The 2 types of fermentation are called

Hi

There are two types of fermentation:

Both of them are basically methods of anaerobic respiration in

Lactic acid fermentation occurs in some bacteria and in some tissues of animals( like skeletal muscles and Red blood cells). In this process glucose is converted into energy and a by product called Lactate is formed. This type of fermentation is also used in food and brewing industry where lactic acid bacteria are used for the synthesis of different products.

Alcohol fermentation on the other hand is used by some microorganisms like yeast for the production of energy.  The byproduct that is formed along with ethanol.  

Hope it helps!

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
