Summarize the process of alcoholic fermentation in yeast

Chemistry
1 answer:
AysviL [449]4 years ago
6 0

Alcoholic fermentation is mainly used by various yeast species to make energy.

If there is no oxygen available, the yeasts have in the alcoholic fermentation another possibility of energy supply. But they can - as compared with cellular respiration - recover substantially less energy from glucose, in the form of adenosine triphosphate (ATP): by complete oxidation, a molecule of glucose provides 36 molecules of ATP, but by alcoholic fermentation only 2 molecules of ATP. These two molecules are obtained in glycolysis, the first step in the chain of reactions for both cellular respiration and fermentation.

The two additional steps of the fermentation, and thus the production of ethanol serve not to make energy, but the regeneration of the NAD + cofactor used by the enzymes of glycolysis. As NAD + is available in limited quantities, it is converted by the NADH reduced state fermentation enzymes to the NAD + oxidized state by reduction of acetaldehyde to ethanol.

Compare and contrast alpha beta and gamma radiation
Evgen [1.6K]
There are usually 3 topics used to compare types of radiation: 

Ionising ability
Penetrative power 
Range in air

Ionising ability
Alpha radiation has strong ionising ability, while beta only has moderate ionisation and gamma is very weakly ionising.

Penetrative power 
Alpha particles are weakly penetrating, stopped by paper, while beta particles have stronger penetrating ability, stopped by skin and gamma radiation is very strongly penetrating, stopped only by thick layers of lead.

Range in air
Alpha particles- range of only a few centimetres
Beta - range of up to one meter 
Gamma- infinite range in air.

Hope this helps:)

We expect the enthalpy of cumbustion of two isomers to be _________. The molecular formulas of two molecules are _____, so the b
Alex777 [14]

Answer:

We expect the enthalpies of combustion of two isomers to be different.

The molecular formular of the two molecules are very similar.

So the balanced chemical equation for the two combustion reactions are the same.

Explanation:

In calculation of the combustion enthalpiesfrom the isomers of the products and reactant.

The difference will be in the standard enthalpies of formation of the two combustion products.

The rod-shaped n- octane has vibrational and rotational motion possible more than the almost spherical neoprene.
