Cyanide binds better to cytochrome 3a than oxygen and this affects the electron transport chain.  The last step in the electron transport chain is the transfer of electrons to oxygen gas using the cytochrome protein.  Cyanide binding to the cytochrome locks the protein and prevents electron transfer out of cytochrome 3a.  This messes up the whole electron transport chain as everything gets backed up in the mitochondrial inner membrane, which is where the cytochrome and other electron transport proteins are located.  \n\nSo when the electron transport chain is backed up this prevents the reducing power created in glycolysis and the Krebs Cycle from being used.  The reducing power from those two processes is what is used to create most of the energy derived from respiration.  So without use of the electron transport chain, which does not work when cyanide is present, only 3 or 4 ATP are made per glucose in the respiration reactions.  With the electron transport chain, in the absence of cyanide, about 34 ATP total are made from the respiration reactions.  \n\nSo overall cyanide greatly reduces the efficiency of respiration by preventing the use of a critical respiration protein.  The presence of cyanide in a cell can cause cell death within minutes due to the extreme inefficiency at which the cell produces energy.

Biotic vs. Abiotic \n \nAbiotic Factors\nAbiotic factors are those non-living physical and chemical factors which affect the ability of organisms to survive and reproduce.    \n\nSome Abiotic Factors\n \nlight intensity \ntemperature range \ntype of soil or rock \npH level \n(acidity or alkalinity) \nwater availability \ndissolved gases \nlevel of pollutant \n \n\nAbiotic factors vary in the environment and determining the types and numbers of organisms that exist in that environment.   Factors which determine the types and numbers of organisms of a species in an ecosystem are called limiting factors.   Many limiting factors restrict the growth of populations in nature.  An example of this would include low annual average temperature average common to the Arctic restricts the growth of trees, as the subsoil is permanently frozen.\n\nBiotic Factors\nBiotic factors are all the living things or their materials that directly or indirectly affect an organism in its environment.   This would include organisms, their presence, parts, interaction, and wastes.  Factors such as parasitism, disease, and predation (one animal eating another) would also be classified as biotic factors.\n\nSome Biotic Factors\n \nparasitism \ndisease \npredation \n \n\nCarrying Capacity\nCarrying capacity is the maximum number of organisms the resources of an ecosystem can support.   The carrying capacity of the environment is limited by the available abiotic and biotic resources (limiting factors), as well as the ability of ecosystems to recycle the residue of dead organisms through the activities of bacteria and fungi.\n\n http://regentsprep.org/Regents/biology/units/ecology/biotic.cfm\n\nThat was a little intro.  Now think about it how does light intensity and temperature affect us and our environment(those would be abiotic.  They help us and other organisms to grow and survive among other things)  and how does disease and stuff affect our lives(biotic)?

Read "aquatic adaptation" from any standard biology book. It will ans both ur qst.

Absolutely..Cell Bio is a great area.  I've been dealing with cell biology for a whole lot of years,  and I still find it fascinating.

Studying for biology can seem overwhelming, but it doesn't have to be. If you follow a few simple steps, studying for biology will be less stressful and more enjoyable. I've compiled a list of several helpful biology study tips for biology students. Whether you're in middle school, high school, or college, these tips are bound to produce results!\n\nBiology Study Tips\n\nBio-Study Tip 1\n\nAlways read the lecture material before the classroom lecture. I know, I know--you don't have time, but believe me, it makes an immense difference. \n\nBio-Study Tip 2\n\nBiology, like most sciences, is hands-on. Most of us learn best when we are actively participating in a "topic." So make sure to pay attention in lab sessions and actually perform the experiments. Remember, you won't be graded on your lab partner's ability to perform an experiment, but your own.\n\nBio-Study Tip 3\n\nSit in the front of the class. Simple, yet effective. College students, pay close attention. You'll need recommendations one day, so make sure your professor knows you by name and you aren't 1 face in 400.\n\nBio-Study Tip 4\n\nCompare notes with a friend. Since much of biology tends to be abstract, have a "note buddy." Each day after class compare notes with your buddy and fill in any gaps. Two heads are better than one!\n\nBio-Study Tip 5\n\nUse the "lull" period between classes to immediately review the biology notes you have just taken. \n\nBio-Study Tip 6\n\nDon't cram! As a rule, you should start studying for biology exams a minimum of two weeks prior to the exam. \n\nBio-Study Tip 7\n\nThis tip is very important -- stay awake in class. I've observed too many people snoozing (even snoring!) in the middle of class. Osmosis may work for water absorption, but it won't work when it comes time for biology exams. \n\nBio-Study Tip 8\n\nFind some useful resources to help you when you study after class. Here are a few resources that I would suggest to help make learning biology interesting and fun:

You might try posting this question in the general biology area, it seems to get a bit more traffic than over here. Good luck.
