Alcohol Fermentation In Yeast Flashcards
Two ways to extract energy from food
Aerobic respiration
Anaerobic respiration
What can the energy from good be used for
To power growth, reproduction, and other metabolic processes
Most organisms use what type of respiration?
Aerobic
What is aerobic cellular respiration?
Uses oxygen to release energy from carbohydrates
Equation for aerobic respiration?
Carbohydrates + Oxygen = Carbon Dioxide + Water + Energy
One glucose molecule can produce enough energy to produce what during aerobic?
38 ATP molecules
What is anaerobic respiration?
When cells release energy from food when there is no oxygen
One glucose molecule can produce enough energy to fill what through anaerobic respiration?
2 ATP molecules
When you are exercising really hard what happens?
Your breathing rate increases to provide more oxygen to the cells
If oxygen isn’t delivered fast enough to muscle cells what happens?
They carry out lactic acid fermentation a type of anaerobic respiration
What are we studying?
Alcoholic fermentation in yeast cells, which carry it out when they are deprived of oxygen
Equation for anaerobic respiration
Carbohydrates = Carbon Dioxide + Ethanol + Energy
What uses alcoholic fermentation?
Bread
Cheese
Fuel
What is the task?
To create ethanol for cars efficiently and at a low cost
