The enzymes maltases, sucrases, as well as lactases, additionally found in the border of the tiny intestine wall, convert the disaccharides into monosaccharides.

The aforementioned enzymes start breaking down disaccharides after food passes from the stomach and small intestine. This takes place in the small intestine's inner wall's microvillus membrane, also known as the "brush boundary." Disaccharidases were glycoside hydrolases, which are enzymes that convert some kinds of sugars, known as disaccharides, into monosaccharides, which are more basic sugars. Enzymes called glycosidases cleave glycosidic bonds. Lactose, maltose, and sucrose are the three main disaccharides. Sucrose is a compound made up of one glucose molecule and one molecule of fructose joined together by a -,-linkage and is produced by green plants after photosynthesis.

The enzyme-substrate complex is a temporary intermediate formed during an enzyme-catalyzed reaction. It is a combination of the enzyme and its substrate(s) bound together at the enzyme's active site.

The active site is a region on the enzyme's surface that contains specific amino acid residues and other functional groups that can interact with the substrate(s) to facilitate the chemical reaction. When the substrate(s) bind to the active site, the enzyme undergoes a conformational change that forms the enzyme-substrate complex.

The formation of the enzyme-substrate complex is essential for the enzyme to catalyze the reaction and convert the substrate(s) into the product(s). Once the reaction is complete, the enzyme releases the product(s) and returns to its original conformation, ready to bind to another substrate molecule and repeat the process.

So, the enzyme-substrate complex is located at the active site of the enzyme.

Hybrid sterlity. Once the individuals (of two different parent species) have mated and produced a zygote, the postzygotic isolating process is used to isolate the reproduction of those individuals.

A successful initial cross will result in hybrid sterility, but the secondary cross will not work. The fact that the primary cross's offspring have multiple sets of chromosomes may have resulted from the failure of meiotic chromosomal disjunction, which in turn may have caused the condition where multiple sets of chromosomes are present in the primary cross's offspring. As an illustration, a mule, a cross between a female horse and a male donkey, may mature into adulthood yet remain sterile since it is unable to produce functioning gametes.

An outpocketing of the digestive tube gave rise to the swim bladder, which is housed inside the body cavity.

It serves as a hydrostatic organ, or ballast, allowing the fish to maintain its depth without rising or falling, and it carries gas (often oxygen). The fish's buoyancy comes from its swim bladder or air bladder. Only bony fish have it in their bodies. The bony fish uses this organ, which is filled with gas, to manage its buoyancy in the water and prevent sinking. Essentially, it is a tough capillary network covering a sac-like structure. A layer of connective tissue known as the tunica externa lies beneath the capillary system. The tunica interna, which is below this layer and predominantly made up of epithelial gas glands and smooth muscle fibers, is situated. The swim-bladder in fishes can be broadly classified into two groups based on whether or not there is a duct (ductus pneumaticus) between the swim-bladder and the oesophagus.

The correct answer to the question is c. It would likely be targeted to the cytosol because proteins without an ER sequence are translated in the cytosol.

Protein targeting is a process by which proteins are directed to specific cellular compartments or organelles, such as the nucleus, cytosol, ER, Golgi, or extracellular space. The process is regulated by specific targeting signals or sequences within the protein, which direct it to its proper destination.

In the case of glycosyltransferases, these enzymes are normally targeted to the lumen of the Golgi, which is the site of post-translational modification of proteins and lipids. This targeting is mediated by specific ER signal sequences within the protein, which direct it to the ER and then to the Golgi.

If the ER signal sequence of the glycosyltransferase protein is mutated and can no longer function, the protein would likely be targeted to the cytosol during translation, rather than being directed to the ER. This is because proteins without an ER signal sequence are typically translated in the cytosol by default, unless they have other targeting signals that direct them to specific organelles.

Therefore, the correct answer to the question is c. It would likely be targeted to the cytosol because proteins without an ER sequence are translated in the cytosol. It is unlikely that the protein would be targeted to the nucleus or directly to the Golgi, as these destinations require specific targeting signals that are distinct from the ER signal sequence. Similarly, the protein would not be secreted to the extracellular space, as it lacks the necessary signal sequence to be directed to the ER and then to the secretory pathway.

The sequential model for allosteric enzymes was proposed by: Koshland option A

According to this paradigm for allosteric control of enzymes, multimeric protein subunits have two conformational states.  Ligand binding triggers conformational changes in the multimeric protein's other subunits.

Although the subunits undergo conformational changes individually (as contrast to the MWC model), the switch of one subunit increases the likelihood of the other subunits changing by lowering the energy required for following subunits to undertake the identical conformational shift.

The binding of a ligand to one subunit in elaboration modifies the structure of the protein, making it more thermodynamically favorable for the other subunits to flip conformation to the high affinity state.
