The oxygen released during photosynthesis process comes from

The oxygen released during photosynthesis process comes from Correct Answer H<sub>2</sub>O

During the process of photosynthesis, green plants and some other organisms use sunlight to convert carbon dioxide (CO2) and water (H2O) into glucose (a type of sugar) and oxygen (O2). This process takes place in the chloroplasts of plant cells and is represented by the following chemical equation:

6 CO2 + 6 H2O + light energy → C6H12O6 + 6 O2

As you can see, the oxygen released during photosynthesis comes from the water molecule (H2O). Carbon dioxide (CO2) is used to produce glucose (C6H12O6), which serves as an energy source for the plant. So, the correct answer is Option A: H2O.

In a well aerated and agitated microbial culture, the 'supply' of oxygen is equal to 'demand' (uptake) of the growing culture. The KLa for such a system will be (KLa = volumetric mass transfer coefficient, C* = dissolved oxygen concentration in liquid in equilibrium with gaseous oxygen, C = instantaneous value of dissolved oxygen concentration, 'r' = specific oxygen uptake rate per unit weight of cells, X = dry weight of the cells per unit volume)
A bacterial culture having a specific oxygen uptake rate of 5 mmol O2 (g DCW)-1 hr-1 is being grown aerobically in a fed-batch bioreactor. The maximum value of the volumetric oxygen transfer coefficient is 0.18 s-1 for the stirred tank bioreactor and the critical dissolved oxygen concentration is 20% of the saturation concentration (8 mg mL-1). The maximum density to which the cells can be grown in the fed-batch process without the growth being limited by oxygen transfer, is approximately
