Anna007 [38]

A baker has created a new strain of yeast which contains no cytochrome c gene and no cytochrome c protein. this will affect what the yeast strain can do to obtain energy. what will this yeast strain do more of compared to a normal strain

Will this new strain of yeast obtain more or less free energy from glucose in its growing medium?

Answer: Less because cytochrome c is key to the electron transport chain.

Explanation:

The Cytochrome c is an essential component of the electron transport chain. Without this there will be no oxidation and reduction of iron atom will take place which could convert the ferrous ions to ferric ions. Thus the entire process of electron transport chain and energy production in the form of ATP will be compromised. So, there will be no production of energy in the anaerobic fermentation by yeast.

What's the difference between nitrification and dentification
Y_Kistochka [10]

Difference between nitrification and dentrification

Explanation:

Nitrification and denitrification are part of the nitrogen cycle

Nitrification is the process of conversion of ammonium to nitrate by nitrifying bacteria like Nitrobacter and Nitrosomonas

Denitrification is the process of reduction of nitrate to nitrogen gas by denitrifying bacteria like Pseudomonos, Lactobacillus etc.

Nitrifying bacteria are autotrophs and grows slowly and need aerobic condition.  Denitrifying bacteria are hetertrophs and grows rapidly and need anaerobic conditions.

Nitrification requires a pH of about 6.5 to 8.0; denitrification takes place at 7.0 to 8.5

Nitrification provides soluble nitrates readily available in the soil to be easily absorbed by the roots.

Denitrification processes are used in wastewater or effluent treatment plants.
