Their antibody is composed by subunits that have molecular weights of 50 kD and 25 kD, and each of these subunits has one Cys residue at least.
<u>Their antibody is composed by subunits that are conected by an S-S bond that takes place in their Cys residue.</u> When the antibody is treated with a reducing agent, these S-S bond are reduced to S-H, thus the subunits are no longer connected to each other.
The original antibody weights 150 kD, as seen in Lane 1. And the combination of these subunits are seen in Lane 2: this means there is not only one subunit of 50 kD and one of 25 kD. Rather, these subunits are repeated in the antibody, in a way such that their combined weight add ups to 150 kD (for instance 2 subunits of 50 kD and 2 subunits of 25 kD).
At a constant pressure the production of heat will be 25.9 KJ.
The heat produces at constant pressure will be more as compared to the heat produced at constant volume because,
At a constant pressure there is some work done and heat is used in this process. All the heat is not going to change the temperature. while,
At constant volume there is no work done and all the heat is going to change the temperature. In other words we can say that it take less heat to produce the temperature change at a constant volume as compared to at constant pressure.

So, when 1.5 g of fuel is burn at constant pressure it will produce 25.9 KJ. while at constant volume it will produce 23.3 KJ.
