1. Anaerobic respiration is fermentation!

Where might you see fermentation in day-to-day life?

a. If you ferment wheats or starches,you get alcohols. If you fermentfruits or honey, you get wine or mead.

a. Fermentation of yeast cells in bakingbread causes it to rise.

a. We use fermentation to make cheesesand yogurts from milk.

a. In things like bread, wine, beer, and otheralcohol, you are using yeast’s anaerobicrespiration to create alcohol and carbondioxide.

a. Some bacteria produce lactic acid, whichhelps make cheese, buttermilk, and yogurt.

a. During long periods of exercise, muscle cells can use oxygen faster than the body can supply it. These cells then switch from aerobic respiration, to anaerobic respiration and produce lactic acid.

b. When lactic acid builds up in the muscle tissue, youget a burning feeling andmuscle fatigue.

c. Once we get enoughoxygen to those cells again,aerobic respiration breaksdown the lactic acid.

1. Anaerobic respiration occurs in the cytoplasm of the cell.

1. You have to start by converting the glucose molecule into two molecules of pyruvic acid.

2. This requires 2 ATP to start the reaction!
