You inoculated two test tubes with the same amount of identical growth medium and withthe presence or absence of oxygen. After 12 hours, all of the glucose in each culture has beenconsumed. You determined the number of total cells found in each culture and find that oneculture has more cells than the other.(i)Which culture would have the greater cell density, the one grown aerobically or theone grown anaerobically?(ii)Explain why the culture you chose above can make more cells with the same amountof glucose than the other culture.(iii)The cells of both cultures convert glucose to pyruvate via glycolysis, and then furthermetabolize pyruvate. Are the cells of both cultures able to obtain the same amount ofATP from glycolysis? Explain.

Hello, PLease answer. A new chemotherapeutic drug kills bacteria but not humans. Discuss the possible ways the drug may selectively act on bacterial cells.
2C. A “pulse-chase" experiment using "C-labeled glucose can be carried out on a yeast extract that is maintained under strictly anaerobic conditions. The experiment consists of incubating a small amount of "C-labeled substrate (the pulse) with the yeast extract just long enough for each intermediate in the fermentation pathway to become labeled. The label is then “chased" through the pathway by the addition of excess unlabeled glucose. The chase effectively prevents any further entry of labeled glucose into the pathway. 2 ADP 2 ATP Glucose ---> CH3 2 NAD* 2 NADH 2 Pyruvate H H H-C-OH C=0 CH3 CH3 2 co, 2 Ethanol 2 Acetylaldehyde (1) If [1-"C]glucose (glucose labeled at C-1 with "C) is used as a substrate, will there be any "C in the product (ii) Lactic acid is the final fermentation product in vertebrates, while ethanol is the final fermentation product in yeast. Lactic acid can be converted back into glucose while ethanol can not be. In the space below, use a thermodynamic rationale to…

QI. Drag and drop into the biological passage the correct concepts. Living organisms grow because All life forms duplicate themselves using the materials in the body in the process called internal. Animals have the ability to move from one place to another hence animals are locomotion or mobility. Food taken into the body by the animals or absorb by the roots of the plants are processed chemically which involves the breakdown and synthesis known as multiply which is mostly while plants are fixed in a place therefore sessile. This characteristic is called The food that is eaten is a bundle of biological for the total functioning of the body. The biological systems need large molecules in the form of starches and sugar as , glycerol and as lipids, amino acids in DNA and RNA in These large biological molecules are made of complex subunits of polymers which are composed of smaller molecules called and hydrogen.

L-lysine is being produced by Corynebacterium glutamicumin a bioreactorusing glucose as the carbon source, ammonia as the nitrogen source. The bacteria grow aerobicallyin a continuous process at steady-state.All streams of this process are aqueous. In the inlet stream, 8 grams of glucose is included per 100 grams of stream liquid, which flows at a rate of 500 kg/h. The flow rate of glucose in the outlet steam is 1 kg/h.The reaction occurs at 25 °C. According this does the growth of Corynebacterium glutamicum cells inside this bioreactor release or absorb heat? Should heat be supplied to the bioreactor, or removed from, to maintain the operation temperature?
