In downstream processing of gluconic acid, concentrated fermentation broth containing 20% (w/w) gluconic acid is cooled in a heat exchanger prior to crystallisation. 2000 kg h^-1 liquid leaving an evaporator at 90°C must be cooled to 6°C. Cooling is achieved by heat exchange with 2700 kg h^-1 water initially at 2°C. The final temperature of the cooling water is 50°C. 

Assume (heat capacity of gluconic acid is 0.35 cal g^-1 °C^-1).

h (liquid water at 90°C = 376.9 kJ kg^-1)

h (liquid water at 6°C = 25.2 kJ kg^-1)

h (liquid water at 2°C = 8.4 kJ kg^-1 )

h (liquid water at 50°C = 209.3 kJ kg^-1)

h (gluconic acid at 90°C=0)

How much heat is removed to the cooling water?

A very important function of the Golgi apparatus and endoplasmic reticulum is the synthesis of another organelle, the lysosome. This organelle is found in a variety of organisms such as—

1.Protozoa 

2. Some algae

3. Fungi

4. Plants 

5. Animals

In which of the above organisms lysosome is not found.
