alcoholic fermentation

pyruvic acid changes to alcohol and carbon dioxide

lactic acid fermentation

pyruvic acid from glycolysis changes to lactic acid

What is the main advantage of aerobic respiration? Of anaerobic respiration?

Aerobic respiration creates more ATP. Some bacteria only live in anaerobic respiration

Explain why bread dough rises when it is set aside in a warm place.

Alcholic because i uses the carbon dioxide

fermentation

An important way of making ATP without oxygen is called fermentation. It involves glycolysis but not the other two stages of aerobic respiration. Many bacteria and yeasts carry out fermentation. People use these organisms to make yogurt, bread, wine, and biofuels. Human muscle cells also use fermentation. This occurs when muscle cells cannot get oxygen fast enough to meet their energy needs through aerobic respiration

What is fermentation?

It is when cells do not have oxygen and they need ATP. They turn the pyruvic acid into either alcholol or lactic acid

Tanya is on the high school track team and runs the 100-meter sprint. Marissa is on the cross-country team and runs 5-kilometer races. Explain which type of respiration the muscle cells in each runner's legs use.

Marissa uses aerobic, while Tanya uses anaerobic

What process produces fuel for motor vehicles from living plant products? What is the waste product of this process?

alcoholic - Waste is carbon Dioxide

Compare and contrast lactic acid fermentation and alcoholic fermentation. Include examples of organisms that use each type of fermentation.

alcoholic - yeast lactic - Humans

Name two types of fermentation.

lactic acid fermentation and alcoholic fermentation
