In this document, you can learn about the properties and functions of a water molecule. Furthermore, you can understand the bonding involved in water molecules and how it affects daily cellular activities both in plants and in humans.

In this document, you will be able to learn about the structure of a cell membrane in detail from the types of proteins involved to the function of the proteins to regulate cell activity. You will be able to learn about the model used to describe the cell membrane and the different types of transport of substances through your body like osmosis, diffusion, active transport endocytosis and exocytosis

In this document, we provide a full explanation of the function of a protein, the different types of proteins, the chemical structure, and how different parts of the chemical structure affect its role as a protein molecule. We also explain the 4 main structures and it's different functions as well as the different aspects that help differentiate them. We also provide detailed examples of proteins in a your body, from collagen to fibrous protein to diseases like sickle cell anemia. There is also...

In this document, we touch on what an enzyme is, what is its main function, the structure, active site, different models to show how it works, the activation energy graphs to show the effects of a reaction with and without an enzyme. We also provide a detailed explanation of the different factors affecting enzyme activity and ways to measure enzyme affinity. The document also includes a detailed explanation and procedures for the immobilization of an enzyme, along with the advantages of immobili...
