Global Warming - What Causes the Greenhouse Effect?
The Earth is kept warm by it's atmosphere, . Heat from the sun passes through the atmosphere, warming it up, and most of it warms the surface of the planet. As the Earth warms up, it emits heat in the form of infra-red radiation - much like a hot pan emits heat even after it's taken away from the cooker. Some of this heat is trapped by the atmosphere, but the rest escapes into space.

Global Warming and Its Effects
Global warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions. This results in an increased emission of greenhouse gases. Climate changes occur in our earth's atmosphere due to a buildup of greenhouse gases. Greenhouse gases can occur naturally as well as a result of human activities. Problems can occur when higher concentrations of greenhouse gases are present in our atmosphere

Glowing Bacteria Lab
Bio 11H lab Introduction: In this lab we are going to make protein glow by bacterial transformation. Bacterial transformation is done by inserting DNA into bacteria where it will replicate. It uses an inducible promoter to regulate gene expression. We used a special RNA Polymerase (T7) which is controlled by the LAC promoter. Without the T7 polymerase glowing proteins could not be expressed. Normally the Lac repressor is activated making the glowing proteins non expressible.

Glycogen Synthesis
Animals synthesize and store glycogen when glucose levels are high, but the synthetic pathway is not merely a reversal of the glycogen phosphorylase reaction. High levels of phosphate in the cell favor glycogen breakdown and prevent the phosphorylase reaction from synthesizing glycogen in vivo, in spite of the fact that ?G°' for the phosphorylase reaction actually favors glycogen synthesis. Hence, another reaction pathway must be employed in the cell for the net synthesis of glycogen.
