what is the word equation for Aerobic respiration in humans
Glucose + oxygen —> Carbon dioxide + water
what is the balanced symbol equation for Aerobic respiration in humans
C6H12O6 + 6O2 —-> 6CO2 + 6H2O
what is the word equation for anaerobic respiration in human
Glucose —> carbon dioxide + lactic acid
what is the word equation for anaerobic respiration in YEAST
Glucose —> ethanol + carbon dioxide
why does bread rise?
yeast produces co2, gas bubbles cause bread to rise
What is oxygen debt process
-take in extra oxygen
-replenish oxygen levels
-oxygen enables body to break down lactic acid into glucose to remove co2
what does diaphragm do
thick muscular band that separates the thorax from the abdomen. contracts and relaxes
what do alveoli do
site of gas exchange in lungs
what does mucus do
sticky substance that traps foreign substances , dirt and pathogens
what do intercostal muscles do
connect to ribs to allow movement
what does trachea do
tube containing CARTILAGINOUS RINGS to allow air to move through
what happens in inhalation
Diaphragm muscles contract / flattens
external intercostal muscles contract (pulls ribs up and out)
what happens in exhalation
diaphragm muscles relax (dome shaped)
internal intercostal muscles contract (pulls ribs down and in
adaptation of alveoli
One cell thick (short diffusion distance)
