Batch fermentation of glucose to ethanol yields a productivity of 4.5 g-1L h-1. If the yeast cell concentration in the fermentation broth is 5% (v/v) and the intracellular NAD+/NADH concentration in the yeast cells is 10 μM, the cycling rate of NAD+ ⇌ NADH will be
A bacterial culture with an appropriate biomass composition of CH1.8O0.5N0.2 is grown aerobically on a defined medium containing glucose as the sole carbon source and ammonia being the nitrogen source. In this fermentation, biomass is formed with a yield coefficient of 0.35 gram dry cell weight per gram of glucose and acetate is produced with a yield coefficient of 0.1 gram acetate per gram of glucose. The respiratory coefficient for the above culture will be
During digestion, carbohydrates are broken down to form glucose. This glucose combines with oxygen in the cells of our body and results in product (A), Product (B) and provides energy. Identify the product A and B.
Two stores A and B bought the same product from the company at the same price. Store A marked the price of the product 50% above its cost price and offered two successive discounts of 15% and 10% on the marked price of the product, while store B marked the price of the product 60% above its cost price and offered two successive discounts of 15% and 12% on the marked price of the product. If a customer buys the product from store B, he has to pay Rs. 986 more than that at store A. At what price the two stores bought the product from the company?

Determine the correctness or otherwise of the following Assertion (A) and Reason (R).
Assertion: Cell mass yield of a methylotrophic yeast is more on methanol compared to glucose.
Reason: Methanol has a greater degree of reductance compared to glucose.
Mention if the following statement is true or false about the difference between fermentation and aerobic respiration? Statement: Fermentation accounts for only a partial breakdown of glucose whereas in aerobic respiration it is completely degraded to CO2 and H2O. 
"Substances added prior to or simultaneously with the fermentation which are incorporated without any major change into the molecule of the fermentation product and which generally cause increases in the yield or improves the quality of the product" can be referred to as
