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.
