Answer 2

## Step 1The waste gas produced during cellular respiration is Carbon Dioxide.## Step 2ATP Synthase is the molecule that creates ATP whenever H+ ions diffuse through it.## Step 3The final electron acceptor at the end of the mitochondrial ETC is Oxygen.## Step 4Oxygen needed for cellular respiration comes from the air.## Step 5Cells switch to using the process of fermentation when there is a lack of available oxygen. This is also known as anaerobic respiration.## Step 6Cellular respiration is an aerobic process because it requires oxygen.## Step 7Cells prefer cellular respiration because it produces ATP for the cell to use.## Step 8Fermentation cannot make ATP.## Step 9A cell can temporarily switch to fermentation so that glycolysis can continue making ATP.## Step 10Fermentation and cellular respiration are similar in that they both use pyruvates as reactants.## Step 11Yeast cells can perform alcoholic fermentation.## Step 12Lactic acid fermentation in bacteria is used in the production of yogurt and some cheeses.## Step 13Alcoholic fermentation is used in the production of beer, wine, and breads.## Step 14In alcoholic fermentation, pyruvates react to produce alcohol and carbon dioxide.## Step 15Lactic acid fermentation can occur in muscle cells when they are overworked.## Step 16Muscles switch to using lactic acid fermentation when the cell's oxygen demand is lower than the oxygen supply coming from the bloodstream.## Step 17Yeast is a single-celled fungi used in the production of rising breads and alcoholic beverages.
