Task 1 • Describe the structure of an enzyme as a protein‚ in terms of tertiary/ quaternary structures. 1) Primary Structure This is in reference to the order of way that amino acids are connected to form a protein. These are built up from 20 amino acids‚ and follow these structures o A carbon (the alpha carbon) bonded to the four groups below: o A hydrogen atom (H) o A Carboxyl group (-COOH) o An Amino group (-NH2) o A "variable" group or "R" group 2) Secondary Structure This is in reference

the functions of the main cell components of the body cell. The cell membrane : is something that lets some things in and some things out of the cell. It is an outer cover for the cell. If the cell membrane was non existences the cell would spill all over the place. Its function is to protect the integrity of the interior of the cell by allowing certain substances into the cell‚ while keeping other substances out. It is composed of a thin‚ double-layered sheet of lipids‚ around the Cell and is

Testing Cell Transportation Across a Membrane Introduction Cells have the amazing ability to transport certain molecules in or out of their membrane. Some require no energy to do so (passive transport) while others require energy to be processed through (active transport). There is also the transportation of water across a membrane‚ which has its own term of osmosis. Too much of something can be taken in‚ or too little enters. This especially happens to plants‚ who require water (and sun) to live

revealed a molecular mechanism that directs the chance and role of cells during the process of animal development. The researchers’ discovery shows remarkable findings that are promising in the advancement of cancer and stem-cell research. The hypothesis of this article relates to even though each individual cell contains the complete DNA code‚ only small portions of this DNA code are activated. Therefore‚ the cell has a certain function instead of others. Every single gene in the DNA code is accountable

The Effects of Soccer Headings on Brain Structure and Function Although often overlooked‚ concussions could be one of the biggest injuries a soccer player could front in their career. Many athletes in contact sports focus on showing their skills‚ getting playing time and ignored what the body was telling them to do. Most of the times‚ athletes were brushing off the injuries because they were feeling normal about it‚ particularly in sports like soccer. Soccer was the most popular sport among children
