phase and building them into complex molecules such as starch‚ proteins and lipids What is the role of ATP? ATP is the driving force for catabolic and anabolic reactions. ATP stores energy that is produced from the catabolic reactions which is later released to drive the anabolic reaction and other cellular work. ATP is stored energy in cells (phosphate groups held together by high energy reacting bonds) ATP is required for synthesis and some of the energy is given off as heat What are enzymes

Biology Assignment (Haemoglobin) Proteins are large‚ complex molecules that are made up of hundreds or thousands of smaller units called amino acids‚ which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein. The sequence of amino acids determines each proteins unique structure and specific function. They play many critical roles in the cells. They can be grouped as enzymes‚ antibodies‚ messengers‚ structural components or

This information is reviewed in a series of lectures on DNA‚ the genetic code‚ protein synthesis and aspects of molecular biology. The digestion and absorption of biomolecules is reviewed and the consequences of malfunction considered. A number of disease states are used to illustrate selected principles including the relationship between

tissues. A quick summary of thyroid hormone synthesis‚ taken directly from the Kopp article‚ is included at the end of this learning issue. The first step in the action of thyroid hormone is the conversion of T4 to the active T3 by a 5’-iodinase. Once T3 has entered the target cell it enters and binds to a nuclear receptor‚ this complex binds to a specific regulatory element in the DNA where it stimulates DNA transcription and ultimately protein synthesis. Interestingly‚ certain states such as pregnancy

intermediate‚ and reacted with hydrated cobalt to prepare Co(salen). Using Co(salen) the oxygen up-take was tested. The synthesis of SalenH2 produced 0.65 g. The percent yield of salenH2 was 116% on the filter paper and 105% after transferring salenH2 to a vial. The melting point of salenH2‚ was 128 oC. The color of salenH2 was yellow. This was all expected from salenH2. The synthesis of Co(salen) produced 0.232 g. The percent yield of Co(salen) was 88.22% on the filter paper and 86.1 % after transferring

provided to our class for this project‚ I told myself that I wanted a challenge. I wanted to work on a topic that I knew very little about to begin with. Some of the choices off of the ergogenic aid list seemed to easy and broad. Options such as protein and alcohol would seem to be rather easy and bland. To begin with‚ I had heard of amino acids and branched chain amino acids. However‚ I knew next to nothing about them. Instead of covering the broad topic of all the amino acids‚ this topic allowed
