A new protein namely protein X has been isolated by molecular biologists. The protein is shown to have a spherical shape and a radius of 12 nm. Before they could measure its diffusion coefficient at 25°C, their device breaks. However, they have data from a previous measurement taken using the same device, at 25°C which showed diffusion coefficient of albumin (spherical with R=3 nm, M= 68,000 g/mol) to be 6.8x10-7 cm2/s. Determine the diffusion coefficient of protein X
Enzyme kinetics
In biochemistry, enzymes are proteins that act as biological catalysts. Catalysis is the addition of a catalyst to a chemical reaction to speed up the pace of the reaction. Catalysis can be categorized as either homogeneous or heterogeneous, depending on whether the catalysts are distributed in the same phase as that of the reactants. Enzymes are an essential part of the cell because, without them, many organic processes would slow down and thus will affect the processes that are important for cell survival and sustenance.
Regulation of Enzymes
A substance that acts as a catalyst to regulate the reaction rate in the living organism's metabolic pathways without itself getting altered is an enzyme. Most of the biological reactions and metabolic pathways in the living systems are carried out by enzymes. They are specific for their works and work in particular conditions. It maintains the best possible rate of reaction in the most stable state. The enzymes have distinct properties as they can proceed with the reaction in any direction, their particular binding sites, pH specificity, temperature specificity required in very few amounts.

Protein:
Proteins are necessary nutrients for human health. They are a component of body tissue and can also be used as a fuel source. Proteins have the same energy density as carbohydrates: 4 kcal (17 kJ) per gramme; lipids, on the other hand, have 9 kcal (37 kJ) per gramme. From a nutritional standpoint, the amino acid content of protein is the most significant element and distinguishing property.
Proteins are polymer chains that are made up of amino acids that are linked by peptide bonds. Proteins are broken down into smaller polypeptide chains in the stomach during human digestion by hydrochloric acid and protease enzymes. This is necessary for the absorption of vital amino acids that the body cannot produce.
