All living things require the input of energy to exist – this energy is used to drive the thousands of biochemical reactions that occur to allow the organism to grow‚ reproduce and sustain life. This energy comes almost always from the Sun‚ in the rst instance – energy from sunlight is captured by photosynthetic organisms (e.g. plants‚ algae‚ certain bacteria) and converted into carbohydrates. These are then broken down by a process called cellular respiration‚ to produce energy-rich molecules (e

The biochemical importance of water Sam Ellick 13/11/2010 Water otherwise known as H2O is a necessity for life to exist. It has many unique features compared to other molecules of its size. For example solid ice is less dense than liquid ice‚ which ponds and lakes freeze from the top down. This is important in insulating the aquatic life in the winter. This essay however will be looking at why water is so important in biochemical terms. Its shape Water‚ as its formula H2O suggests‚ consists

environmental nutrient levels is critical for life. Yeast cells‚ such as Saccharomyces cerevisiae‚ have the ability to sense and adapt to nutrient levels in their external and internal environment. This ability to sense and adapt to nutrient levels play an essential role in their survival‚ such as to regulate many physiological processes like‚ metabolism‚ cell development‚ cell proliferation‚ protein synthesis‚ translation‚ and cell death; autophagy. One main sensor for nutrient sensing in Saccharomyces cerevisiae

Biol 130 Tuesday October 23‚ 2012 In an organism‚ almost every dynamic function relies on proteins. A protein ’s function is a direct result of their intricate folding‚ the simplest level of which is the sequence of amino acids. (Fitzpatrick et al‚ 2011). Each amino acid has a unique characteristic because of the physical and chemical properties in their side chains‚ which affects the function of a protein. (Alberts et al‚ 2010). After a cell synthesizes a polypeptide chain‚ it will take
