Photosynthesis depends on an interaction between two sets of reactions: the light reactions and the Calvin cycle. Chlorophyll and the other molecules responsible for the light reactions are built into the thylakoid membranes. The enzymes that catalyze the Calvin cycle are located in the stroma. Beginning with the absorption of light by chlorophyll‚ the light reactions convert light energy into chemical energy in the form of ATP and NADPH. The ATP provides the energy‚ and the NADPH supplies the electrons

Lauren Spillers Biology 1408 February 5‚ 2013 Lung Cancer Lung cancer is the number one form of deadly cancer in the United States. It is not only something that can kill you but also can put a strain on you and your family financially‚ emotionally‚ and medically. Lung cancer is formed when the cells of the lungs grow in an uncontrolled way‚ this creates a lump or a tumor which can either be malignant (cancerous) or benign (not cancerous). Radon gases‚ smoking‚ and second hand smoke cause lung

An essay about cycles in biology. Jessie Dean Biological cycles are vital in many aspects of life on earth. From cycles within the body that keep organisms alive such as the cell cycle‚ Krebs cycle and the Calvin cycle to cycles that encompass many aspects of life and our planet such as the Nitrogen and Carbon cycles. The cell cycle involves actively dividing eukaryotic cells passing through a series of stages known collectively as the cell cycle. The two gap phases (G1 and G2) and S (for synthesis)

Experiments investigating the effect of a particular factor on an enzyme-catalysed reaction are commonly used as assessed practicals in Biology. The reason for this is there are a number of factors that can be investigated‚ and therefore‚ a number of factors that can also be controlled. From our lecture‚ we are aware that the following can affect the rate of reaction: 1) Temperature: a. Independent variable: A range of temperatures should be investigated‚ with particular attention

If you were to ask people in the street‚ “What are human rights?” you would get many different answers. The Merriam Webster online dictionary defines human rights as “rights that belong to an individual as a consequence of being human”. Basically‚ they are the rights you have simply because you are human. The main sources of the creation of human rights are the Universal Declaration of Human Rights and the many human rights documents and treaties that followed in international organizations such

Acid Rain Done By: Francis Lolas Teacher: Christine Due Date: 19/9/2012 Grade: 10 MYP 5 A There are many possible solutions to the problem that we are facing nowadays that is Acid Rain. Acid rain is formed from two main gases that are released in the atmosphere which are sulphur oxide and nitrogen oxide. I will talk later about the solutions for acid rain and the effect of this rain and what are the two forms of acid deposition. I have also watched some videos about acid
