What is mixed-acid fermentation? how is methyl red used to determine if a microbe has undergone mixed-acid fermentation?

Biology

Mixed Acid Fermentation is a biological process by which a six carbon sugar is converted into complex mixture of acids. It is an example of anaerobic fermentation reaction which is commonly seen in bacteria.

The fermentation produces lactate, acetate, succinate, formate, ethanol, H_{2} and CO_{2} and their formation depends upon the presence of certain key enzymes in the bacterium.

The Methyl Red test is used in detecting occurring of mixed acid fermentation pathway when glucose is provided to microbes by using ph indicator. If the fermentation pathway has taken place, the mixture of acids will make the solution very acidic and causes red color change. The Methyl Red test belongs to the group called as IMViC tests.

Why do plant cells have chloroplasts, but animal cells do not
ad-work [718]
<h2>Mark me brianliest plz I really need it</h2>

Explanation:

<h2>In order to do photosynthesis, a plant needs sunlight, carbon dioxide (CO2) and water. Once the sugar is made through photosynthesis, it is then broken down by the mitochondria to make Page 2 energy for the cell. Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.</h2>

4 The graph below shows how the activity of an enzyme changes
choli [55]

Answer:

A

Explanation:

A. The optimum pH of the enzyme is 6.6.  - this is true. The optimum pH of the enzyme is where its activity is the highest. On the graph, this is pH 6.6 (activity at 100)

B. The optimum pH of the enzyme is 5.8.  - this is false, the activity of the enzyme peaks at 6.6 (100), at 5.8 the activity is 80

C. The enzyme's activity is greater around pH 8.0 than around  pH 5.0  - This is false, the activity at pH 5 is 50, whereas at around 8 it is 20.

D . The enzyme's activity continually increases as pH increases  from 5.0 to 9.0 - this is false. The activity drops between pH 6.6 and pH 9.

A Tropical Rain Forest biome is normally limited to low altitudes near the equator.
Kay [80]

Answer:

True

Explanation:

Tropical rain forest are one of the important biomes of the world that is characterized by a short or no dry season and a precipitation of overall 60 mm each month. They are also known as lowland equatorial evergreen rainforest. If we talk about location, they mostly are found between  fall between the Tropic of Cancer and the Capricorn since they lie near to equator and they receive sufficient amount of sunshine and rain.

Due to their location near the equators, they receive greater amount of sunshine than other biomes and when sunshine is greater the rate of water evaporation is also greater that results in more rainfall.


Hope it help!
