need to know Flashcards
how is glucose moved from the small intestine to the muscle cells
glucose is absorbed by diffusion into the blood stream which is delivered to muscles in capillaries
what is the use of liquid paragon in an anaerobic respiration experiment
to stop air getting in
how could an experiment be adapted to collect gas
use a measuring cycle we or gas syringe
compare anaerobic respiration in a yeast cell with anaerobic respiration in a muscle cell
yeast produces ethanol but muscles produce lactic acid
yeast produces co2 and muscles don’t
both release small amounts of energy
how is the strucure of an artery different to a vein
arteries have smaller lumen and thicker walls arteries don’t have valves
what type of blood do arteries and veins carry
arteries carry oxygenated veins carry deoxygenated
arteries have more glucose
arteries have less CO2 and less lactic acud
why might someone run faster than someone else
they send more blood to muscles body heart which supplies more oxygen which supplies more glucose therefore faster rate of respiration which removes lactic acud
which blood vessel transports blood from body to right atrium
vena cava
