Microbes Flashcards
how can we see microbes
by using a microscope
what are the main types of microbes
viruses, bacteria and fungi
what is the most common fungus microbe
yeast
what the biggest microbe
yeast
what is the smallest microbe
viruses
what is the middle size microbe
bacteria
why are viruses not considered a living thing
because they cant carry out any of the seven life processes for themselves
what microbes are useful when making food and drink
bacteria and yeast
what are yeasts used for in cooking
to make bread rise
how does yeast make bread rise
the cells use oxygen, from the air found in pockets in the dough, for aerobic respiration. this process uses carbon dioxide that makes the bread rise
formula for aerobic respiration
glucose + oxygen - carbon dioxide + water
what are yeast used for when making drinks
for making beer and wine
how does yeast make beer and wine
in this case there is no air and so the yeast cells use anaerobic respiration.
what is fermentation
when yeast cells use anaerobic respiration
what is the waste product of anaerobic respiration in yeast
ethanol
