How does streptococci tolerate 02?
Streptococci are facultative anaerobes, meaning they can grow in both the presence and absence of oxygen. They tolerate oxygen by using fermentation pathways to generate energy, producing lactic acid as a byproduct. Additionally, some species possess enzymes like superoxide dismutase and catalase, which help mitigate oxidative stress by neutralizing harmful reactive oxygen species. This allows them to survive and thrive in environments with fluctuating oxygen levels.
What is Lance Armstrong's resting pulse rate?
His heart is stronger as well as being significantly larger. Per pump (stroke, beat), his trained heart can output a greater volume of blood than an untrained person (let's called the untrained person Joe Normal). So at rest, both Armstrong and Joe need to move the same volume of blood around per minute to keep everything oxygenated. Each beat of Armstrong's heart is going to move twice as much blood as a beat from Joe's. As a result, Armstrong's heart only needs to beat half as often to keep things oxygenated. How did this happen? Lots and lots of cardiovascular training. As the heart gets trained, it gets stronger and larger - it is a muscle, just like your biceps grow after multiple bicep curls in the gym. When Lance is sprinting as fast as he can, his heart is not pumping much more often than when a non-athlete is sprinting - but it's pumping out more blood per beat so he can go further and faster since his muscles can remain better oxygenation, produce less lactic acid and take longer to fatigue.
What is different between the two types of fermentation?
There are two types of fermentation: Alcoholic Fermentation and Lactic Acid Fermentation. Both types have the same reactants: Pyruvic acid and NADH, both of which are products of glycolysis. In alcoholic fermentation, the major products are alcohol and carbon dioxide. In lactic acid fermentation, the major product is lactic acid. For both types of fermentation, there is a side product: NAD+ which is recycled back to glycolysis so that small amounts of ATP can continue to be produced in the absence of oxygen.
What are the 2 types of fermentation and what do each produce?
The two types of fermentation are alcoholic fermentation and lactic acid fermentation. Alcoholic fermentation is also referred to as ethanol fermentation.
What do both lactic fermentation and alcoholic fermentation produce?
Both lactic fermentation and alcoholic fermentation produce energy in the form of ATP for cells. Lactic fermentation results in the production of lactic acid, while alcoholic fermentation produces ethanol and carbon dioxide as byproducts.
What are the two of fermentations?
alcoholic fermentation and lactic acid fermentation
Alchoholic fermentation and Lactic Acid fermentation?
Yes? lactic acid fermentation produces only lactic acid alcoholic fermentation produces ethanol and co2
Both lactic acid fermentation and alcoholic fermentation produce?
Both lactic acid fermentation and alcoholic fermentation produce ATP as a form of energy for the cells. Additionally, both processes also produce waste products, such as lactic acid in lactic acid fermentation and ethanol in alcoholic fermentation.
What types of fermentation are there?
Alchoholic fermentation and Lactic Acid fermentation
What is the difference between the two fermentation?

For both types of fermentation, there is a side product: NAD+ which is recycled back to glycolysis so that small amounts of ATP can continue to be produced in the absence of oxygen.
What are the two kinds of fermentation?
The two main kinds of fermentation are alcoholic fermentation, which produces ethanol and carbon dioxide, and lactic acid fermentation, which produces lactic acid. Alcoholic fermentation is commonly used in brewing and winemaking, while lactic acid fermentation is used in the production of foods like yogurt and sauerkraut.
How are lactic acid fermentation and alcoholic fermentation different?
alcohol is stronger
What do both lactic-acid fermentation and alcoholic fermentaion produce?
Both lactic acid fermentation and alcoholic fermentation produce energy (in the form of ATP) and end products that help regenerate NAD+ so that glycolysis can continue. Lactic acid fermentation produces lactic acid, while alcoholic fermentation produces ethanol and carbon dioxide.
How the lactic acid fermentation and alcoholic fermentation?
Lactic fermentation transform sugars having six carbons in lactic acid.Alcoholic fermentation transform sugars in ethanol and carbon dioxide.
