In situations where there are elevated levels of sulfanilamide alongside an enzyme with paba as its substrate, the enzyme's activity will be inhibited by the sulfanilamide, leading to a cessation of its function. Hope this clarifies your question. Have a great day.
Every cell is encased in a protective layer referred to as the cell membrane. In plants, an additional barrier known as the cell wall offers further protection. All organelles found within cells are enclosed structures.
Cell membranes consist of a phospholipid bilayer featuring both extrinsic and intrinsic proteins. Studies of the plasma membrane structure revealed that the protein patterns of MITOCHONDRIA and CHLOROPLAST are most akin to that of the cell membrane.
The active site of the enzyme accommodates a substrate. This leads to the formation of an enzyme-substrate complex as the enzyme binds with the substrate. Subsequently, a chemical reaction takes place where new substances, referred to as products, are generated.
