Fermentation Reactions Quiz - Rayner
Ethyl alcohol & carbon dioxide
What does the use of alcholic fermentation produce?
the process in which glucose is oxidized (reduced) to pyruvate (pyruvic acid)
What is glycolysis?
2 pyruvate + 2NADH → 2 ethyl alcohol + 2CO₂ + 2NAD⁺
What is the chemical equation for alcoholic fermentation?
2 pyruvate + 2NADH → 2 lactic acid + 2NAD⁺
What is the chemical equation for lactic acid fermentation?
To release to the cell energy that was stored in glucose.
What is the purpose of fermentation?
glycolysis
What process begins all reactions?
They both use pyruvic acid and NADH(reactants) to make NAD⁺(product)
What reactants and products do the 2 types of fermentation have in common?
in the cytoplasm
Where does fermentation occur?
Lactic Acid
Which type of fermentation is carried out in the human body?
Glycogen
Body stores energy in the form of the carbohydrate________. (lasts for 15-20 mins of activity)
NAD⁺ is produced in both equations
How are the products of lactic acid fermentation and alcoholic fermentation the same?
In the absence of oxygen, fermentation releases energy from food molecules by producing ATP.
How do organisms generate energy when oxygen is not available?
Lactic Acid fermentation produces lactic acid, and alcoholic fermentation produces alcohol and carbon dioxide.
How do the two types of fermentation differ?
-for short, quick bursts of energy, the body uses ATP already in muscles as well as ATP made by lactic acid fermentation -for longer exercise, cellular respiration is the only process to continually produce ATP
How does the body produce ATP during different stages of exercise?
2 ATP
How many ATP are needed in lactic acid fermentation?
none
How many ATP are produced?
Cellular Respiration ATP
Intense exercise lasting longer than 90 seconds,_____ _____ is required to continue production of ____. (Long-term Energy)
About 90 seconds (extra oxygen is required to get rid of lactic acid produced)
Lactic Acid fermentation can supply enough ATP to last ____. (Quick Energy)
NAD⁺
NADH is oxidized to form______.
Glycolysis
Under anaerobic conditions, fermentation follows______.
alcoholic beverage and yeast rising in bread
What are the most common uses of alcohlic fermentation?
Lactic Acid Fermentation Alcholic Fermentation
What are the two types of fermentation?
cellular respiration
Which process releases energy more slowly?: cellular respiration or fermentation
alcoholic
Yeast is an example of something that carries out _______ fermentation.
oxygen is required for the process to occur
aerobic means______
no oxygen is required for the process to occur
anaerobic means____
fermentation
process by which energy can be released from food molecules in the absence of oxygen
lactic acid fermentation
type of fermentation using a chemical reaction that converts pyruvic acid to lactic acid
