These enzymes are often especially sensitive towards biochemical purification protocols and need strictly optimised solubilisation conditions to retain activity. For some of these enzymes purification in active form has never been achieved. This explains the difficulty in assigning a sequence to some of ...
Identify if the following statement generally applies to prokaryotes, eukaryotes, bacteria, and/or archaea: Smart, circular pieces of DNA called plasmids, which are easily transferred, can often be found in cells. What do all eukaryot...
This is due to the molecules moving faster and colliding more often together. However at a certain point the temperature gets to high and the enzymes denature and stop functioning. This is due to the heat causing vibrations within the enzyme destroying its structure by breaking the bonds in ...
Why aren't enzymes used more often for drug synthesis?Why do enzymes often require cofactors to facilitate activity?Why are all enzymes hormones, but all hormones are not enzymes?Why enzyme action is considered highly specific?What is the role of enzymes as a catalyst?
Often name of enzyme ends in ase (e.g. ATPase or protease).;4. Explain why enzymes are so specific in the reactions that they catalyse. 5. Suggest why all enzymes are protein molecules. 6. The name given to enzymes that catalyse the breakage of peptide bonds is proteases. What name ...
These often include higher product quality, lower manufacturing cost, less wastage, and reduced energy consumption. Traditional synthetic chemical treatments are generally non-specific, hard to control, and may create uneven conditions. Food processors are choosing enzymes as a cost-effective and safe ...
For our model, these constraints are that (i) the total amount of enzymes must equal ET, (ii) ρ(r) and e(r) must jointly satisfy the reaction-diffusion-advection equation, Eq. (1), at each point r, and (iii) ρ(s) and eS(s) must jointly satisfy the boundary condition, Eq. ...
If the urge is not acted upon, the material in the rectum is often returned to the colon where more water is absorbed. If defecation is delayed for a prolonged period, constipation and hardened feces results. Anal Canal – the feces are passed along from the rectum into the anal canal ...
The reason for this is that these enzymes are often secreted in low quantities. Molecular cloning and overproduction in a suitable host of these enzymes, although not easy, its a way to obtain sufficient quantities of pure enzymes, which in turn allows to assess their significance in various ...
