1.	Which of the following examples are not related with the class of metabolite, that is “Products indirectly associated with energy generation”?(a) Lactic acid(b) Amino acid(c) Nucleotides(d) Citric acidThis question was addressed to me in unit test.My question comes from Production Kinetics in Cell Culture in portion Homogenous Reactions of Bioprocess Engineering
Answer» Correct answer is (a) Lactic acid Explanation: Lactic acid comes under the first category of the class of metabolite that represents PRODUCTS directly associated with GENERATION of energy in the cell. Compounds in the first category are formed directly as end- or by-products of energy METABOLISM; these materials are synthesised in PATHWAYS which produce ATP. Examples include: Ethanol, acetic acid, gluconic acid, acetone, BUTANOL, lactic acid, other products of anaerobic fermentation.

Consider the growth of a microorganism in batch culture. When the substrate concentration is high, the cell density doubles every 0.75 h, the observed substrate yield coefficient is 0.3 g DCW/g, and substrate consumption is allocated towards biosynthesis (60%), maintenance (10%), as well as product formation (30%).
