The net gain of atp per molecule of glucose fermented is

net gain is 2 ATP

Explanation:

It is the fermentation that usually happens in yeast. Like fermentation with lactic acid, alcoholic fermentation allows glycolysis to continue by ensuring that NADH returns to its oxidized state (NAD +).

Fermentation produces 4 molecules of ATP per molecule of glucose, compared with 38 by aerobic respiration. Since 2 molecules of ATP are used in glycolysis, the net yield for fermentation is 2 ATP.

since electrons are negative the answer is neagtaive

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
