blood from the heart
arteries
true or false?
the right side of the heart is oxygenated.
FALSE! the right side is deoxygenated the left side is the side that is oxygenated
what are capillaries?
Capillaries are small blood vessels which allow nutrients to pass across the membrane into nearby cells
why does your heat rate increase during exercise?
This is because your muscles cells need more glucose and more oxygen to allow for respiration
what does ventilation mean?
getting air into and out of the lungs.
mechanism of moving air into and out of your lungs
word equation for breathing?
breathing=ventilation+gas exchange
what is aerobic respiration?
the release of energy using oxygen
what is anaerobic respiration?
the release of energy without oxygen.
what is the word equation for aerobic respiration?
glucose+oxygen=carbon dioxide +water (some energy)
what is the word equation for anaerobic respiration?
glucose=lactic acid+some energy
what is the anaerobic respiration formula for plants and yeast?
glucose= alcohol +carbon dioxide +(some energy)
