Absence of oxygen means anaerobic respiration ; which has 2 different pathways.
First Pathway ; Alcoholic fermentation which takes place in yeast.
Pyruvate is decarboxylated into ethanal releasing co2 as waste product.
Ethanal is toxic , so its reduced by help of NADH to ethanol in presence of alcohol dehydrogenase enzyme , and Free NAD is released to continue glycolysis.
2) The second pathway is Lactic fermentation which takes place in mammalian muscles.
Pyruvate accepts hydrogen and is converted to lactate by the help of enzyme lactate dehydrogenase , again free NAD is released to continue glycolysis.
Hope I made it clear enough :)
<h3><u>Answer;</u></h3>
peptidoglycan
The molecular basis of the Gram stain is the amount of<u> peptidoglycan</u> in the bacterial cell wall.
<h3><u>Explanation</u>;</h3>
- Gram stain is differential stain that is very useful for identifying and classifying bacteria as either gram negative or gram positive.
- Gram negative are those that decolorize easily, such as E. coli, while Gram positive are those that retain the primary stain and do not decolorize easily.
- The result depends on the bacteria cell wall structure, the cell wall of a Gram-negative bacterium is composed of 20 percent or less of peptidoglycan.
Answer:
could be either or, but the name of the shape is a double helix.
Explanation:
Answer:
In the lab, I discovered the air pressure, air temperature, and relative humidity conditions that create snow, rain, thunderstorms, fog, and clear skies. I learned that low-pressure areas usually experience snowy, rainy, and stormy weather, and that high-pressure areas usually experience either foggy or sunny weather. Knowing how these atmospheric conditions influence weather help weather forecasters predict weather patterns through maps and other information.
