what is respiration?
a type of chemical reaction that breaks down glucose
what is aerobic respiration?
breakdown of glucose and releasing energy
what does aerobic mean?
with oxygen
what is breathing?
a gas exchange in alveoli of the lungs
what is glucose in animal cells and what does it cause?
lactic acid - stitch/cramp
what does anaerobic mean?
without oxygen
when does anaerobic occur?
when the body’s cells cannot get enough oxygen
what is anaerobic respiration?
the incomplete breakdown of glucose in the absence of oxygen
what is anaerobic respiration in yeast?
fermentation
what are yeast cells?
single celled eukaryotic organism
what are reactants in aerobic respiration?
glucose and oxygen

what are products in animals in anaerobic respiration?
lactic acid
what are products in yeast cells in aerobic respiration?
carbon dioxide and water
what are products in yeast cells in anaerobic respiration?
ethanol and carbon dioxide
how much energy is released in aerobic respiration?
more energy than anaerobic
how much energy is released in anaerobic respiration?
no energy
how does glucose move in the body?
by diffusion
what happens to our muscles when we exercise?
they contract more often
what is the recovery period of heart and breathing rates?
when there is oxygen debt
what is oxygen debt?
when there is an extra amount of nitrogen dioxide your body needs after exercise
what happens when lactic acid enters the blood?
it is transported to the liver where it is converted back into glucose
where in the cell does aerobic respiration take place?
mitochondria
